That's right, Aku! You see, I'm smart, and you are pure evil...and I knew you would cheat. So I had a fake sword made and hid it under that rock over there. Then I hid the real sword right down... [notices the sword is gone, then looks up to find another minion holding it] here.
I see…you. I see…inside…of you. A gentle soul. A…compassionate heart. A warrior's spirit. In selfless service. It is in your nature to sacrifice all…for what is right. Forever giving, you…are a hero.
Seems like Aku got himself a little problem... a problem that won't go away... a samurai problem. I wanted nothing to do with it but that funny scientist informed Aku of my emotions. They got Lulu... sweet thing. I have no choice. Damn feelings. I came out of retirement.
Your father, the Emperor, shortly after you were born, gathered together the chiefs of all the great tribes of the world. We devised a plan. A plan that would prepare you for the ultimate battle against the ultimate evil. Aku must be destroyed and only you can wield your father's magic sword. Together you are the one instrument that can stop this evil.
