Ace the Bat-Hound

The comic book character Ace the Bat-Hound was the canine crime-fighting partner of Batman and Robin in DC Comics of the 1950s and 1960s.

Ace, as he appears in the 2005 cartoon series Krypto the Superdog.*In the 2005 Cartoon Network animated series Krypto the Superdog, starring Krypto, (Superman's childhood dog), Ace the Bat-Hound (voiced by Scott McNeil) makes occasional appearances and is once again a crimefighting ally of Batman—although the Dark Knight himself does not appear on the show. In this series, Ace, much like Batman, is equipped with various gadgets and equipment as an aid in his crimefighting efforts. In one episode, he met the Dog Star Patrol and helped them find their missing member Hot Dog. His enemies include The Joker's hyenas Bud and Lou, The Penguin's trained birds (Artie the Puffin, Griff the Vulture, and Waddles the Penguin), and Catwoman's pet cat Isis (who flirts with Ace much like Catwoman flirts with Batman). Ace has a Batwoman-style glider he uses for more speed. He considers himself to be Batman's partner, rather than his pet.

In Batman Beyond, he serves as the tetartagonist, and a pet to Bruce, and sometimes a watchdog with Terry, the new Batman.
