Yahoo is reporting that Disney is set to buy Marvel and all its Characters.

The Walt Disney Co. said Monday it is buying Marvel Entertainment Inc. for $4 billion in cash and stock, bringing characters like Iron Man and Spider-Man into the family of Mickey Mouse and WALL-E.

Under the deal, Disney will acquire ownership of 5,000 Marvel characters. Many of them, including the Fantastic Four and the X-Men, were co-created by the comic book legend Stan Lee.
