Catman was originally a world famous jungle cat trapper and a millionaire named Thomas Blake. He had grown bored with hunting and wealth and decided to become a supervillain for excitement. He was inspired by both Batman and Catwoman in his design. He was a thief with a cat theme like her, but his costume and utility belt was reminiscent of Batman. Catwoman, not liking her modus operandi stolen worked with Batman to capture Blake.
He returned on another crime spree claiming his cape was now enchanted and gave him 9 lives. Batman and Batwoman destroyed the cape, causing him to act cowardly and surrender. He would later enter a criminal partnership with Catwoman, however she found his sexist attitudes annoying and helped capture him. He would later be a member of a supervillain team called the Misfits, but was defeated again. Later the South Sea cat cult, the group he stole the magic cape from, wanted it back. Catwoman gave them a fake to spare Catman's life. Many years later he became a foe of Green Arrow, but was now overweight and became a disrespected loser. After hitting rock bottom he went back to Africa and lived among a pack of lions. He regains his physical form and confidence among them. When the Secret Society of Supervillains tries to recruit him he refuses, and they kill the lion pack as revenge for refusing them. Catman joined a team called the Secret Six, who fought the Secret Society. However he learned that Deadshot killed the pack so Catman would join the Secret Six. Catman ultimately forgave him. After this he became somewhat of an antihero rather then villain. He also had a child with Chesure called Thomas Jr. After more adventures he became the leader of Secret Six and tried to break Tarantula out of Alcatraz. He actually managed to fight Batman to a standstill while the rest of the six escaped with Tarantula.
- Ironically Adam West's Catman alter Ego from Fairly Odd Parents is similar to the DC Catman and yet has similarities to Batman rather than Catman.
