Aku

Long ago in a distant land, I, Aku, the shapeshifting master of darkness, unleashed an unspeakable evil! But, a foolish samurai warrior wielding a magic sword stepped forth to opposed 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!
