Greiger, known as Bommer (ボマー, Bomā) in the Japanese version, is an opponent in Yu-Gi-Oh! 5D's Duel Transer. This is a video game depiction of Greiger, a character from the Yu-Gi-Oh! 5D's anime.
Greiger can be found on Bifrost 6F if you have an "Earthbound Immortal Chacu Challhua" card. Upon defeating him, he is unlocked as a Free Duel opponent and his Deck Recipe is unlocked as well, but due to it using 3 copies of "Dark Strike Fighter", it cannot be used by the player.
