List of The Venture Bros. characters

Dr. Rusty Venture

Dr. Thaddeus "Rusty" Venture (voiced by James Urbaniak) is a Super-Scientist and a former child star. He is father to two sons Hank Venture and Dean Venture, and is later revealed in the show to be the illegitimate father of Dermott Fictel. He lives in the Venture Compound, the estate which he inherited from his late father, Jonas Venture Sr. He is always working on coming up with new inventions and ideas to try profit off of, but his creations have little influence in the super science world due to their uselessness and poor construction, they are incredibly prone to breaking and malfunctioning at any given moment. However, He is shown to be very skilled in biology, especially when it comes to cloning technology, which is unfortunately illegal. He is constantly inventing to try to live up to his father’s legacy, but is often mocked and belittled by others for this.

As a child, he was known as the star of “The Rusty Venture Show”, an in-universe fictional cartoon that was loosely based on the adventures of the former ‘Team Venture’ and a direct parody of Johnny Quest. The show would depict Rusty and Team Venture going on adventures to a multitude of locations around the world, fighting villains and solving puzzles, but many events were dramatised, and did not accurately depict the real events that took place. Behind the scenes, Rusty was frequently kidnapped and tortured by the arch-nemesis’s of Jonas Venture, and experienced physical, psychological and sexual abuse at the hands of Team Venture. These memories still continue to haunt him in the present as he is clearly shown to experience PTSD, and abuses drugs he nicknames ‘diet pills’ as a way to cope with stress.

In the first few episodes of Season 1, He is shown to have frequent nightmares of himself in the womb, often consuming his twin in utero. When later, In “Return To Spider-Skull Island”, He is rushed to the hospital with what appeared to be a tumour. After the surgery was performed, it was discovered that it was not in-fact a tumour, but the aforementioned twin who he had carried inside of him for 43 years. The twin’s first instinct was to attempt to kill Dr. Venture, but after a short struggle the two managed to reconcile. The twin decided to take on the name Jonas “JJ” Venture Jr. after the late Jonas Venture Sr. , And was given the X-2 and ownership of Spider-Skull Island by Dr. Venture as a means of sharing the assets their father passed onto them.

Brock Samson

Brock Fitzgerald Samson (voiced by Patrick Warburton) is the Venture family's bodyguard. He was born in Omaha, Nebraska, to a single mother, and is of Swedish, Polish, and Winnebago descent. He attended the same university as Dr. Venture until he was expelled for accidentally killing one of his football team's teammates. Despite holding a license to kill, Brock eschews guns and instead favors a Ka-Bar knife as his signature weapon. He grapples with his role in the world and his purpose, guided by a personal code of ethics concerning innocents and whom he will eliminate if they pose a threat to himself or the Ventures. Brock owns an orange 1969 Dodge Hemi Charger named "Adrianne", frequently seen driving or shirtlessly washing at the Venture compound. Following the explosion of the car carrying Henchman 24, H.E.L.P.eR.'s head was briefly embedded in Brock's chest, leading to 24's death; the head was later removed and replaced with a metal plate. Brock is reassigned back as the Venture's bodyguard after Dr. Venture moves to New York City and inherits the fortune left to him by his late brother JJ.

Hank Venture

Henry Allen "Hank" Venture (voiced by Christopher McCulloch) is the eldest son of Dr. Venture. He emerges as the more extroverted and adventurous of the pair, drawn to action and thrill-seeking, often envisioning himself as a vigilante superhero. In season 4, he exhibits increased rebelliousness following Brock's departure, even losing his virginity to an older woman who happens to be his best friend's mother. After briefly affiliating with former Henchman 21's rendition of S.P.H.I.N.X., Hank acquires the power suit of former S.P.H.I.N.X. member Countess, donning it until it is stolen and destroyed. This incident leads to Hank undergoing physical therapy due to muscle atrophy. In season 6, he opts out of college and takes on a job as a delivery boy at a pizzeria. Additionally, he embarks on a romantic relationship with Sirena Ong, the daughter of his father's current Guild-assigned villain, Wide Wale. In season 7, Hank receives a concussion and slips into a coma after discovering Sirena's infidelity with Dean but eventually recovers.

Dean Venture

Dean Venture (voiced by Michael Sinterniklaas) is the younger son of Dr. Venture, Dean is the younger fraternal twin with red hair. Despite being more timid than Hank, he exhibits signs of greater emotional maturity. Dean garners more favor from their father, who grooms him to succeed as the heir to Venture Industries. Like his brother, Dean has faced death over a dozen times, only to be replaced by an exact clone each time, devoid of memories of his death. Following a breakup with Triana and the revelation of his clone status, Dean adopts a more emo persona, donning a black "speedsuit" and relocating from his childhood bedroom, displaying reluctance to join family adventures. However, Hank's optimism and familial support pull him out of his emotional slump. In season 6, Dean enrolls at the fictional Stuyvestant University in New York, excelling as a philosophy student and befriending Brown Widow, his roommate. In season 7, he engages in an affair with Hank's girlfriend, Sirena Ong, but later regrets his actions.

H.E.L.P.eR.

H.E.L.P.eR. (voiced by Christopher McCulloch; credited as "Soul-Bot"): H.E.L.P.eR., short for Humanoid Electronic Lab Partner Robot, serves as the Venture family's helper robot, communicating through electronic beeps. Despite his sensitivity, the Ventures often regard him as an old appliance or pet. Throughout their adventures, H.E.L.P.eR. frequently gets smashed to pieces but miraculously appears repaired by the next episode.

Sergeant Hatred

Sergeant Hatred, also known as Courtney Robert Haine, is voiced by Brendon Small in season 2 and Christopher McCulloch from season 3 onward. He serves as Brock's former supervisor in the O.S.I., the husband of Native American villainess Princess Tinyfeet, and the Venture family's bodyguard. He is a large, muscular man with a giant red 'H' tattooed on his face, often seen wearing military fatigues. Despite being a convicted sex offender for having slept with a 17-year-old, he is liked and respected throughout the supervillain community for his unfailing politeness and generosity; certain episodes also reveal that he knows his sexual attraction to teenagers is wrong, and tries to keep it in check using a medication called "nomolestol" and electroshock therapy. He is known for his caring nature beneath his battle-hardened exterior. It's implied through flashbacks that his ephebophilia is possibly a side effect from a super soldier experiment done on him, which also causes him to gradually grow breasts.

Dermott Fictel

Dermott Fictel (voiced by Doc Hammer) is an obnoxious teenager who first appears in "The Buddy System"; he was hinted to be the son of Brock Samson. Dermott is a compulsive liar and frequently interjects wild, and often clearly false, claims about his abilities and past deeds into unrelated conversations. He is Hank's best friend and occasionally visits the Venture compound from the nearby trailer park where he and his "mother" live. In "Everybody Comes to Hank's", Hank sleeps with Nikki Fictel (voiced by Kate McKinnon), whom Dermott knows as his older sister, but is actually his mother. His real father is also revealed to be Rusty, making him Hank and Dean's half-brother. He stays behind when the Venture family moves to New York and later joins the OSI, being accepted as an operative despite his lack of training, thanks to a good word put in for him by Dr. Venture.

Dr. Jonas Venture Jr.

Dr. Jonas Venture Jr., also known as J.J. (voiced by James Urbaniak) is Dr. Venture's deformed twin, who was absorbed by Rusty in the womb and surgically freed from Rusty's body after being mistaken for a tumor. Although he has the body of an infant, he has an adult appearance and seems to have inherited his father's brilliance. He is scientifically astute, hard-working, attractive to women, and a multi-billionaire CEO of a profitable corporation. However, his worship of his father causes the original Team Venture to dislike him greatly, as he ignores their importance to his father's life, business, and legacy. JJ dies in "All This and Gargantua-2" when he sacrifices himself to prevent his space station, Gargantua-2, from harming people, when it self-destructs due to sabotage from The Investors. In his will, he bequeaths his fortune, the New York City Headquarters, and technology patents to his brother.

Triana Orpheus

Triana Orpheus (voiced by Lisa Hammer) is Dr. Orpheus's 17-year-old quasi-goth daughter. She has purple hair and is fairly friendly with the Venture twins. She and Dean become close until they have a major fight and fall out after she chooses to date another boy named Raven over Dean. In season four, it is revealed that she has inherited her father's abilities when she encounters her father's mystical mentor, who purposely took up residence in her closet because of her power.

Pete White

Pete White (voiced by Christopher McCulloch) is an albino computer scientist and co-founder of Conjectural Technologies. He attended college with Venture, Samson, Baron Ünderbheit, and Monarch, where he hosted a new wave radio show called "The White Room". After earning a doctorate in computer science, White and Billy Quizboy collaborated on a Jeopardy!-style game show called QuizBoys, with Pete as the host and Billy as a contestant. However, they were fired for cheating and rigging the shows in their favor. Despite a brief falling out, Pete eventually reunited with Billy. They took up residence in a trailer near the Venture Compound. Like Venture and Quizboy, White is skilled and knowledgeable in super science and technology but tends to be lazy and half-hearted in his efforts. In season six, after Dr. Venture inherits his brother's company and fortune, Pete and Billy move to New York City with the Venture family. There, they become leading scientists for Dr. Venture, assisting him in inventing breakthrough technology to sell through Ventech.

Billy Quizboy

William Whalen, a.k.a. Master Billy Quizboy (voiced by Doc Hammer) is an adult and self-proclaimed "boy genius" with a speech impediment and growth hormone deficiency. Despite suffering from hydrocephalus, his intellect remains unaffected. He gained recognition as a contestant on the game show Quizboys, hosted by Pete White. When White cheated on his behalf, they were both disqualified from the show, and Billy's winnings were seized by the SEC. Seeking employment, White and Billy approached Dr. Venture, but were rejected. Later, in a misunderstanding, Billy lost a hand and an eye in a dogfight. Subsequently, he was recruited by Brock Samson and Hunter Gathers, who equipped him with a mechanical hand and camera eye for undercover work. While spying on Professor Hamilton Fantomas, Billy suffered an accident that led to the creation of Phantom Limb and the loss of his left eye once again. Despite lacking formal education, he became a medical doctor, neurogeneticist, and co-founder of Conjectural Technologies. He briefly joined the Order of the Triad after performing brain surgery on the Outrider. In season 5, his old nemesis Augustus St. Cloud became his and White's designated arch-enemy. In season 6, he and Peter relocate to New York City with the Venture family to assist Dr. Venture in developing breakthrough technology for the Ventech brand.

The Pirate Captain

The Pirate Captain (voiced by Christopher McCulloch) is the leader of the "ghost pirates" in "Ghosts of the Sargasso". Following his initial encounter with the Venture family, he took up residence on the X-2 after facing challenges finding employment. When Jonas Jr. acquired the ship, he hired the captain, who has only been addressed as "The Captain" thus far. He lived with Jonas Jr. on Spider Skull Island, assuming roles such as butler, caretaker, and right-hand man. The Captain consistently refers to Jonas as "Chairman". Subsequently, after J.J.'s death, he becomes an employee of Dr. Venture upon inheriting J.J.'s New York City business. The Captain is also a recovering addict, falling off the wagon after being dosed with a tranquilizer.

Bobbi St. Simone

Bobbi St. Simone (voiced by Jane Lynch) is the proprietor of a sanctuary for cybernetic animals. In the 1960s, she was an actress in a bikini movie who had an affair with Jonas Venture, who also bestowed upon her invisibility powers. Following the failure of her film, Jonas coerced her to work for the O.S.I. as a mole within The Guild of Calamitous Intent. She later assumed the identity of Madame Majeure after falling in love with and marrying Force Majeure. However, she fled with her daughter Debbie after Force Majeure was murdered by The Sovereign. Bobbi struck a deal with Dr. Venture to transfer her powers to her daughter, implying that this was in exchange for Debbie's eggs, making her Hank and Dean's biological grandmother.

The Order of the Triad

Original Team Venture

• Dr. Jonas Venture Sr. (voiced by Paul Boocock): Deceased father of Dr. Rusty Venture, Jonas Junior, and as of season 7, it is revealed that he is also Monarch's father. He was the foremost super scientist and adventurer of his time, creating what is now known as Venture Industries and leading the original Team Venture. Despite his public image as a brilliant scientist and superhero, Jonas was revealed to be a manipulative, sociopathic womanizer with questionable morals and ethics, considered by the Guild to have been a greater villain than any of those he fought. He appeared to view Rusty as an unplanned and unwanted birth, often ignoring his son's existence in favor of drinking, partying, and pursuing sexual encounters. When he did acknowledge Rusty, he subjected him to years of emotional manipulation and abuse. Season 7 reveals that Jonas blackmailed his best friend Blue Morpho with a sex tape showing him cheating on his wife, forcing Morpho to do his dirty work for him. This involved coercing Morpho's sidekick, Kano, into joining Team Venture and impregnating Morpho's wife under the guise of "assisting" with their infertility issues. Morpho's wife gave birth to a baby fathered by Jonas, who would later grow up to be Monarch. When Morpho died in a plane crash, Jonas transferred his brain into a robot body, naming him Venturion, an act that disgusted and horrified the original Team Venture. When Venturion malfunctioned and attacked Rusty Venture, Kano fatally disabled it, and Jonas disposed of its remains. Venturion's body was captured by Dr. Zinn and the Guild of Calamitous Intent, who reprogrammed him into a villain called Vendata. He later confronts and kills Jonas by ejecting him into space. Team Venture recovered his remains and embedded them in the ProBLEM device on the station, keeping him in stasis until he could be saved. Years later, his son JJ found the ProBLEM after Gargantua-1 crashed on Earth. Unaware of its contents, he placed it in the lobby of Ventech headquarters as an art piece, inadvertently wiring it into the building's security and technology. Despite his physical death, his brain remained alive and used the building's connection to upload his consciousness, haunting Dr. Venture and his family. Through the building's Wi-Fi, he reveals his true purpose for Venturion/Vendata to Rusty and the original Team Venture: to transfer his consciousness into Vendata's brain, using the robot as a temporary vessel until Rusty could clone him a new body. This plan was thwarted by Vendata/Blue Morpho, who destroyed the ProBLEM machine in a virtual reality fight with Jonas.
• The Action Man, whose real name is Rodney (voiced by Christopher McCulloch), is a retired American supersoldier with flatulence problems and "plastic knees" that hinder his movements. He married Major Tom's widow, Jeannie, after Tom's tragic accident. Like Jonas, he was not well trained with children and was hinted to have had some bad moments with young Rusty. He had a habit of waking up Rusty Venture back in the old days by placing an unloaded gun against the sleeping boy's head and pulling the trigger, then saying, "Not today, Rusty". According to Rose, Rodney was a womanizer and a junkie, both of which he denied, claiming it was all in the past and never cheated on Jeannie, which is most likely a lie. "Action Man" is also the name of Hasbro's original 12 Inch GI Joe figures, released outside the United States. The Action Man moved to a retirement community in Boca Raton, Florida, where he is alone following the death of Jeannie. He briefly had Dr. Entmann as a roommate, only to accidentally crush him with his rocking chair while Dr. Entmann was in a shrunken-down state. He later dates fellow retired superhero, and Billy Quizboy's mother, Rose, and moves in with Colonel Gentleman.
• Colonel Horace Gentleman (voiced by Christopher McCulloch impersonating Sean Connery): A retired member of the original Team Venture and later ersatz leader of the reformed Team Venture. He is a Scottish gentleman and adventurer in the vein of Allan Quatermain and James Bond. The influence is apparent in the similarity of his voice to that of Sean Connery, who has played both characters in movies. He dresses in an old-fashioned British suit, complete with cane and fedora. It is briefly implied that he is a pederast, and this was later confirmed by the creators. In the second season, Hank and Dean find him apparently dead of unspecified causes; however, it is revealed in "Now Museum-Now You Don't" that he was merely in a diabetic coma and is still alive. He is an ethnic/gender chauvinist, and has a penchant for writing out random lists in his notebook. He briefly bears a grudge against Rusty Venture for breaking the heart of his stepdaughter, Dr. Quymn, for whom he has retained some affection. Col. Gentleman lives in Tangier, it formerly being a haven for the world's elite and greatest intellectuals, but in recent years he has realized that he is the only one left, and is dejected that Kiki has broken up with him for the last time. At the end of season 5, he realizes that there is no reason for him to stay in Tangier anymore and moves back to the United States, becoming the Action Man's new roommate.
• Kano (voiced by Christopher McCulloch): A retired member of the original Team Venture, Kano is a master of martial arts and an accomplished pilot, likely inspired by the Green Hornet's assistant, Kato. In earlier episodes, he never speaks and communicates only through origami and sparse gestures; however, this is attributed to a vow of silence he took, revealed in the episode "ORB". This vow was made when he took a great man from the world, which Brock believed to be Jonas Venture Sr. As described by Col. Gentleman, his hands are "powerful enough to crush a boulder, yet delicate enough to crush a butterfly." Although not a villain, his silent demeanor, fighting skills, and brute strength correspond with the bodyguard/henchman archetype found in many works of fiction, with particular similarities to Oddjob. In addition to his skill in fighting and origami, Kano also appears to be a capable aircraft pilot. Kano has also displayed the ability to breathe fire in the episode "Now Museum-Now You Don't". On the DVD commentary, it is revealed that his name originates from "Volcano". Season 7 revealed that Kano was originally the bodyguard of the Blue Morpho, The Monarch's father. Kano was forced into the original Team Venture away from Blue Morpho after Jonas had blackmailed Morpho. When Jonas resurrected the Blue Morpho as the cyborg Venturion after his death in a plane crash, Venturion malfunctioned and attacked Rusty, forcing Kano to snap his neck. According to the other members of the original team, Kano never spoke again after this event, thus "the great man" whom Kano killed before taking his vow of silence.
• Otto Aquarius (voiced by T. Ryder Smith): A retired member of the original Team Venture, Otto Aquarius is an exiled son of Atlantis. He is half-human and half-Atlantean, granting him a greatly extended life-span and the power to communicate telepathically with sea creatures. Aquarius converted to either the Church of Jesus Christ of Latter-day Saints (according to the special features section of the Season 1 DVD) or the Jehovah's Witnesses (according to Christopher McCulloch's blog), though his bizarre appearance often sabotages his attempts at evangelism. Due to his newfound faith, he is now a pacifist, which seems to confirm that he is a Jehovah's Witness.
• Dr. Entmann (voiced by Stephen DeStefano): A tiny man left abandoned in a nuclear fallout shelter, Dr. Entmann was previously a heroic figure known as Humongeloid, standing at 15 feet tall, flabby, and curly-haired. Brock Samson discovers Dr. Entmann in a disused and abandoned lab below the Venture Compound, where he had been trapped for some 30 years since an experiment to shrink him went disastrously wrong. Dr. Entmann moves in with Action Man but is later accidentally killed when Action Man crushes him.
• Swifty (voiced by Brendon Small): An African-American boxer and former bodyguard to Dr. Jonas Venture. In flashbacks, Swifty is shown using a pair of jet-powered boots. Currently, he has dementia due to years of boxing and works as a janitor on Spider-Skull Island.
• Hector (voiced by Brendon Small): A Hispanic boy and childhood friend of Rusty Venture. Seen in a flashback, he used an Aztec calendar to prevent an arrow from injuring Jonas Venture. Hector then joined the original Team Venture as Rusty's companion. However, as revealed in "Powerless in the Face of Death", in the present day, Rusty has no recollection of Hector or their adventures together. Hector reveals that he has been living in a part of the Venture compound closed off by Rusty years prior, unaware that it had been closed or that Jonas Venture had died, at which point Rusty unceremoniously evicts him. Hector appears to be the proxy of Hadji from Jonny Quest in the original Team Venture.
• Ook Ook: A caveman-like member of the team. In the present day, Ook Ook's body is encased in ice for unknown reasons.

The Guild of Calamitous Intent

The Guild of Calamitous Intent is the primary antagonist in the series. It functions as an organization of supervillains, akin to a trade union, offering benefits such as health insurance and establishing rules and conduct standards among its members and their adversaries, primarily superheroes and super-scientists. Serving as a stabilizing force in the world of supervillainy, the Guild prevents unchecked chaos by organizing its members into a cohesive force and restricting their actions to Guild-approved targets, thereby curbing total destruction, murder, and mayhem. Initially led by the enigmatic figure known as "The Sovereign" and the Council of Thirteen, the current iteration of the Guild suggests a refuge for missing or presumed deceased rock stars. In Season 6, most of the Council of 13 is eliminated by The Sovereign to solidify control and confront the supernatural supervillain group, The Investors. Following The Sovereign's accidental death at the hands of O.S.I., surviving members, including Dr. Mrs. The Monarch, Dr. Phineas Phage, Dr. Z, Red Mantle, and Dragoon, under Dr. Henry Killinger's guidance, form a new Council of 13, with assistance from the surviving Revenge Society members, after Killinger eradicates the Investors to restore balance between O.S.I. and the Guild. Although Killinger declines the Sovereign role, he bestows control of the Guild to the council. Season six introduces the New York branch of the Guild, comprising the organization's most dangerous supervillains. Notably, the original Guild charter does not stipulate a specific number of council members, and members cannot actively engage in arching their enemies.

The current iteration of the Guild was reportedly established around 1959 by Phantom Limb's grandfather. However, its roots extend back to the late Victorian era, when it operated as a heroic organization under the leadership of Colonel Lloyd Venture, Rusty Venture's grandfather. This earlier incarnation was devoted to safeguarding an enigmatic artifact known as the "ORB." A schism within the organization arose over differing views on the ORB's purpose. Fantomas founded the Guild of Calamitous Intent in 1910, advocating for using the ORB to dominate mankind, while Lloyd established the modern version of the OSI, aiming to utilize the ORB for the betterment of humanity.

The Council of Thirteen

The governing body of the Guild of Calamitous Intent consists of the following known members:

The Revenge Society

A newly formed, independent organization of villains primarily established to counter the Guild of Calamitous Intent. Consequently, several of its members have had negative encounters with the Guild in the past. The society's founder is Phantom Limb, who initially conceived it as his "team" to acquire the ORB for use against the Guild. However, this version of the Revenge Society consisted solely of Phantom Limb himself, along with inanimate objects he believed to be real individuals: a coffee mug named Wisdom, a toaster named Chuck, and a shoe called Lady Nightshade. After escaping Guild custody, Phantom Limb joined forces with Richard Impossible to establish the current Revenge Society. This iteration has swiftly achieved success in the realm of villainy, although they failed to eliminate Dr. Venture twice in "Bright Lights, Dean City." The group has since been effectively disbanded as of "All This and Gargantua-2."

• The Phantom Limb (Hamilton G. Fantomos) (voiced by James Urbaniak): A villain characterized by his invisible arms and legs. Despite his cunning and ruthlessness, he exhibits a refined cultural taste, as evidenced by his appreciation for Persian rugs and fine cheeses. However, he often comes across as pretentious and occasionally oblivious to the consequences of his actions, seemingly too engrossed in his persona to fully comprehend his deeds. Formerly a professor at the same state college attended by many characters in the show, he was disowned by his family of adventurers due to his tiny, deformed limbs. When Billy Quizboy was sent by O.S.I. to spy on him, Fantomos appointed Billy as his lab assistant, believing him to possess a brilliant mind. During an experiment aimed at normalizing his limbs, a malfunction occurred, resulting in them not only reaching normal size but also becoming invisible and granting him the ability to kill with a mere touch. He was once romantically involved with Dr. Girlfriend, but she ultimately left him for Monarch due to his controlling and possessive nature.
• Professor Richard Impossible (voiced by Stephen Colbert in seasons 1, 2, and "All This and Gargantua-2", Peter McCulloch in "The Terrible Secret of Turtle Bay", Christopher McCulloch in season 3, and Bill Hader in season 4): The founder of Impossible Industries, a prominent government contractor, and former professor to Dr. Venture, Mr. White, Billy Quizboy, and Dean Venture, whom he hired as an intern. He holds science and the pursuit of knowledge in high esteem, often to the point of appearing ruthlessly homicidal or simply out of touch, causing tension with his wife, Sally. Impossible and his associates are a parody of the Fantastic Four: following an experiment with cosmic radiation, each gained peculiar abilities. Richard, akin to Mister Fantastic, can stretch his body like rubber, occasionally using this power to appear taller. The other members of his family possess parodies of the other Fantastic Four members' powers. In a state of disarray and depression, Richard Impossible is depicted in "Pomp & Circuitry" after enduring a series of hardships, including his wife leaving him for JJ Venture, being recruited by Phantom Limb for revenge against the Guild, and ultimately forming a new Guild with Phantom Limb. Assuming the supervillain persona of Professor Incorrigible, he later abandons this identity upon realizing his son needs him to be a father, departing Gargantua-2 with his ex-wife and son.
• Baron Werner Ünderbheit (voiced by T. Ryder Smith): A prominent member of the Guild of Calamitous Intent and former oppressive ruler of Ünderland. He sports a prosthetic metal jaw and speaks with a thick, pseudo-German accent. Initially blaming Dr. Venture for the loss of his jaw, it is later revealed that Monarch was actually responsible for the explosion that disfigured Ünderbheit. Following his ousting, he is depicted in "Pomp and Circuitry" begging for money outside Impossible Industries, and in a post-credits scene, he seeks to join Phantom Limb and Professor Impossible's new Guild. He is presumed deceased following the explosion of Gargantua-2.
  • Manservant (voiced by Christopher McCulloch): Baron Ünderbheit's devoted servant, gifted to him on his college birthday. Manservant's loyalty to Ünderbheit borders on the robotic; he communicates in a zombie-like monotone and often appears vacant-eyed. He is shown alongside Baron Ünderbheit in "Pomp and Circuitry", panhandling outside Impossible Industries, and accompanies him in his attempt to join Phantom Limb and Impossible's new Guild. In "Bright Lights, Dean City", he briefly appears with the Revenge Society in a new costume before Ünderbheit, demonstrating his loyalty to the Society, fatally breaks his neck.
• Fat Chance (voiced by Christopher McCulloch): A supervillain recruited into the Revenge Society to fill missing archetypical positions. Following a scientific mishap, Fat Chance's duodenum now harbors a portal to another dimension, allowing him to summon objects that invariably aid him.
• Lyndon Bee (voiced by Christopher McCulloch) and Ladyhawk Johnson (voiced by Mia Barron): A duo of supervillains enlisted into the Revenge Society. By day, Lyndon Bee assumes the form of a bee, while at night, Ladyhawk transforms into a hawk. They are cursed never to be together except during a solar eclipse.
• Radical Left (voiced by Christopher McCulloch): A supervillain incarcerated at Dunwitch Asylum, with half of his body severely disfigured. Drawing inspiration from the DC comics character Two-Face, his persona is divided between radical anarchist ideologies and peaceful inclinations more reminiscent of a typical 1950s suburbanite. He later joins the Revenge Society and subsequently the New Council, as depicted in "All This and Gargantua-2." Season 7 unveils that Radical Left absorbed his nemesis Right Wing in a prior confrontation, resulting in each sharing one half of a complete body, with occasional games deciding who controls their bodily actions.
• Zero (Scott Hall) (voiced by Christopher McCulloch): Initially known as Number One within Monarch's ranks, he is beaten by Brock Samson during a stealth operation on Spider-Skull Island due to his adherence to clichés while attempting sabotage, capturing Brock's attention. Renaming himself Zero, he later collaborates with the original Captain Sunshine to abduct sidekicks worldwide and pit them against each other in battle, only to be thwarted by a rebellion led by Gary. Joining the Revenge Society in their assault on Gargantua-2, his genre blindness ultimately leads to his death. Obsessed with killing Brock, he spends crucial moments monologuing, allowing Brock to snap his neck.

Ünderland

Ünderland is a micronation situated near Michigan. Formerly under the dictatorship of Baron Werner Ünderbheit, the nation enforced mandatory conscription for all men aged 18 and compulsory euthanasia at 40. Notably, Ünderland lacked prisons, with all crimes punishable by death. However, following the events of "Love Bheits", Ünderbheit is ousted, leading to Ünderland's transition to a democracy.

• Girl Hitler (voiced by Mia Barron): Previously one of Baron Ünderbheit's senior advisers, she, along with Catclops and Manic 8-ball, was "executed" for betraying Ünderbheit's trust, though all three survived. With Ünderbheit no longer in power, she assumes the presidency of Ünderland.
• Catclops (voiced by James Urbaniak): A cyclops adorned with a cat's visage and a tail extending from the back of his head. Following their "execution" by tiger-bombs, he and Girl Hitler sought refuge underground, leading a somewhat ineffective band of freedom fighters. With Ünderland liberated, he proposed to Girl Hitler.
• Manic 8-ball (unvoiced): A human possessing the abilities of a Magic 8 Ball. Executed by Baron Ünderbheit for treason alongside Catclops and Girl Hitler, he miraculously survived the tiger attack and subsequent explosion. However, he was apprehended and held captive by Ünderbheit, who utilized his eight-ball power for guidance. Devoid of a mouth, he communicates solely through the yes or no messages displayed on his chest.
• Eunuchs (voiced by Christopher McCulloch and James Urbaniak): A duo of homosexuals employed by Baron Ünderbheit to groom Dawn (Dean Venture) for the Baron's nuptials. The slender member of the pair was initially a college student from Detroit who ventured abroad to Ünderland for a semester, only to be captured and pressed into service as a court eunuch. Upon uncovering Dean's true gender, he opts to withhold the revelation to humiliate Ünderbheit.

Imprisoned villains

• King Gorilla (voiced by Christopher McCulloch): A homosexual gorilla with the ability to speak, who forged a friendship with Monarch while incarcerated. Once a member of the Guild of Calamitous Intent, King Gorilla's membership was revoked after he was imprisoned for the violent murder and rape of Mötley Crüe lead singer Vince Neil during a reality TV program. This high-profile crime led to the Guild disavowing King Gorilla, embittering him and fostering a cynical attitude towards the organization. Despite kidnapping and attempting to assault Monarch, he ultimately assists in the latter's escape from prison, moved by Monarch's pursuit to regain Dr. Girlfriend's affection. Initially believed to have been killed off-screen by Phantom Limb, it was later revealed on Christopher McCulloch's LiveJournal that King Gorilla was slated to return, liberated from prison, in the latter half of the fourth season.
• Mr. Monday (voiced by Christopher McCulloch): An upper-class villain characterized by his monocle and an unusual fixation on Mondays. When Monarch plans his escape for that night, Mr. Monday insists on postponing, asking, "Can't we wait until Monday?" and frequently exclaims phrases such as "Mondaylicious!" Released from prison by Phantom Limb, he is killed by Phantom Limb in "Showdown at Cremation Creek (Part I)".
• Tigeriffic (voiced by Paul Boocock): A former supervillain whose tiger suit granted him superhuman strength and tiger-like abilities.
• White Noise (voiced by Brendon Small): A smoking, racist former television repairman, White Noise underwent a transformation while repairing a TV still connected to a live socket. He expresses concern about Monarch's criminal organization being "racially mixed", fearing the dilution of his purportedly pure white blood. In response, Monarch questions the validity of his claim, questioning whether he even possesses blood and how he knows he's truly white. Speaking with a Southern dialect, White Noise was tasked with aiding in Monarch's escape by eliminating the guards, alongside Dr. Septapus. White Noise is later shot and killed by Phantom Limb on his private grounds.
• Dr. Septapus (voiced by Christopher McCulloch): Another of Monarch's criminal associates during his incarceration, Dr. Septapus possesses seven limbs, including four arms on his sides, one chest arm, and two legs. Like White Noise, he was intended to assist in Monarch's escape by dispatching the guards. However, upon release from prison, he becomes a target for Phantom Limb's hunt on his private property. Dr. Septapus meets his end when shot down from a tree and subsequently shot on the ground.
• Tiny Joseph (voiced by Doc Hammer): Initially seen as one of Monarch's henchmen in a dream sequence within "A Very Venture Christmas", Tiny Joseph later emerges as Monarch's cellmate. Standing just a few inches tall, he engraves a message onto a microdot, intended to be conveyed by a butterfly to Monarch. Additionally, he serves as a projectile in Monarch's makeshift prison dart gun.
• Teddy (voiced by Christopher McCulloch): A criminally insane supervillain bearing severe burns, Teddy once provided the voice for a Teddy Ruxpin-like toy. Incarcerated in Dunwitch Asylum for the Criminally Insane after embracing Ronald Reagan too vigorously, Teddy's toy is utilized by the boys and Hatred to deceive their father into believing he's been abducted by Zeus in "Any Which Way but Zeus". Subsequently, Hank and Dermott employ the same toy to maintain the illusion of conversation with Teddy in "Momma's Boys", employing a prepaid cellphone to keep their father occupied while they slip away. Unwittingly drawn into Myra Brandish's coup attempt, Teddy eventually escapes confinement, rescuing Dr. Venture and Sgt. Hatred from certain peril when their vehicle careens into a ravine en route to "Bygolly Gulch".
• Cuckoo Clocker (voiced by Christopher McCulloch): A supervillain incarcerated at Dunwitch Asylum, sporting a door resembling a cuckoo clock embedded in his head.
• Big Time: A supervillain also detained at Dunwitch Asylum, distinguished by a clock face tattoo adorning his visage, with his mustache fashioned to resemble two clock hands. Both he and Myra Brandish harbor the belief that he possesses temporal manipulation abilities.
• Maybe Man (voiced by Christopher McCulloch): A supervillain confined at Dunwitch Asylum, whom Myra Brandish implores to facilitate Dean's placement within her womb for birth, to which he cryptically responds with "maybe".

Fraternity of Torment

The Fraternity of Torment stands as one of the few supervillain collectives outside the Guild of Calamitous Intent. Comprising mostly marginalized individuals ostracized by society due to various physical deformities, they frequently clashed with Team Venture during the 1960s. However, Jonas and his team often appeared to taunt and bully them for amusement rather than engage them out of a sense of justice. Although the original group's remnants surface in "Now Museum, Now You Don't", they still maintain a presence in the realm of organized supervillainy alongside the "Peril Partnership".

• Scaramantula (voiced by Toby Huss): An Italian supervillain with a spider motif inspired by the James Bond antagonist Scaramanga. Sporting eight fingers on his right hand and a partial spider mask adorning his face, complete with eyebrows and mustache resembling eight legs, he once owned Spider Skull Island. However, an ill-fated attempt to kidnap Rusty Venture led to their defeat by Team Venture. Dr. Venture, infiltrating the group as "Dr. Fanadragon", revealed his true identity, resulting in the Fraternity's downfall. Scaramantula managed to escape and initiated a failed self-destruct sequence, leading to Spider Skull Island's absorption into Venture Industries. Retiring from villainy, Scaramantula maintains peak physical condition from exercising on the island's escape path. Witnessing the desecration of his former home, he aids Brainulo in seeking revenge and narrowly avoids being killed in the self-destruct sequence.
• Brainulo (voiced by Christopher McCulloch): A supervillain hailing from a millennium in the future, Brainulo purportedly found himself stranded in the year 1969 after Dr. Jonas Venture destroyed his means of returning. Utilizing his superior intellect and mental abilities, he commandeered a colossal robot dubbed Futuro. Amidst the assault on Spider Skull Island, Brainulo seized control of Futuro, only to be toppled by the Humongoloid. In the present era, Brainulo is revealed to be a paraplegic, feigning senility as part of a vendetta against Dr. Venture and his progeny. Exploiting the fears and vulnerabilities of attendees at the Jonas Venture Museum's inauguration, he seeks to incite chaos. However, his bid fails, and in a final effort to wrest control of Futuro, he inadvertently shorts his own brain, succumbing to genuine senility. Subsequently, he reappears in the lobby of Impossible Industries during "Bright Lights, Dean City", ostensibly as an applicant to the Revenge Society. Yet, given his motionless, vacant demeanor, it is uncertain whether he intentionally sought entry or simply wandered in.
• Manotaur: A supervillain endowed with superhuman strength, Manotaur faced ostracism due to his formidable size. In a flashback during "Shadowman 9: In the Cradle of Destiny", Monarch falsely claimed to be "Manotaur" to evade reprisal from Phantom Limb after his dalliance with Dr. Girlfriend. However, it is ultimately revealed that Manotaur exists, having retired to a position with the MTA, where he is killed by Phantom Limb.

Peril Partnership

The Peril Partnership is a supervillain coalition headquartered in Toronto, serving as one of several rival factions to the Guild of Calamitous Intent. Members of this organization can be identified by the letters 'PP' on their attire. In season 7, it is unveiled that the Peril Partnership has infiltrated the Guild. However, this revelation exposes a splinter faction comprising some American members of the Peril Partnership, seeking to instigate a conflict between the Guild and their organization, with the aim of usurping control as the preeminent supervillain consortium.

• Tiger Shark (voiced by Christopher McCulloch): A supervillain with a shark motif, Tiger Shark stands as the sole documented member of the Peril Partnership. He makes an appearance in "Any Which Way But Zeus", engaging in a brainstorming session to devise strategies for locating the henchmen and sidekicks who have been abducted. During the encounter, Tiger Shark recounts a past encounter with Brock Samson, highlighting a personal grudge stemming from discovering Brock in a compromising situation with his wife. Despite Brock's lackluster apology, he hints at the possibility of deception on the part of Tiger Shark's spouse.
• The Creep (voiced by James Adomian): Leading the Peril Partnership's splinter faction, The Creep formerly served as an O.S.I agent under the alias Mission Creep. Discharged after an incident where he mistakenly eliminated a Boy Scout troop, he rejected the Guild due to its stringent regulations. Joining the Peril Partnership didn't alleviate his discontent either. Eventually, he formed a dissident group of likeminded villains, aiming to instigate conflict between the Guild and the Partnership. The Creep embarked on a spree, targeting Guild members for sport and acquiring their signature tools to weaponize against the O.S.I. Pursued by Monarch and 21 on orders from both the Guild and O.S.I, he engages them in a lethal game of Lawn Darts, dying after being distracted by the sudden appearance of Dr. Venture and Billy Quizboy from Grover Cleveland's Presidential time machine.
• Blind Rage (voiced by Brendon Small): A blind villain with a pro wrestling motif, Blind Rage operates within the Peril Partnership's splinter cell. Tasked with blackmailing the Council of Thirteen, he faces rejection. Later, he encounters Red Death, who renders him unconscious and binds him to subway tracks, leaving him at the mercy of an approaching train. Whether he survives the ordeal remains undisclosed.

S.P.H.I.N.X.

Originally a terrorist organization that served as the primary adversary of the O.S.I. 20 years ago until its defeat in the Pyramid Wars of 1987. The conflict erupted when S.P.H.I.N.X. seemingly took credit for the Movie Night Massacre on Gargantua-1, resulting in the death of Jonas Venture Sr. and numerous others. However, it was later revealed that the Sovereign had framed S.P.H.I.N.X. using the form of S.P.H.I.N.X. Commander. Disillusioned with the O.S.I.'s bureaucracy, several of its members decided to adopt the S.P.H.I.N.X. identity, along with their surplus equipment, to combat rogue supervillains. By the end of season 4 and the start of season 5, former O.S.I. agents who had joined S.P.H.I.N.X. were reinstated into the O.S.I., leaving Henchman 21 as the sole remaining S.P.H.I.N.X. operative. Gary attempts to recruit new members but inadvertently reunites the original S.P.H.I.N.X. members. Aware that their loyalty chips will soon dissolve, resulting in their death, they prepare for a final suicide attack against the O.S.I. S.P.H.I.N.X.'s rented headquarters within the Venture compound is destroyed in the season 5 episode "S.P.H.I.N.X. Rising", forcing Gary to reside in the Venture's backyard. The original surviving S.P.H.I.N.X. members are:

• Michael/SPHINX Commander (voiced by Christopher McCulloch): A tall man with little control over the volume of his voice. He has been stalking his former lover, Theresa, the Countess. Gary prohibits him from using his former title "SPHINX Commander" as Gary is now the leader. Consequently, Michael adopts the moniker "Mister Daddy Warlord of the Children of the Corn". Later, he seizes control from Gary and abducts Hank, who is wearing the Countess' former power suit. Ultimately, he refuses to surrender Hank and is killed by Brock.
• Theresa/The Countess: SPHINX Commander's former second-in-command and lover, satirizing the Baroness. Her powered armor suit grants enhanced strength and mobility to its wearer. When Hank dons the suit, designed for the Countess, he assumes a feminine appearance and movement. It includes a safeguard preventing harm to the SPHINX Commander. Following SPHINX's defeat, Hank retains the power suit and wears it regularly. Molotov Cocktease pilfers the suit in "O.S.I. Love You", and Brock Samson destroys it to feign Molotov's death.
• Wind Song (voiced by Tim Meadows): A parody of Storm Shadow, Wind Song is an African American ninja and a member of the original S.P.H.I.N.X. During retirement, he has embraced family life and wears Coogi sweaters reminiscent of Cliff Huxtable.
• Diamond Backdraft (voiced by Larry Murphy): A former S.P.H.I.N.X. member specializing in flamethrowing and snake handling.

Other supervillains

• Storm Front (voiced by Christopher McCulloch): A weather-controlling supervillain who protests having his powers temporarily taken away for the think tank in "Any Which Way But Zeus". He claims he won't harm anyone, as his powers are purely precipitation-based.
• Crime-o-dile: A crocodile-themed supervillain previously killed by Captain Sunshine after falling into his own crock-pit, set on fire. A henchman appears in a support group attended by 21 and 24 after Monarch's imprisonment.
• Scorpio (voiced by Christopher McCulloch): Another member of Captain Sunshine's rogues gallery, themed after a scorpion. He later appears in Sgt. Hatred's old home in Malice, having become Princess Tinyfeet's new lover.
• Mantilla (voiced by Nina Arianda): Real name Debra “Debbie” St. Simone. She is the daughter of Bobbi St. Simone and Force Majeure. An ex-girlfriend of Monarch, she is confirmed in director’s commentary to be the egg donor and biological mother of the Venture Bros. She appears to have the ability to turn herself and her clothes invisible due to biological engineering. Additionally, she exhibits vast matter and energy manipulation powers, although the nature of these abilities remains unclear. Mantilla leads the apparent upstart villain guild and smartphone app known as ARCH.

The Impossibles

• Sally Impossible (voiced by Mia Barron): Richard's estranged wife, Sally, possesses invisible skin, leaving her muscle tissue visible and requiring her full concentration to maintain visibility. She harbors a crush on Dr. Venture, although he was repelled upon discovering her condition. Richard has hinted at her infidelity, suggesting their newborn son may not be his. This alludes to the Invisible Woman's relationship with the Sub-Mariner in comic lore. At one point, Richard virtually kept Sally as a prisoner, suspecting her desire to flee. Sally has been romantically involved with Jonas Venture Jr. and resides on Spider Skull Island with the Impossibles, excluding Richard and Cody. Their relationship hits a snag due to JJ's commitment issues, culminating in Sally leaving with Rocket and Richard in "All This and Gargantua-2". She implies that her connection with Richard will be one of shared custody over Rocket, devoid of romance or affection.
• Rocket Impossible: Sally and Richard's newborn son who, thus far, has not displayed any superpowers or genetic mutations.
• Ned (voiced by Christopher McCulloch): Sally and Cody's cousin, living with Down syndrome, who was transformed into a "giant callus" with skin approximately 3 inches (76 mm) thick. He resided with Sally, Rocket, and J.J. on Spider-Skull Island for some time, though his whereabouts during the events of Gargantua-2 were unknown. He later attended J.J.'s funeral with the rest of his family.
• Cody (voiced by Christopher McCulloch): Sally's brother who bursts into flames when exposed to oxygen. Unable to control this reaction, he is kept in an air-tight container, resulting in a state of unconsciousness. In "Bright Lights, Dean City", it's revealed that Professor Impossible has been using an imprisoned Cody to provide clean energy to Impossible Industries, a deed Phantom Limb describes as "the most deliciously evil thing [he'd] ever seen", although Professor Impossible seems oblivious to its true evilness. Cody's fate after being freed from Impossible Industries is unknown.

Jonny Quest characters

• Action Johnny/Jonny Quest (voiced by Brendon Small): Since the death of Dr. Benton Quest, he has been secluded within the Quest Bathysphere, living in isolation and struggling with his addiction to narcotics, as depicted in the episode "Twenty Years to Midnight". He is deceived into handing over a piece of Dr. Venture Sr.'s machinery after being bribed by the Captain and Jonas Jr., an action that Jonas Jr. later regrets. Though he has since gotten sober, he remains a highly anxious individual due to the psychological scars left by his father's negligent parenting. In "The Buddy System", Johnny remarks, "fathers are caring and protective men, and I don't have one of those." In the same episode, Johnny hints at his desire to liberate Dean from his father's influence, but is interrupted by Brock. He also suggests that he staged several crimes to spite his father, including the alleged murder of their dog, Bandit. In subsequent episodes, Johnny shows signs of improvement, mentioning casually in "Self Medication" that he had gone on a date with Velma Dinkley, resulting in him contracting herpes. In "The Terminus Mandate", it is revealed that he is residing in a rehabilitation facility, where he finally reconciles with Dr. Z.
• Race Bannon (voiced by Christopher McCulloch): Brock's friend from the Office of Secret Intelligence, where he once served as a torturer. He is killed after leaping from a jet piloted by Nat King Cobra's Snake Men while retrieving the Goliath Serum. Race is equipped with various spy gadgets reminiscent of those wielded by James Bond.
• Hadji Singh (voiced by Jackson Publick): Another nod to a Jonny Quest character, Hadji now works as a manager alongside Jonas Jr. He is also tasked with looking after Johnny, all the while fretting that if he brings Johnny back home, his own wife will leave him.
• Dr. Z (voiced by Christopher McCulloch): A nod to the recurring villain "Dr. Zin" from the Jonny Quest franchise, he made an appearance in the episode "The Buddy System." In the episode, he was set to be a special guest star in a stage show featuring Action Johnny, performed as part of "Rusty's Day Camp for Boy Adventurers." Upon encountering his old nemesis, Johnny experiences a panic attack and a mental breakdown. Sergeant Hatred, mistakenly interrupting the show as a routine arching, greets Z with enthusiasm, saying, "The Dr. Z! Aw man, I love your work." In "Self-Medication", Dr. Z is confronted by Action Johnny, Dr. Venture, and a group of former "Boy Adventurers" who accuse him of their therapist's murder. However, Dr. Z is innocent, and the group discovers that he is married. During a peaceful dinner, Dr. Z advises the former "Boy Adventurers" to grow up and move on from the past, expressing regret over his own life and wishing for a normal marriage with his wife. In "Pomp and Circuitry", one of the silhouetted members of the Council of 13 bears a striking resemblance to Dr. Z, resembling a homage to Fu Manchu, an evil genius from novels by English author Sax Rohmer. In "What Color is Your Cleansuit?", Dr. Z appears in an old Guild PSA, warning against the dangers of incompetent henchmen. In "Bot Seeks Bot", Dr. Z is confirmed to be a member of the Council of 13. He remains a member of the new Council of 13 in season 6, having survived the Sovereign's purge of the old Council.
• Mrs. Z (voiced by Seth Green): Dr. Z's wife of many years, who remained his "beard" until the two fell in love, although it was too late for them to start a family.

Therapy group members

• Lance (voiced by Seth Green) and Dale Hale (voiced by John Hodgman): The Hale Brothers were once renowned boy detectives until their father's murder, which became the catalyst for their therapy sessions, particularly for Dale, who struggles to cope with the trauma of witnessing their father's death. There are hints suggesting their involvement in the murder, with Lance dismissing the significance of their fingerprints found on the murder weapon, attributing it to their detective work. When Dr. Venture accuses them directly, Lance responds flippantly, suggesting that the accusation was never substantiated, triggering Dale's hysterical reaction, fearing that Dr. Venture may have uncovered the truth. It is suggested that the murder might have been driven by Lance's desire for their inheritance, only to realize that their father's wealth would go to the Boy Detective Academy, leaving them with nothing but a car obtained from the crime scene, which they both hold dear. The Hale Brothers are satirical portrayals of the Hardy Boys and the Menéndez brothers.
• Ro-Boy Z (voiced by Christopher McCulloch): A robotic boy grappling with abandonment issues stemming from his creator/father and developing psychopathic tendencies from a life spent battling giant robots. He harbors anger towards other robots, exhibiting what appears to be pyromaniacal behavior. Eventually, he finds adoption with Dr. Z and his wife Mrs. Z, fulfilling the couple's longing for family while providing Ro-Boy a chance to overcome his past with his creator.

The Super Gang

• Chuck Scarsdale/Captain Sunshine (voiced by Kevin Conroy): A sunlight-powered superhero previously referenced by Monarch regarding the charred remains of Wonder Boy. Captain Sunshine appears in the episode "Handsome Ransom", seeking revenge on Monarch and thwarting his attempt to ransom Hank and Dean from Dr. Venture. He takes Hank under his wing, inducting him as his new sidekick and ward, Wonder Boy. Although there are hints at pederastic tendencies, Jackson Publick has clarified that this is not the case. Instead, Scarsdale's experiences as the original Wonder Boy led to him developing a case of Peter Pan syndrome, reliving the childhood he never had. He lives in a colorful, toy-filled mansion and vicariously experiences youth through his wards. Coupled with guilt over the death of the third Wonder Boy and a habit of directly incarcerating criminals, Scarsdale is depicted as a dangerously out-of-touch figure akin to older superheroes. Despite leading the Action 5 News Team, he abandons his evening broadcast to confront Monarch when he attempts to abduct Hank. During the confrontation, Captain Sunshine is exposed to a device intended to weaken him, but instead, it revitalizes him, enabling him to defeat Monarch. However, he is disappointed when Hank chooses to return home rather than continue as Wonder Boy. In "Any Which Way But Zeus", Red Mantle reveals that Scarsdale was the original Wonder Boy. In "Bot Seeks Bot", Sunshine attends the funeral of his long-time archenemy, Boggles the Clue Clown, and experiences an emotional outburst.
  • Desmond (voiced by Doc Hammer): Captain Sunshine's butler. In "Any Which Way But Zeus", Desmond is revealed to be the original Captain Sunshine, with Scarsdale as his ward Wonder Boy. Desmond also assumes the role of Zeus to advocate for protective laws for sidekicks.
  • Wonderboy (voiced by Patton Oswalt): The first ward of Captain Sunshine. Depressed after being replaced and his subsequent failed career as a hero, he turns to binge eating and joins a therapy group for former boy adventurers. He is assumed to be the second Wonderboy, succeeding Scarsdale and preceding the one killed by Monarch. Another Wonderboy appears in season 5's "Bot Seeks Bot".
  • Wonderboy 5 (voiced by Larry Murphy): Captain Sunshine's current Wonderboy, who appears indifferent to the death of Boggles the Clue Clown. He has to drag Captain Sunshine away when he has an emotional outburst as Boggles' coffin is lowered into his grave. Wonderboy 5 also demonstrates superior detective skills compared to his mentor, solving Clue Clown's final riddle almost immediately when Captain Sunshine was stumped.
• Barbara Qantas/Barbie-Q (voiced by Rachel Feinstein): Chuck Scarsdale's Australian co-anchor who resembles a Barbie doll that can emit pink flames. She is one of Zeus's captives in "Any Which Way But Zeus".
• Sam Turgen/U.S. Steel (voiced by Doc Hammer): The sports anchor for the Action 5 News Team, who doubles as the superhero U.S. Steel, inspired by Uncle Sam. In "Any Which Way But Zeus", U.S. Steel mistakenly anticipates finding Ghost Robot, unaware of his earlier death.
• Neville Brown/Brown Thrasher: Sam Turgen's sports co-anchor, who, as Brown Thrasher, possesses bird-themed powers reminiscent of Falcon from the comics. He is one of Zeus's captives in "Any Which Way But Zeus".
• Weatherbot 5/Ghost Robot (voiced by Christopher McCulloch): Serving as the meteorologist for the Action 5 News Team, Ghost Robot is revealed to be a robot housing a ghost within him. Although presumed dead after 21 shatters his robotic eyes in "Any Which Way But Zeus", he resurfaces alive and well in season 5's "Bot Seeks Bot." Deputized by the O.S.I., Ghost Robot aids in an undercover mission to unveil the identities of the Council of Thirteen by posing as the robotic Guild member Galacticon and going on a date with Vendata. However, his desire for fingers and a mishap resembling the real Galacticon jeopardize the mission, leading to Vendata's death.
