Amiba

Amiba (アミバ) is a character in Fist of the North Star: Ken's Rage. He once trained with Rei but failed to meet the standards of the school and fled. Considering himself a genius in spite of his failure, he hears of the Village of Miracles and sees the seemingly magical healing performed by Toki. Thinking that he could do the same, he tries to mimic Toki's technique and tries to heal an old man, unintentionally causing him agony. The old man's screaming causes Toki to lightly punch Amiba in the face whilst he hurries to undo the damage. When Amiba tries to oppose him, Toki warns him to not face him and the differences between their prowess is clear. The incident wounded Amiba's pride and he hated the healer for it. He eventually resorted to crime and became a subordinate under Raoh, telling him Toki's whereabouts.

Although Raoh didn't order him to do so, Amiba makes himself as close as he could in Toki's appearance in order to ruin the latter's reputation. He kills the innocents who aren't willing to follow him in the Village of Miracles and starts experimenting on the remaining resistance, calling them "dummies". He experiments on any survivors to try in vain to perfect the Hokuto Shinken style. A few of his "test subjects" lose their human minds and transform into ruthless beasts. When Kenshiro begins his search for Toki, he accidentally mistakes Amiba for his brother until Rei tells Kenshiro his foe's real identity. Amiba believes that he can kill Kenshiro and make himself the "real" Toki, but he is easily defeated. Kenshiro presses a pressure point in his legs, making him unable to control them as they gradually walk him off a tall skyscraper. He plummets to his undignified death and cries one of his famous lines with fans, "Uwaraba!"

Fighting Style
After numerous horrific pressure point "experiments", Amiba has devised a self-taught fighting style based on Hokuto Shinken. One source says that he actually learned the basics of Hokuto Shinken from Jagi shortly after leaving the Village of Miracles. Amiba has largely abandoned his previous training in Nanto Suichōken in favor of his self-taught style. He attempts to pass off his style as Hokuto Shinken to onlookers, but actually lacks the equal ability of those who have truly mastered the martial art. At one time, Amiba said that he will name his self-taught style Hokuda Shinken (北蛇鍼拳 "North Snake Needle Fist").
