Then here is a serious one ^^.
Motoko Kusanagi, from "Ghost in the shell".
She is a serious characher, being the protaganist in the anime and the two movies.
She is a cyborg in a world were noone can say the definition of a human being.
And most interesting of all: She questions wether she is real, or if her first memories are programmed beforehand.
Seriously, i reccomend the anime to anyone.
