Isis is a villain character in Krypto the Superdog


She is Catwoman's pet cat and is a enemy of Ace the Bathound and Krypto the Superdog. She's also fought Streaky, Jimmy the Rat, and Robbie the Bird Wonder. She once teamed with Bud and Lou and Mechanikat. It seems Isis and Ace have the same "relationship" as their owners.
