Shadou Yugi

Shadou Yugi, a.k.a. Dark Yuugi is a major antagonist in the anime Dark Game!, and a supporting antagonist in Spirit Chi Warriors!. He is the living essence of Yugi Typhoon's own "inner darkness," spawned from the part of Yugi containing his past life's essence, TsuYugi Typhoon. Shadou Yugi initially sought out to take control as the main host of the vessel that controls him. On occasions, he would challenge Yugi and his friends to intense Dark Games, where it gave him the opportunity to take full control by banishing Yugi to Hell, as well as wiping his mind clean of all positive thoughts. Shadou Yugi's ambitions eventually evolve, striving to set apart from Yugi, wanting to gain his own identity. Although he achieves this goal for a time being, he is eventually defeated by Yugi Typhoon in a Dark Game one last time, permanently sealing him into Yugi, until he is again released as the true form of TsuYugi.
