Aku:"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, step 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!"
