Kamen rider Gai from the Ryuki series (same one as that pink stingray guy). I love suit designs with a rhino aesthetic and this suit is probably my favourite steel rhino theme of all time. This series was unique as it introduced a monster tamer/card gimmick akin to the many fads at the time. Ryuki's riders, all destined to fight one another to the death, had unique card visors to produce special attacks. Gai's was on his left shoulder, which was a pleasant surprise for the viewer.
