Robzarro was created by Patrick Gleason and Peter J. Tomasi. He made his first appearance in Bizarroverse part 2.
Robzarro is searching for his friend, Boyzarro. He finds him joined by Jon, Maya and Kathy. It seems that he's quite the casa nova, quickly finding himself trying to impress Maya. Unfortunately for him, he's not her type.
Due to the destruction of his home planet Htrae, he's now living on planet earth.
