Ace Haneda is a character from the anime Reideen the Superior, where he is portrayed as an adolescent male with brown eyes and blonde, ear-length hair. Originally from New York, Ace experienced a traumatic incident in which his girlfriend lost her life, an event that deeply affected him and ultimately led to his decision to return to Japan. Upon his arrival, he became involved with the central group fighting alongside the giant robot Reideen. He is established as the first of the Angels, a group of warriors, and his specific role is to pilot the mecha known as Reideen Condor. Ace is noted to be slightly younger than the character Reiko, and he occasionally assists her by helping to make decisions. He also has a prior connection to another character, Masato, as the two were part of the same group of friends in New York.
