Full list of appearances
Black Knight BullBlack (黒騎士ブルブラック, Kuro Kishi BuruBurakku) (18-25). The previous Black Knight was a vengeful warrior. He is an ally to the Gingamen.
His original goal is to find Lights of Ginga, so he could take revenge on Captain Zahab. But his means are very selfish, as he does not care about hurting innocent humans to reach his goal, unlike the Gingamen.
But later it was revealed that he had fallen one thousand years earlier in the same abyss as Hyuuga, and that BullBlack uses the man's body to escape the abyss and fight again. This revelation came up when Hyuuga begins to stop him from using techniques that would hurt humans.
After Krantz's spirit begged him to stop hurting people, BullBlack releases Hyuuga and is killed to save the Gingamen from a hate energy explosion. His spirit found peace after reuniting with Krantz. Later, they appear (as spirits) to invest Hyuuga with BullBlack's powers by giving him the BullRiot Sword.
