Combo Man

Rick Wilder is a superhero with the powers of various Marvel superheroes and villains including Wolverine, Punisher, Iron Man, Hulk, Captain America, Spider-Man, Daredevil, Human Torch, Doctor Doom, Magneto and Cyclops. Any awesomeness of this character was ruined by the fact he also happens to be an advertisement for the Combo snack food.
After seeing a teacher being threaten by A.I.M. (a group of scientists that make weapons terrorists especially HYDRA) agents, Rick Wilder ate a combo that turned him into Combo Man. He easily beat the A.I.M. agent, but they send the Super-Adaptiod on him. Of course, Combo Man defeats him. Unsurprising, Combo Man's comic, Combo Man, had only one issue.
