This is the team that started it all. Five teen mutants (Angel, Beast, Cyclops, Iceman and Marvel Girl) were brought together by Professor Charles Xavier in order to learn about their powers and protect the world from mutants who would use their powers to harm others. As time passed their rota has expanded and changed, the founding members are no longer teens but adults. There has been many teams to carry the X - X-Factor, X-Force, Excalibur, Generation X, X-Statix. The Xavier Institute has returned to being a school for young mutants but is also home to a field team, the X-Men which exists to 'protect a world that fears and hates them'. Among it's former members are Jubilee, Banshee and Cannonball (Husk's older brother).
