While DC seemed to focus on the Greek gods in Wonder Woman, Marvel decided to create a series of stories based upon the Norse gods. Thor and his fellow Norse gods debuted in August of 1962 and although they're not currently in a series, they are slated to return in the Summer of 2007.
Heimdall is the sentry that guards the Rainbow Bridge that provides access to the Asgard, the home of the Norse gods. However, Heimdall's main claim to fame is being the only Norse God to sport the Abraham Lincoln – Chin Curtain beard.
