Mark is doing his homework in his room when the phone rings - it's his father, Omni-Man. He needs help with a mission; a "major baddie" coming to Earth and it is Mark's job to keep him from coming into the atmosphere. That leaves one question for Mark, how is he going to be able to breathe in space? It shouldn't be a problem. Omni-Man can hold his breath for two weeks, so Invincible should be OK for a couple of hours.
