History of character has not yet been written.


  • This version of Bart Regan, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
  • Bart Regan's first published appearance was in Comics Magazine #2 June 1936, published by Centaur Publications. The feature did not return in issue #3 of that title, and its second appearance was in Detective Comics #1, published by Detective Comics, Inc.
