i'm a great big fan of Joe Stone's instant classic X-Men Family Tree, and I thought I'd use it to map out the missed intricancies of the X-Men's incestuous lives through the characters' appearances in the X-Men film franchise.
there's 5 markers under each character, for the five X-movies. in order: X-Men, X2: X-Men United, X-Men: Last Stand, X-Men Origins: Wolverine and X-Men First Class. a lowercase letter indicates cameo appearances. fun with OCD!
