Mixels

Infernites

Based on fire, the Infernites are the red primary tribe of Series 1. They live in the ‘Magma Wastelands’ near the center of ‘Mixel Land’.

• Flain (voiced by Tom Kenny) − Flain is the leader of the tribe called the ‘Infernites’, along with the other Mixels. Flain is adventurous and smart because he is known to his friends as ‘the smart one’. His head is on fire. When he thinks deeply or gets angry, his head runs the risk of catching on fire, so he tries to stay calm.
• Vulk (voiced by Jess Harnell) − Vulk is a one-eyed Mixel who is dimwitted but liked by his friends. Among his looks is how he is one of many cyclopses. His superheated hands can melt through solid rocks and the ‘Nixels’, however he may inadvertently hurt other Mixels with those hands, which make another Mixels not want to have high-fives or anything else with him.
• Zorch (voiced by David P. Smith) − Zorch is an Infernite who has fiery jets that let him "run around with surprising speed". He is a "crazy prankster", but well liked by his friends of whom he sometimes plays pranks on. His fiery jets from his rear leave the Nixels standing in a smoke cloud.

Cragsters

Based on rock, the Cragsters are the secondary tribe of Series 1. They live in tunnels that they have dug deep under the surface of Mixel Land.

• Krader (voiced by David P. Smith) − Krader is a super-strong and tough Mixel with a short temper. Roughly considered the Cragsters' leader, he has a rotating torso and massive hand, which can fold into a demolition ball, allowing him to bulldoze through rocks and dig deep pits to trap the Nixels.
• Seismo (voiced by Tom Kenny) − Seismo is a lanky and shy Mixel who can cause earthquakes with his unusually massive feet; he uses this ability as a weapon against the Nixels.
• Shuff (voiced by Jess Harnell) − Shuff is helpful and friendly, but very clumsy. His body is like "a living wrecking ball", and he accidentally destroys everything with it.

Electroids

Based on electricity, the Electroids are the yellow tertiary tribe of Series 1. They live in the Mountain Forest and stay as close as possible to the lightning storms that energize them.

• Teslo (voiced by Tom Kenny) − Teslo is the leader of the Electroids. He fights with his electrically charged tail. While usually level-headed, he has an open secret fear of heights. He is one of many cyclopses.
• Zaptor (voiced by Jess Harnell) − Zaptor is energetic and thrives on action. He is capable of releasing massive blasts of energy and blinding light, but overuses his ability, much to the chagrin of the other Mixels.
• Volectro (voiced by David P. Smith) − Volectro stores electricity in his hair. When overloaded with electricity, he can draw objects to himself with static electricity that charges his hair.

Frosticons

Based on ice, the Frosticons are the blue secondary tribe of Series 2. They live near the crystalized shells of dead volcanoes.

• Flurr (voiced by Phil LaMarr) − Flurr is the leader of the Frosticons. Flurr is the only Frosticon who never feels sleepy and likes to fly around and explore Frosticon lands. He is good at spotting Nixels that are invaded far away, but sometimes misses obvious things.
• Slumbo (voiced by Fred Tatasciore) − Slumbo is the sleepiest Frosticon. It takes an earthquake to wake him up, but when he is awake, he has the power to move giant objects and create obstacles for the Nixels. Slumbo can brain-freeze the Mixels from making ice tunnels.
• Lunk (voiced by Billy West) − An unbelievably slow Frosticon, Lunk makes the other Frosticons seem positively energetic. He is not the brainiest or the most graceful when waddling across ice and balancing on his stubby hands, but his thick ice exoskeleton makes him incredibly durable. When he is sneezing, he can instantly freeze a Nixel in an ice cube.

Fang Gang

Based on eating and wood, the Fang Gang are the brown primary tribe of Series 2. They live on a farm.

• Gobba (voiced by Billy West) − Gobba is the bite-loving leader of the Fang Gang who can use his sensitive, whiplike tongue to seek out food on his homeland, a farm. He is the best taster of feelings among the Fang Gang, carving totem poles.
• Jawg (voiced by Fred Tatasciore) − Jawg is a character who protects his friends by using his indestructible teeth. He is a dog who can speak, and will not hesitate to bite intruders with his teeth.
• Chomly (voiced by Phil LaMarr) − Chomly is the lazy trash compactor of the Fang Gang who will try to crunch just about anything not nailed down. Chomly is close-talking and has incredibly bad breath. This makes no Mixel wanting to be stuck next to Chomly at a 'Fang Gang food party', but his stinking breath comes in handy for repelling the Nixels.

Flexers

Based on rubber, the Flexers are the orange tertiary tribe of Series 2. They live in the Rubberlands, in line with what they are based on.

• Kraw (voiced by Fred Tatasciore) − Kraw might be short, but he is one confident character. Claiming to be the smartest Mixel, he loves to challenge the Mixels to a quiz, but his main strength is to turn into a bouncy, rubber super ball to evade or smash Nixels. He is one of many cyclopses.
• Tentro (voiced by Phil LaMarr) − The incredibly elasticated Tentro is one of the most powerful of the Flexers. Despite being strong and super intelligent, he lacks confidence. No one knows why, though, because he has tentacles that pack a huge punch and the ability to climb any surface and capture any Nixel who attacks him.
• Balk (voiced by Billy West) − Balk may be the slowest of the Flexers, but his mallet-like head can hit, pummel, and crush whatever is in the way. His head-butting has bashed his brain cells, so he can be forgetful when finding it hard to spit out the right words, yet there is nobody better than him to defend the Rubberlands, where the Flexers themselves live, from Nixel Invasions.

Glorp Corp

Based on slime, the Glorp Corp are the green primary tribe of Series 3. They are swamp-dwelling thrill-seekers.

• Glomp (voiced by Maddie Taylor, later by Jess Harnell in Season 3) − Glomp is the leader of the Glorp Corp.

He is one of many cyclopses.
• Glurt (voiced by Bumper Robinson) − Glurt is a slimy hound-like creature who is the most excitable member of the Glorp Corp. With a pointy tail and a yapping mouth, he slobbers with delight when he sees anyone. An avid garbage collector, he gobbles up all the trash, cleaning up after the Glorp Corp.
• Torts (voiced by Carlos Alazraqui) − Torts has bulky feet and is the slowest-moving member of the Glorp Corp. A slob who enjoys playing for thrills, he shoots gloopy, green slime from his hands. Anything can stick to him, which is great fun when goofing around and perfect for catching Nixels.

Spikels

Based on spikes, the Spikels are the tertiary tribe of Series 3. They live in a feminine-like home.

• Scorpi (voiced by Maria Bamford) − The leader of the Spikels, Scorpi loves bedtime-esque things. He always sees life with wonder and scuttles around on his centipede-like legs when seeking fun. He loves to hug and snuggle, but beware of his dangerous, pointy tail.
• Footi (voiced by Bumper Robinson) − "Livewire" Footi can't stop moving at all. Everyday's moment always bursts with exciting possibilities for him. He loves to skip, jump, and dance. The other Mixels must give him plenty of room when he starts stomping around; his huge, spiky feet are dangerous, so Mixels must watch out. He is characterized as feminine due to his voice.
• Hoogi (voiced by Maddie Taylor, later by Bill Fagerbakke in Season 3) − Hoogi is the slowest-moving of the Spikels. He has giant fang teeth and is also super affectionate, giving the Mixels the best hugs with his lanky arms. He walks as slowly as a zombie, but getting grabbed by his spiky hands can be painful: Mixels may want to avoid one of his hugs.

Wiztastics

Based on magic, the Wiztastics are a purple traveling troupe of magicians and the secondary tribe of Series 3. They live in a magic tent and put on shows for the Mixels.

• Magnifo (voiced by Brian Stepanek) − Magnifo is the most smart and most serious of the Wiztastics. With a wizard's hat, a wizard's cape, and two magic wands, he puts energy into every show with the help of his bumbling assistants. Even if the Mixels think his act is cheesy, they shouldn't tell him or the rest of the Wiztastics; they love it. He is one of many cyclopses.
• Mesmo (voiced by Carlos Alazraqui) − Mesmo looks the part of magic with his expressive wizard-hat eyelids, goatee beard, and magic tail that drops spells. But his problem is that he lacks in showmanship; Mesmo needs help peacocking his huge wings and stealing the show.
• Wizwuz (voiced by Bumper Robinson) − Wizwuz is the over-enthusiastic magician's assistant of the Wiztastics. On stage, he constantly messes up the show, but his improvised antics are half the fun. Whether burping spells or hanging from the ceiling, Wizwuz loves to perform and make the audience laugh.

Orbitons

Based on space, the Orbitons are the secondary tribe of Series 4. They live in Orbitopia of the Mixel Moon.

• Niksput (voiced by Andrew Kishino) − The leader of the Orbitons, Niksput is charismatic but unintelligent, and often pretends to be smarter and braver than he actually is. He can fly at high speeds, but often crashes due to his lack of skill. He is Also one of many cyclopses.
• Nurp-Naut (voiced by Justin Grollman for Nurp, later by Ariel Winter in Season 3 and Rodger Bumpass for Naut) − Nurp-Naut has two personalities : Nurp is playful and childlike, and Naut is serious and mature. These personalities are aware of each other and even communicate with each other. Whenever his personality changes his head spins rapidly. Naut is also one of many cyclopses.
• Rokit (voiced by Phil Hayes, later by John DiMaggio in Season 3) − Rokit is incredibly serious. Whenever he does something, he puts his full effort into it. He is often frustrated about the other Oritons' lack of discipline.

• Meltus (voiced by Jess Harnell) − Meltus may look scary, but he is really a shy and nervous Infernite who is allergic to everything. Even when he walks outside, he starts sneezing fire.
• Flamzer (voiced by Rodger Bumpass) − Dramatic and anxious, he can move quickly, like a scaredy-cat. He is one of many cyclopses.
• Burnard (voiced by Jess Harnell) − Everything is funny to Burnard. He laughs a lot; he even laughs through fear and sadness. Even if he laughs hard enough, he spews fire. However, the only way to make him stop laughing is by telling him a funny joke whose punchline he does not get.

Glowkies

Based on bioluminescence, the Glowkies are the tertiary tribe of Series 4. They live in a cave on the Mixel Moon.
