Also known as: アッシュ・クリムゾン
The third "Hero" from SNK in their King of Fighters series. He isn't much of a hero though, his main mission is to steal the three sacred treasures of Japan for himself. He was designed to be an "ambiguous, lovably evil main character", hence the Androgynous or Trap tags.
He is voiced by Nagashiro Sounosuke [長代 聡之介].
