As Byakuya, the Imposter appears very similar to the real one, having blond hair and bright blue eyes accompanied by rectangular, white-framed glasses. Their shirt appears to be the same one as the real Byakuya in the first game; however, "Byakuya" is very heavy set and wears a white dinner jacket, white slacks, and white dress shoes. The Ultimate Imposter's true personality is somewhat unclear because they spend most of their time mimicking someone else's behavior.
