Ace

Ace is Batman's loyal canine companion in the all-ages Tiny Titans universe, an ordinary dog occasionally outfitted with a Bat-Utility-Belt. He runs with the Super Pets and the broader Batman Family, holding his own among Gotham's finest despite having no superpowers whatsoever.

Bounding onto the scene in 2009's Tiny Titans #13, Ace is a Modern Age DC character with an enviable address book — sharing pages with Batman, Robin, Batgirl, Dick Grayson, and Alfred Pennyworth across some of the most storied titles in comics, including Detective Comics and Batman themselves. Debuting in Art Baltazar and Franco's beloved all-ages gem, Ace has proven surprisingly durable, with appearances stretching across sixteen years and into the mid-2020s. It's a testament to the character's charm that a Tiny Titans alumnus can hold their own alongside the heaviest hitters in Gotham's world.
