Blackheart is a demon and the creation of Mephisto, who he has opposed on several occasions. In the 2024 series Avengers Academy: Marvel's Voices, Blackheart refuses to retrieve Billy and Tommy Maximoff for Mephisto, which results in Mephisto transforming Blackheart into a human and banishing him to Earth. Significantly weakened, though retaining a portion of his powers, Blackheart seeks refuge at the Avengers Academy and becomes a student there.
Blackheart was redesigned for the series Avengers Academy: Marvel's Voices, where Mephisto transformed him into a human. Writer Anthony Oliveira and artist Bailie Rosenlund decided to give Blackheart a gothic appearance, with red eyes and a hairstyle resembling his demon form's spiky head. Blackheart has thorn-like tattoos on his upper body, reminiscent of the bramble bushes of Christ's Crown.
Fictional character biography
Blackheart is a demon and the son of Mephisto, who created him from the evil energy that accumulated in Christ's Crown, New York, draws the attention of a Hell-lord, Mephisto, who creates a "son," Blackheart, from evil energy. Blackheart becomes impressed by humanity's free will and concludes that evil cannot hope to win out against good. When Mephisto learns of Blackheart's change of mind, he banishes him to Earth, warning him that if he ever uses his power again, he will be driven mad.
Blackheart uses a dagger tipped with the blood of a young girl to kill Mephisto and take over a portion of Hell. He later tricks Noble Kale and tries to recruit him into his Spirits of Vengeance, promising Kale the power to rule in Hell alongside him. Kale double-crosses Blackheart, freeing the other Spirits of Vengeance and gaining rule over Blackheart's portion of Hell.
Blackheart concocts a scheme to bring Hell to Earth and steal the souls of the planet's residents. As part of the plan, he assumes a human form and runs an operation in Las Vegas that sees him create several clones of X-23 and bond them to genetically created symbiotes. After Ghost Rider accidentally transports Hell to Las Vegas, Blackheart is confronted by Ghost Rider, Venom, Red Hulk, and X-23, and summons four creatures that represent the antitheses of the four and sets them against the heroes.
In Avengers Academy: Marvel's Voices, Blackheart is sent by Mephisto to retrieve the time-displaced souls of Billy and Tommy Maximoff from the Avengers Academy campus. Despite viewing the twins' souls as innocent, Blackheart reluctantly follows through with his father's orders but is thwarted by Bloodline and Escapade. Influenced by Escapade's powers, Blackheart lets the boys go and returns to Hell empty handed. As punishment, Mephisto turns Blackheart into a human with diminished powers and banishes him to Earth. Blackheart requests shelter at the Avengers Academy and is reluctantly allowed to join the student body, eventually taking the alias Gabriel.

Reception
In 2020, CBR.com ranked Blackheart 6th in their "10 Most Powerful Comic Book Villains With Demonic Origins" list.
Blackheart appears in Ghost Rider (2007), portrayed by Wes Bentley. This version primarily assumes and maintains a human form with pale skin and black hair, though he displays traces of his demonic facial features at varying points in the film. Additionally, he is stated to have all of his father, Mephistopheles', powers along with a "lethal touch" that he can use to kill people, an immunity to holy objects and places since he was born in hell, and no soul, which makes him immune to the Ghost Rider's Penance Stare. Blackheart seeks to obtain the Contract of San Venganza, which grants its owner access to the power of a thousand evil souls. Upon learning of his son's search, Mephistopheles transforms Johnny Blaze into the Ghost Rider and tasks him with killing Blackheart. Despite Blaze's efforts, Blackheart succeeds in obtaining the contract and fuses with the souls to become Legion, gaining regenerative capabilities in the process. However, the souls make him susceptible to the Penance Stare, which Blaze exploits to kill Blackheart.
Blackheart appears in the Ghost Rider film tie-in game, voiced by Robin Atkin Downes. This version can shapeshift into his film and comic book incarnations' appearances.

Of course, he has basics like super strength and speed, but he can also alter his appearance, travel between dimensions, telekinesis, telepathy, and even dispel blasts of energy from his hands. On top of all of that, Blackheart is wildly intelligent as well.
