Los Angeles ? The Walt Disney Co. is punching its way into the universe of superheroes and their male fans with a deal announced Monday to acquire Marvel Entertainment Inc. for $4 billion, bringing characters such as Iron Man and Spider-Man into the family of Mickey Mouse and “Toy Story.”

The surprise cash-and-stock deal sent Spidey senses tingling in the comic book world. It could lead to new rides, movies, action figures and other outlets for Marvel’s 5,000 characters, although Marvel already was aggressively licensing its properties for such uses.

The deal won’t have benefits right away, and Disney stock sank on the news. Disney expects a short-term profit hit, and Marvel characters from X-Men to Daredevil are locked up in deals with other movie studios and theme parks. But Disney’s CEO, Robert Iger, promised an action-packed future.
