Dark Bunny is a superhero who stars in an animated television series.
Although first said to be cousins, it is later revealed that he and Bionic Bunny are twin brothers. When Bionic Bunny and Dark Bunny were born, the two were separated at birth. Dark Bunny was taken by a witch and Bionic Bunny was taken by a robot.
Although the Dark Bunny show did not start until "That's a Baby Show!" the episode "Double Dare" reveals that the superhero poster in the Tree House (which has been there since Season 1) is of Dark Bunny.
- He is a parody of the DC Comics superhero, Batman, similar to his brother being a parody of Superman. Additionally, Dark City is a parody of Batman's hometown of Gotham City. Likewise, some of the members of his rogues gallery resemble those of Batman's.
- In some episodes, he is said to be evil, although in others, he is a super hero.
- His civilian identity is a parody of Batman's as Dark Bunny's true identity is Deuce Dwayne which rhymes with Bruce Wayne (Batman's true identity).
