New X-Men (2004)

Choosing Sides part 1 of 6
For the young mutants at the Xavier Institute, life will never be the same! The children at the X-Mansion thought they had it tough when Professor X was running things... but now that X-Men Cyclops and Emma Frost have taken over the reins of the school, they're wishing for the simpler times of yesterday! Codenames, school-issued uniforms and mandatory training sessions in the Danger Room are just a few of the changes being implemented around the Institute... but when the entire student body is forced to divide itself up into small squads and "choose sides," Xavier's will never be the same again!
