Grösshorn Eule was a Nazi and member of Axis Amerika. He battled against the Young All-Stars on several occasions during World War II. During a battle in California, his son and sidekick, Fledermaus, was killed by Fury.[1] His actions since the war are undocumented.


  • Grösshorn Eule was created as a villainous counterpart to the now-vanished Earth-Two/Golden Age Batman, who was erased from post-Crisis history.
  • "Grösshorn Eule" is a literal German translation of "Great Horned Owl", and "Fledermaus" (the name of his sidekick) is German for "bat".
