Dr. Ziggurat

Dr. Ziggurat is the owner of HD Acadamy. He wears a long black suit, black pants and triangular spectacles. His face and hair resemble that of an Egyptian pharaoh. He installed the arrangment system that gave power to Zeo, Damian and Jack. When Zeo's Arrangment Index arose, he told him that his hospitalized friend Toby's life would be in danger if he did not win the battle with Masamune. Ziggurat watched in delight as Zeo finished Masamune. But after Damian and Jack lost to Gingka and Ryuga, he put Toby in the Arrangement System, erased his memory and Toby became the new blader Faust with the bey Basalt Horologium.

Trivia

 * He was created because Doji doesn't die in the manga and plays a important part. So Dr. Ziggurat was created to fill his rolls.
