Mutates are humans who undergo an artificial mutation.
As a major proponent of the Mutant Registration Act, Senator Kelly is kidnapped by the Brotherhood of Mutants and brought to the island of Genosha. There, Magneto used a machine to expose Senator Kelly to radiation, thus triggering a mutation. Using his newfound abilities, Senator Kelly escaped Genosha and arrived at the X-Mansion, seeking help from Dr. Jean Grey.
From reading Senator Kelly's mind, Professor X learned that Magneto intended to use his machine to transform all the world leaders present at the World Summit into mutates, so that they would share the persecution that mutants face in society. However, because of the unstable nature of these mutations, anyone exposed to the machine's radiation would be harmed. This was proven when Senator Kelly dies shortly afterwards, his body disintegrating into a liquid state.
The X-Men went to Liberty Island, where Magneto was holding Rogue after kidnapping her. Through her ability to absorb mutant powers, Rogue unwillingly received Magneto's powers and powers the machine. As the radiation was about to reach the World Summit, however, Wolverine managed to destroy the machine with help from the X-Men, saving the lives of the world leaders.
After being diagnosed with terminal cancer, Wade Wilson was recruited by Agent Smith to take part in an experimental program that would cure him of his cancer and make him superhuman. After agreeing to join the program, Wade learned that it was in fact a covert organisation creating super soldiers and selling them off to the highest bidder. After he was subjected to extreme physical torture, Wade's mutant genes were unlocked and altered his outward appearance grotesquely. He managed to escape captivity and set the workshop ablaze, thus temporarily halting the program's production of mutates.
With enhanced healing abilities, Wade donned a costume and became a mercenary known as "Deadpool". He hunted down associates of Ajax, the man responsible for operating the program that triggered his mutation. Through Agent Smith, Deadpool learned of Ajax's whereabouts and slaughtered many of his associates to get to him. Unfortunately, the intervention of Colossus and Negasonic Teenage Warhead prevented him from killing Ajax.
After recuperating, Ajax and his partner - Angel Dust - kidnapped Deadpool's former lover, Vanessa, in an attempt to lure him out. Enlisting the help of Colossus and Negasonic Teenage Warhead, Deadpool battled Ajax's forces to rescue Vanessa. The fight ended with Deadpool shooting Ajax in the head after Negasonic Teenage Warhead's powers reduced the aircraft they fought on to rubble. With Ajax's death, the mutate creation program was seemingly disbanded.
