Bat had short blond hair and green eyes. He wore a dark gray suit, gray pants, and black dress shoes. When he activated his android part, his left ear grew a scorpion tail-like appendix.
Bat has shown to be a liar and a coward. He acts mostly on his own whims.
Bat once hijacked a plane heading for an unknown destination, but was defeated by the team work of both Siesta and Kimihiko.
