Legendary comic book creator Stan Lee is the master of film cameos, and no stranger to video game appearances either, but it's not enough. He needs to be in every video game, from Duck Hunt to The Legend of Zelda.
I'm not sure how involved Stan Lee really is with the Stan Lee's World of Heroes YouTube channel, but I like to think he personally handpicked each of the games in this video. He probably likes to think that too. Heck, he probably made most of them.
