Robot Acrobat

The unnamed Robot Acrobat works in Circus Roboticus under Fishy Joe and is assumably a Robo-Hungarian immigrant in New New York. Nonchalanto accidentally shot him while performing a trick for Fishy Joe. What happened to him afterwards is unknown.

Trivia

 * In "The Prisoner of Benda", the episode in which he debuted, we didn't have a chance to hear his voice or even see his face.
