Gigaros

Gigaros was a male Cardian who appeared in episode 052. Ail and An realized that they were quickly running out of energy, so An suggested that this time they try to steal younger and "fresher" energy than before, so they called forth Gigaros. He immediately went to work attacking busses full of children and stealing their energy, beginning with students from Kari Kindergarten. Gigaros's name is a pun on the Japanese spelling of the name Icarus. Icarus was a character in Greek mythology who had man-made wings created with wax. In the well-known tale, Icarus soared too close to the sun and his waxen wings melted, causing him to fall into the sea and die.

Gigaros's outfit - a toga-like garb with large wings - reflects his namesake.
