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 forward 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! Gotta get back, back to the past Samurai Jack! (Watch out!)
