Today they are X-Men, protectors of humanity and the vanguard of mutantkind. But before they became heroes, they were just teenagers – frightened of a world that feared and hated them. Adolescence is never easy but it’s even harder when you find yourself with incredible abilities you can barely understand, much less control. Take a look back at how some of your favorite mutants fought their way through childhood to become X-Men. Collecting X-MEN ORIGINS: CYCLOPS, NIGHTCRAWLER, ICEMAN, EMMA FROST and DEADPOOL, plus bonus material from GIANT-SIZE X-MEN #1 and X-MEN (1963) #131.
