Dr. Ichigaki (Dr.イチガキ?) is an evil demon scientist from the spirit world intent on creating the ultimate fighting weapon. He dupes 3 martial artists into volunteering for an experiment, in exchange for curing their master of a deadly disease. He then implants his creation, the Blood-Slaver Node, on their backs which gives him control of their minds and boosts their fighting abilities. It is revealed that Ichigaki is the one who originally infected their master in order to manipulate them. He is voiced by Ryuuji Saikachi in the Japanese version and James Fields in the English dub
