Shin Megami Tensei: Devil Summoner: Raidou Kuzunoha vs. The Soulless Army
Simply named "player", two prototype 3D models of Kyouji Kuzunoha from Shin Megami Tensei: Devil Summoner can be found in the game's files. Not only has Kyouji never appeared in a 3D game, but his particular appearance here is only ever seen in Devil Summoner and its concept art. Additionally, this is before Kyouji's body has been possessed, since his possessed form features an entirely different hairstyle. The black-suited Kyouji model comes with a number of textured weapons and unique attack and death animations that can be viewed through the game's debug menu, suggesting that he was originally planned to be a playable character.
