The Caped Cod is a demented homicidal cod who proclaims himself as ruler of the sea. Delusionally, he believes garbage items are his royal subjects. He first appeared in The Dog Who Cried Fish. When he first saw Dudley he paranoidly thought he was the king of land because of the toy crown he was wearing. Suspicious, he battled him for his "kingdom" and lost, then tried to flood the city but got captured in the end. Jailed in a clam at the Petropolis Aquarium for the criminally insane, he vowed revenge on Dudley. In Doom and Gloom, he was seen inside a fishbowl at Petropolis Prison. It could be possible that he was temporarily transferred there. In Cold Fish, he escaped and tried to flood Petropolis again in order to make it part of his kingdom by melting the Riceberg Ice Bird Iceberg, in which he now has a sidekick named the Seal of Approval. He also did this to get revenge on Bryce Riceberg because she didn't invite him to her wedding and they were best friends in middle school. He was once again stopped. He is voiced by Chris Parnell in The Dog Who Cried Fish and Mick Wingert in Cold Fish.
