1. "Challengers Of The Fantastic"
In one of the more unusual Marvel/DC crossovers, the heroes from both worlds were combined to create new creations which borrowed elements from both. The Challengers of the Fantastic were a mashup of the Fantastic Four and obscure team Challengers of the Unknown, although it seems like the DC group was only chosen because they also had four members! Their foes included Multi-Masters, Galactiac and of course, Doctor Doomsday. What other crazy Fantastic Four facts do you know? Share them down in the comments.
