Dr. Ichigaki

Dr. イチガキ

Dr. Ichigaki is a demon scientist who took advantage of three martial art students by poisoning their master. Dr. Ichigaki then appeared and offered to heal their master if they agreed to participate in an experiment of his. Dr. Ichigaki turned them into Makai minions (Usually called M1, M2, M3, or Dr. Ichigaki's minions). After his team's defeat in the tournament, he unveils a serum ("Instant Gene Therapy") which almost instantly enhances him into a monster form, but is creamed by Yusuke just as quickly. In the manga he is confirmed to be alive.
