>The X-Men (1998).
Written by Michael Chabon.
Professor Charles Xavier creates the X-Men -- Cyclops, Jean Grey, Iceman, Beast, Storm and Nightcrawler -- to fight for the pacific co-existence between humans and mutants. Fearing that the extremist Mutant Liberation Front might retaliate against the human race after the Mutant Registration Act is created in response to the X-Men's attempts to recruit young runaway mutants, The Council of Elders forbids the X-Men from further helping others. Nevertheless, an e-mail Best receives from his mentor, Dr. Harold Lee, leads the group to rescue Wolverine, who was being hunted by the White Farm, a paramilitary unit affiliated with Department H. The team also rescues Lee's daughter, Jubilee, who was being monitored by spies impersonating her parents.
A confrontation with the White Farm reveals that Wolverine has been made into a carrier for the Legacy Virus, which infects Jean Grey and Iceman. Exiled by the X-Men, who view him as a liability, Wolverine then decides to go after the White Farm alone, though Jubilee soon joins him, followed by the X-Men themselves. Together, they learn Jubilee's parents created the Legacy Virus and bonded Adamantium to his skeleton on behalf of the League of Gentlemen, a secret society controlled by Mr. Montcleaf, who rules the word in secret for centuries, and wants to destroy mutants. Upon learning that their daughter was a mutant, and had been selected by Montcleaf as the next subject of the Weapon X Program, the Lees instead encoded a cure for the Legacy Virus in her DNA and allowed Wolverine to escape after embedding in his mind paternal feelings towards Jubilee to ensure her safety, not knowing that Wolverine had been infected with the Legacy Virus.
By dismantling the Weapon X Program, Wolverine and Jubilee earn their place in the X-Men, and motivate Xavier to go against The Council's wishes and reveal himself and his team to the world in an effort to build trust between humans and mutants.
