These guys are so weird. I never quite understood them as villains, it's like someone said "Hey, what sort of evil team should the FF fight? Well, they're champions of science, why not make these guys magic? And our heroes have an alliterative numerical team name, we should do that. How about Frightful Four? No? Taken? Five's boring. Ok, what about Sinister Six? ALSO taken!? Huh. Alright, what's goes with Seven..."
