???: But I was getting started with you, Sparx. You're strong enough now to fulfil your purpose. So what are waiting for? Join me right now. Become the Blade of Power.
Sparx: No way. I can't. Skeleton King told us, the only way the Blade of Power can be forged is if you and me fight. And for that. I'm not gonna fight.
Gibson: He's right. We have Enough.
