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 debuted in Batman #92 (cover-dated July 1955). Ace's creation was inspired by the success of Krypto's debut in Adventure Comics #210 (March 1955), and by German Shepherd Dogs from detective films and serials, such as Rin Tin Tin and Ace the Wonder Dog. He was created by writer Bill Finger and artist Sheldon Moldoff.
Fictional character biography 
Ace was a German Shepherd Dog originally owned by an engraver named John Wilker. He was found by Batman and Robin after his master was kidnapped by a gang of counterfeiters. Batman used Ace to try to locate Wilker. Because he had already placed a large number of "lost dog" announcements for Ace in his civilian identity of Bruce Wayne, he was concerned that anyone recognizing Ace (who had a prominent star-shaped marking on his forehead) might make the connection between Bruce Wayne and Batman. To forestall that problem, he hastily improvised a hood-like mask for the dog that incorporated the bat emblem as a dog tag dangling from Ace's collar. Ace was subsequently christened "The Bat-Hound" by a criminal he helped Batman to apprehend.
Wilker later took a new job that made it difficult for him to take care of Ace, so he left the dog to Bruce Wayne. Wilker was never aware that Ace was the Bat-Hound or that Bruce Wayne was Batman.
At one point, Ace acquired super-powers thanks to Bat-Mite but this was short-lived. He did have his own training. For example; his specialized radio collar, when activated told him to don his own mask (via a hands-free device) and track down Batman and Robin.
A modern-day version of Ace was reintroduced in Batman #462 (June 1991), although he has been rarely seen in recent years. This version was originally a guide dog belonging to a blind Native American named Black Wolf, who called him "Dog". The dog assisted Batman in fighting criminals from Black Wolf's tribe. Following Black Wolf's death, Batman adopted Dog, renaming him Ace.
He did not wear a mask, nor was he ever referred to as Bat-Hound, and has the appearance of a beagle-pug crossbreed (which exists in the real world as a puggle) with a bat-shaped dark patch on his flank. Ace has at times helped Batman on cases  and is depicted to be very affectionate towards his owner and vice-versa.
After Batman is disabled by the villain Bane, Azrael takes over the role and ejects Ace, Nightwing, Robin and Harold Allnut from the Batcaves. Harold, a trusted confidante of Batman, takes in Ace; the live in a part of the caverns Azrael is unfamiliar with. To keep busy, Ace enjoys playing with a robotic mouse built by Harold.
A traditional Ace was seen in Final Crisis: Superman Beyond 3D. He is in limbo with other "forgotten characters", such as Gunfire, Geist, Hardhat of the Demolition Team and Merry Man of the Inferior Five. Merry Man explains everyone is here where no stories exist because nobody is writing about them. Despite this, Superman and his allies work to rescue all the residents of Limbo, who then help assist in the battle against the cosmic threat of Mandrakk.
The original Ace appeared in a flashback scene in Batman Inc. #4, thus making the current canon status of the Post-Crisis Ace unclear. In this story, Ace is trying to play with Robin who is fuming over Kathy Kane, Batwoman, and her influence on Batman. 
The New 52 
In Batman and Robin Vol 1: Born to Kill, Bruce is seen purchasing a black Great Dane from a kennel. He later gives this dog to his son Damian who names him Titus, though writer Peter Tomasi stated in an interview that he considered naming the dog Ace.
Other versions 
In Mark Waid's and Alex Ross's Kingdom Come miniseries, Ace is portrayed as the giant winged steed of the Fourth World Batwoman. Ace is also mentioned in Howard Chaykin's Batman/Houdini crossover. During a seance attended by Bruce Wayne and mystic debunker Harry Houdini, Ace was referred to as Bruce Wayne's childhood pet. In the Frankenstein pastiche Castle of the Bat, Dr Bruce Wayne tests his theories by creating a literal Bat-Hound: a dog with some of the attributes of a bat. A version of Ace appears in multiple issues of Tiny Titans, a comic created for younger readers.
In other media 
- In the late 1990s animated series Batman Beyond, Bruce Wayne had a pet/guard dog named Ace (vocal effects done by Frank Welker) that's a Great Dane mix. He made his first appearance the series premiere episode "Rebirth" as a fiercely loyal pet to his aged master. At first, Ace did not like Terry McGinnis. But after he and Terry were able to help each other on several missions, Terry earned Ace's affection and loyalty. The episode "Splicers", Terry briefly reflecting that Ace's loyalty was one of the 'small rewards' that he had gained in his time as Batman. Later, the episode "Ace in the Hole" revealed that Ace was a puppy that was bought from a pet store by illegal dog-fighting ring leader Ronnie Boxer but Ace managed to escape this abusive, violent life. He soon found Bruce (a fellow tormented soul) at Crime Alley during the anniversary of his parents' murders. After Ace was injured by a Jokerz member during an attempt to save Bruce from the thug, Bruce took Ace to a veterinary emergency hospital. Since there was no one to claim Ace and both the elder man and the dog desired companionship, Bruce took him in as his owner. After encountering Boxer, Ace and Terry stop Boxer's attempt to use synthetic growth hormones to turn his dogs into monsters. Ace plays a role in the movie Batman Beyond: Return of the Joker when he attacked the Joker in the movie's climax, damaged the controls for the Joker's new satellite weapon system, and freeing Batman (Terry) from his captivity. In the movie Batman: Mystery of the Batwoman, Ace was alluded when Robin (Tim Drake) commented that a dog could help the duo "sniff out clues". The Justice League Unlimited episode "Epilogue" suggested that the dog Ace might be named after the Ace from an early incarnation of the Royal Flush Gang that Batman (Bruce) briefly befriended before her death.
- In the 2005 Cartoon Network animated series Krypto the Superdog that stars 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 crime-fighting 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 the The Batman animated series, Ace was alluded when Alfred Pennyworth remarks "Perhaps I should equip the Batcave with a doggie door, should Bat-Hound decide to join the gang." during Batgirl's introduction.
- Ace the Bat-Hound appears in the Batman: The Brave and the Bold with his vocal effects done by Dee Bradley Baker. In "Legends of the Dark Mite!", he helps Batman fight Catman and an endangered tiger he unleashes on Batman. Ace manages to corner Catman up a tree, and Batman rewards him with a bat shaped treat after getting him to heel. Ace is later seen in the main plot of the episode, as a guise Bat-Mite created. When Batman see two Aces, he knows something is wrong. At the end, Batman touches Ace's collar to see if he is a fake, but he's the real thing and tells Ace that he was just making sure. Ace makes an appearance in "The Siege of Starro! Part One" where he is seen when Batman contacts Booster Gold. In "The Plague of the Prototypes!", Ace is friends with Batman's prototype Bat-Robot, Proto, and encourages him to save Batman from Black Mask. Later, using his jet-pack, he helps Batman and Proto track down and deactivate Black Mask's bombs.
