Amnesia occurs quite a lot in Bionicle. How do you feel about it? And do you think it helps the story?
Take Takua for example: He's an Av-Matoran and losses his memory to go undercover as a Ta-Matoran. Then gets stuffed in a Matoran Sphere and losses his memory again. Then he crash lands in the sand and losses his memory AGAIN. I swear there's some Great Being out there who just enjoys making Takua lose his memory.
