Feral (Maria Callasantos) is a fictional character appearing in American comic books published by Marvel Comics. She has been both a superhero and a supervillain and most recognizably associated as a member of X-Force. Feral is the sister of Thornn. Publication history Feral first appeared in The New Mutants #99 (March 1991), and was created by Rob Liefeld and Fabian Nicieza. Fictional character biography The cat-like mutant Feral attempted to escape from the tyrannical rule of the Morlock, Masque. She was saved from Masque by Cable, and agreed to join Cable's paramilitary group X-Force in return for protection. Alongside X-Force, she first battled the Mutant Liberation Front, during which she broke Wildside's jaw. She then severely injured Cannonball during combat training. She fought her sister Thornn, when Thornn and Masque invaded X-Force Base. She next battled Sauron. Alongside X-Force, she battled Weapon P.R.I.M.E. She was later compelled by the Druid to go to Starkesboro, Massachusetts. During the X-Cutioner's Song saga, she was attacked by the X-Men and X-Factor alongside X-Force. She was captured by Wolverine, and was taken prisoner with X-Force by the X-Men and X-Factor. Feral later received a new costume, and left Xavier's mansion with the rest of X-Force. With X-Force, she then fought Nick Fury and War Machine. Feral was always the ticking time bomb of X-Force especially when it came to teammate Siryn, barely capable of controlling her deadly temper. Prior to joining the group, it was later revealed that Maria and her sister Lucia (who later became known as Thornn) had to leave home and lived with the Morlocks. It was later discovered that both girls had been abused by their cocaine addict stepfather; in retaliation, Feral killed the man and shoved his body into the wall. Her mother, who was also addicted to cocaine, found out and sought vengeance on the girl by killing all of her pet pigeons. This infuriated Feral to the point where she also killed her mother in a fit of rage. It was also hinted that she purposely pushed their younger sister down the stairs, leading to her death, as well as allowed their younger brother to fall to his death from their roof. Ultimately, Feral betrayed X-Force and became the enemy of her former teammates when she was convinced to join the terrorist group known as the Mutant Liberation Front, although her alliances would continue to shift.
