Aku

Aku is the primary antagonist of the popular cartoon series Samurai Jack and is depicted as a demonic creature of near-infinite power and malice whose only real aim in existence seems to be spreading evil, in fact his name means "evil" in Japanese so he is very likely a living embodiment of such a force. Long ago in a distant land, I, Aku, the shape-shifting Master of Darkness, unleashed an unspeakable evil! But a foolish Samurai warrior wielding a magic sword stepped forth to oppose me. Before the final blow was struck, I tore open a portal in time and flung him into the future, where my evil is law! Now the fool seeks to return to the past, and undo the future that is Aku!
