Sort the X-Men in their Hogwarts Houses!
Where do you think they'd all belong?
Personally I'm all for Mystique in Slytherin. She's cunning and ambitious. Magneto though? Weirdly my impulse is Hufflepuff. They value hard work, dedication, patience, loyalty, and fair play- and that last one is one of his biggest motivators. Where would everyone else go though?
