Reiji Oyama (大山 礼児, Ōyama Reiji) is one of the characters designed for the series, making his first appearance in Power Instinct and has been a recurring character since. He is somewhat of a parody of Ryu from the Street Fighter series. In this sense, he could also be considered a parody of the characters who are very much like Ryu in personality. Reiji was voiced by Kijitani Toshiyuki in CR Goketsuji Ichizoku.
