He opened up an tournament for Beybladers to play, but actually he has a group of his own called "Dark Nebula" and the strongest Beyblader. Ryuuga, has a fearsome beyblade to steal beybladers' happiness in playing to turn them into despair.
He is helping Ryuuga to get "food" to get his beyblade feed and make a dark and despaired Beyblade world. For those in Dark Nebula who lost in the tournament, they get "feed" by Ryuga's beyblade, so the fearsome aura from his beyblade is from the beyblader's despair who lost their beyblades.
His beyblade is Dark Wolf.
He reappeared in Metal Fight Beyblade 4D, who is one of the members behind Reborn of Nemesis.
