Batman:The Animated Series Wiki

Joker Fish were fishes with the Joker's features.


They were once regular fish, but were infected with Joker Venom, causing their mouths to be stretched into a smile and their skin turned white, a crew of fishermen were catching fish when they came across the Joker Fish and were disgusted at what they were seeing, Joker then tried to copyright them but was unsuccessful as the man at the desk told him that fish were a natural resource and nobody could copyright natural resources.

Joker also made a commercial for them on TV, along with Harley Quinn and his henchmen.


  • The Laughing Fish was inspired by issue 475 of Detective Comics where a very similar plot to the one in the episode plays out.
