Amiba is a minor villain from Hokuto no Ken. He is an impostor of Toki who took on his name after the latter was imprisoned by Raoh's forces. He then used Toki's fame as a doctor to extort wastelander to "cure" their illness with his botched imitation of Toki's Hokuto Uchou Ken technique.
He has gained recurring memetic popularity in Japan due to a series of reader's fanfics on the magazine Fanroad that involves him appeared in various other anime he is completely unrelated to.
