SHAZAM! The original Captain Marvel. He is totally awesome. The magic adult version of Billy Batson a good kid with a good heart....this is the worlds most powerful boy scout...equal in power to Superman just about.
Captain Marvel made his first appearance in Fawcett's Whiz Comics #2. Captain Marvel's rights were later sold to DC and he is now known as "Shazam" since Marvel has a female character known as "Captain Marvel". Go figure.
