Upstarts and Acolytes

Cortez was bored with his life, even though he was wealthy and had high social status. He joined the Upstarts for excitement, a group of mutants organized by the Gamesmaster who were awarded points for killing other mutants. Cortez gathered a group of mutants who believed in Magneto's teachings and formed the Acolytes. He brought the group to Asteroid M, Magneto's orbital base, only to arrange for its destruction and the death of the first wave of Acolytes along with their messiah.[citation needed]

Obtaining many points for the deaths of such powerful mutants, Cortez then gathered a second group of Acolytes easily by playing Magneto off as a martyr. Neophyte overheard Cortez telling the Gamesmaster about how he killed Magneto and caused the other Acolytes to abandon him.[citation needed]

When Magneto returned and was mind-wiped, the Gamesmaster stripped Cortez of his points. Furious, Fabian concocted an elaborate scheme to regain them. He kidnapped Luna Maximoff, the daughter of Quicksilver and granddaughter of Magneto, and began a civil war on Genosha by encouraging mutates to kill the ruling humans. Both the X-Men and the Avengers tried to stop him, and he was apparently killed by the new Acolyte leader Exodus.[citation needed]

Cortez resurfaced months later when Joseph assumed control of the Acolytes. Pretending to help Joseph assume Magneto's leadership role, his schemes were again unveiled. He then tried to destroy the X-Men with another wave of Acolytes, but eventually abandoned his own allies.[citation needed]

Later when Magneto was returned to his full mental capacity, he gave Cortez a chance to redeem himself. Weakened by trying to manipulate the Earth's magnetic field, Magneto needed Cortez's powers to keep him rejuvenated. Magneto offered Cortez a place on the Genoshan cabinet, which he accepted. When Magneto attempted to obtain technology from Carrion Cove that would return his power levels to normal, Cortez betrayed him and helped the United Nations by augmenting rogue Acolytes to fight Magneto and his mutate army. His power levels faded during the battle for Carrion Cove, while Magneto returned to full power. Magneto finally got his revenge and used his new strength to repel Cortez fifty miles and smash him into the ground; he died on impact.[citation needed]


Cortez was resurrected via the Transmode Virus during the Necrosha crisis and, searching for Magneto with his fellow acolytes Delgado and Mellencamp, battled Deadpool and Loa. They were eventually, and contrary to the others "zombies" who weren't possible to kill, killed by Loa's powers (Loa was used as a projectile by Deadpool).[2]

Upstarts v. X-Men v. O.N.E.

Cortez reappeared once again as a member of the mutant group the Upstarts. He helped kill the Nasty Boys in order to lure out Cyclops and his ragtag team of X-Men to Washington Heights. After a brief moment of words, the two groups engaged each other in battle. Cortez faced off against Hope Summers and the Juggernaut but became overwhelmed as they were outnumbered. He fled the scene with Siena Blaze and Fitzroy leaving Shaw behind as a scapegoat.[3]

He was the last of the Upstarts alive. The X-Men bailed him out to help. He used his powers to help the Black Queen remove mutants from the minds of every person.[4] It was revealed that O*N*E had not forgotten about mutants. Their sentinel squad came and started attacking. After many casualties, they shot and vaporized Cortez into nothing, which killed him.[5]

House of X

Cortez was later seen resurrected and well among Exodus and other Acolytes when they were first greeted by a hologram of Professor X, then later when they were seen on Krakoa among other X-Men villains and foes. As Professor X's hologram was conversing with them, around the world he was also greeting and conversing with other mutants, welcoming them into the country of Krakoa.[6]


Power Augmentation Manipulation: Cortez had the ability to augment the powers of other mutants, often to dangerous levels. Cortez could also use his power to read genetic code and harm other mutants while appearing to heal them. He may also have had some control over his own power's energy field, possibly being able to constrict it around a foe.


Fabian was an experienced leader and a skilled martial artist.

Strength level

Cortez possessed the normal human strength of a man of his age, height, and build who engaged in intensive regular exercise.
