Pledging his loyalty to Magneto, Cortez is disgusted by his willingness to host humans as guests on his sanctuary of Asteroid M and launches a missile at Earth. Upon being confronted by Magneto, Cortez attempts to kill him and [[FrameUp frames the X-Men]] for his apparent murder, setting himself up as the savior of mutantkind as he tortures Gambit and threatens to use Asteroid M's remaining missiles on nations across the world unless all mutants are freed. When his deceit is revealed, Cortez tries to launch the missiles anyway, and is saved from the crashing asteroid by Apocalypse. Gleefully becoming a [[PsychoSupporter devoted follower]] of the mad mutant, Cortez has mutant [[WouldHurtAChild children]] hunted in search of a vessel for his master's spirit; uses his energy-enhancing powers to painfully turn Beast into a savage animal; and attempts to sacrifice Jubilee to herald the cleansing of the weak and unfaithful from the world. While presenting himself as an enlightened freedom fighter resisting human tyranny, [[NotSoWellIntentionedExtremist Cortez]] in truth is nothing more than a raving, narcissistic egomaniac who would gladly wipe out anyone, human or mutant, whom he deems unworthy.

* [[EvilutionaryBiologist Herbert Landon]] is a [[FantasticRacism rabid anti-mutant extremist]] who created a formula that destroyed mutant cells and killed any mutant exposed to it. His endgame was to market this formula to the public as a cure for mutants only to instead use it to [[FinalSolution wipe them all out]]. The first person Landon attempted to test out this formula on is his "old friend", Hank "Beast" [=McCoy=]. Thwarted in this endeavor, Landon would go on to work for [[Characters/MarvelComicsTheKingpin the Kingpin]], and performed various unsavory deeds such as forcibly converting Alistair Smythe into a cyborg slave and testing out a SuperSoldier serum by using [[ClassyCatBurglar Felicia Hardy]] as a guinea pig.
