Net Worth: $3.5 billion
Running a mutant superhero team isn’t cheap, so it shouldn’t be much of a surprise that two X-Men leaders make the list. Professor Charles Xavier, the founder of the X-Men and Xavier’s School for Gifted Youngsters, is worth $3.5 billion; at least according to Fantomex, who tried to extort Xavier (New X-Men #129). You’d think the same person who can read everyone’s mind might have a little bit more money on hand (he’d only be #497 in the Forbes 500), but Xavier seems to have bigger priorities than acquiring cash.
