Doji

He was an enemy of Gingka Hagane and the former leader of Dark Nebula who had Ryuga. He used to own Dark Wolf DF145FS before it got broken. Doji seeked the power of the "Forbidden Bey", Lightning L-Drago 100HF.

Doji and Ryuga were the ones who invaded Koma Village, Gingka's hometown, and stole the Forbidden Bey Lightning L-Drago from it. Being the head of Dark Nebula, and having Ryuga on his side, he arranged the Battle Bladers tournament in order to give Ryuga more power so they could eventually rule the world. Doji is a person who never really gets serious even if his enemies were strong such as Gingka. He is also a person who doesn't like to show his real power, especially not to children such as Kenta. Doji is extremely cruel, often punishing members of the Dark Nebula by "feeding" their power to Lightning L-Drago 100HF when ever they fail at the task they are given. He is never one to give up on his goals and desires, as he uses his intellect to get ahead of his enemies. He always speaks in a polite manner, even to his enemies, but there's no mistaking the arrogance in what he says. He'll frequently access people as 'my friend' in a condescending manner. Generally, he appears to never accept people as being on his level. Yu Tendo used to be a member of the dark nebula he somehow manage to get away when reiji was destroying his bey. Doji will not give up on finding yu and stealing him as well as punishing him by using reiji to destroy his bey further. Doji also despises ryuga and gingka for ruining his plans Doji uses dark wolf Dark wolf's special moves: Darkness howling blazer dark wolf makes a black hole in the ground sucking you in and attacking you in there while your helpless.
