The third movie in theX-Men series involves someone finding a "cure" for mutant genes, causing Magneto to start recruiting for a mutant uprising. Also, Jean Greygets better (guys,It Was His Sled!), but evidentlyCame Back Wrong, because now she can kill you with her brain. Rogue takes the cure voluntarily, on grounds that sheCan't Have Sex Ever. The X-Men move to defend the cure-making facility from Magneto's forces, and eventually "cure" him, which puts an end to his crusade. Unfortunately, Jean staysAx Crazy, so Wolverine has to kill her, after which he returns to the Xavier Mansion to help Storm lead the next generation of X-Men.
