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!
What is wrong, friend? Odds are 3 to 1 you should have fun.
I too desire to find my home. You see, in days long past, where rockets and robots were nowhere near creation, a young warrior forged into battle with Aku. At the point where victory was eminent, Aku tricked the warrior and flung him from his own time to a distant time in the future. To reclaim his homeland and undo the evil of Aku, the warrior has to find some sort of time passage home. Such a magic is difficult to find.
Oh, put that thing away, Samurai. We all know what's going to happen. You'll swing your sword, I'll fly away, and probably say something like, "I'll be back, Samurai!" And then I'll flutter off over the horizon and we won't see each for... about a week. And then we'll do the same thing again.
Your word play will not trick me, villain!
[he attacks Aku]
No Wait! I'll be back, Samurai - you'll see! Bwah-ha-ha-ha.
[flutters over the horizon]
[reappears in front of Samurai Jack] See what I mean?
