Mickey Mouse is one step closer to getting super powers.
Marvel -- famous for characters such Spider Man, Iron Man, the X-Men and the Fantastic Four -- would bring its army of more than 5,000 characters to the Disney balance sheets.
Disney already owns Pixar, the Emeryville, Calif.-based studio well-known for its computer-animated films like Toy Story and Wall-E.
While Pixar movies appeal to young children and parents and Disney's traditional fare appeals to tweens and teenage girls, Marvel's characters are popular with teenage boys, filling out a weak spot in Disney's lineup.
Based on the closing price of Disney's common stock, the merger is valued at $4.3 billion, according to Marvel.
The deal was expected to be completed after the close of the market Thursday.
