It’s Batman’s dog, Ace the Bat-Hound:
This was drawn around the same time as the Batwoman and Bat-Girl pieces that I posted two weeks ago. If you haven’t guessed which character I’ll be posting on Friday, here’s a hint: he does wear short-pants sometimes, but he is not Robin. See ya Friday!
I honestly didn’t even know Batman had a dog! Awesome!
lol… you would expect him to have a bat, wouldn’t you?
