Met his match, eh? That's too bad. I would have liked to of pounded him into the ground myself. Any fighter that relies on frogs to win can't be that good. [He laughs, what a ridiculous technique.] But yes, I understand the horror of having to live through a shift. If I have to experience another again it'll be too soon.

[He thinks for a second to try to explain Ki.] You see Tenten, it's very much a life energy, encompassing the entire body and once you run out you are left to your own life force alone, but Ki can be restored of course. It is a renewable resource. It's also similar to chakra in the fact that everyone can use it, but it takes much training to be able to harness it. It's not something you can manipulate elements to, or conjure strange creatures, it's an incredible destructive force that not only manifests in energy blasts but enhances the user's speed and strength. Some races have an easier time with it than others. Like this.

[He holds his own hand up, opening it so it sat flat with the bottom of the camera- until a ball of energy formed in the palm of his hand, somewhat large and glowing quite brightly. But it fades as he dismisses it.] That show was only a billionth of the destructive force Ki can have.
