Captain Marvel
From Superdickery
A superhero that is imbued with the powers of six gods (Solomon, Hercules, Atlas, Zeus, Achilles and Mercury) by the wizard Shazam.
This is the only Captain Marvel. Anyone who disagrees can go die in a fire.
Despite being a creature of magic, he seems to be beaten by Superman regularly. This is due to the fact that DC wouldn't dare let anyone, short of a prep-time-adequate Batman, defeat Superman.
