|“||I turned Toki into a murderer, Hokuto Shinken into the devil's art!||„|
|~ Amiba revealing himself shedding his Toki disguise.|
Later he teamed up with Jagi, who helped make Amiba resemble Toki and even scarred his back with a club to recreate Toki's scar. Amiba then learned enough Hokuto Shin Ken techniques from Jagi to successfully impersonate Toki. With the real Toki imprisoned in Cassandra, Amiba tarnished his image and tortured both civilians and martial artists with his experiments.
He performed sadistic "new pressure point tests" on living humans and reported his findings to Raoh. He also claimed that he could learn any martial art under short periods. He develops a style imitating Hokuto Shinken, which he names Hokuda Shin Ken (北蛇鍼拳, 'Hokuda Shin Ken'"Needle Fist of the North Snake") in Ten no Haō. Kenshiro finally used Zankai Sekihoken, causing Amiba to involuntarily walk over the edge of a high-rise building.
- Amiba and Jagi are considered the most cruel characters in hokuto no ken
- It's not known if Amiba blown his own hands or Kenshiro did it...
- Amiba was actually supposed to be toki,but it was changed so the story could go farther
