Devack, known as Demak (ディマク, Dimaku) is an opponent in Yu-Gi-Oh! 5D's Duel Transer. This is a video game depiction of Devack, a character from the Yu-Gi-Oh! 5D's anime.
Devack is located on Bifrost 4F. The path to him is locked, and the player cannot reach his location unless they have a "Earthbound Immortal Cusillu" card. Beating him unlocks his Deck Recipe at the card shop and enables the player to continue Dueling him in Free Duels.
