10 Dumbest Batman Moments You Won't Believe
5. Killer Whale Yacht Robber - Batman #579
Issue 579 focuses on a villain that is obscure and dumb enough to have joined the ranks of other silly villains like Condiment king and Killer Moth in the Lego Batman Movie. After an orca shaped villain called Orca starts pirate-style robbing the wealthy during yacht parties, Batman decides to research at the Gotham aquarium.
It turns out that Dr. Grace Balin, who assists Batman in his killer whale-based inquiries, is also secretly Orca. Despite not having anyone to verify her alibi Batman doesn't think she could be the one committing the crimes (not because she in no way resembles a killer whale but because she uses a wheel chair).
This issue is pretty boilerplate stupid, the thing that pushes it over the edge is the artwork. The otherwise only vaguely-humanoid killer-whale-shaped villain has tatas larger than Batman's head. They are so massive and strategically on display in every panel that it adds an extra dose of dumb to Orca's battle with Batman.
