  • Marvel Comics owns the trademark for the name Captain Marvel. DC comics owns trademarks for the names Shazam and Billy Batson, and Mary Marvel. In order to use Captain Marvel's name it must be used in the interior of the story, the same way DC does to avoid Marvel's trademark on the name.
  • Only the golden age version of Mary Marvel (as depicted in the comics that fell into public domain) is public domain. Non-public domain Golden Age appearances are under copyright of DC Comics, which owns the version of the character based on those comics and all subsequent versions published under DC comics banner such as her white costume which first appeared in the Power of Shazam! #28 .
