Abra Kadabra is tall and thin. His black hair is styled in a ponytail with sideburns and a goatee beard. He has a narrow face and brown eyes. He typically wears a poet shirt that exposes his hairy chest and gold necklace, accompanied by black trousers over black briefs, black gloves, and a gold belt buckle with a letter A on it. He also wears an earring in his right ear.
Initially unbeknownst to everyone, Abra Kadabra came from an unspecific era from the future. At some unknown point, he traveled to the past, sporting technology so advanced that it passed off as magic.
Kadabra eventually clashed with Flash, who proved that the former used science from the future to simulate magic.He joined forces with Klarion in the hopes of gaining real magical powers.
After waiting outside the Tower of Fate for three weeks, Klarion and Abra followed the Team inside, as they had the key. Abra Kadabra engaged the Team whilst Klarion went after Kid Flash and the Helmet of Fate, and demonstrated surprising ability, able to incapacitate the entire team to the point they needed help from Doctor Fate, who teleported his clothing and equipment away after Klarion fled from their battle, giving Superboy the opportunity to defeat him.
In the comics, Abra is a member of the Rogues, and is one of the members who killed Bart Allen (the fourth Flash).
This is Abra's third animated appearance; he had a cameo in the Justice League Unlimited episode, "Flash and Substance", and appeared in two episodes of Batman: The Brave and the Bold. Jeff Bennet also played Kadabra there, but according to Greg Weisman, his reprisal was not deliberate.
