@NarayanK: Say, what can plasma do? I'm not very into physics so I only learned a very vague idea of where it is and what it's kinda like. Please teach me! :D

To sum it up, plasma is an essential source of matter. I think there were four kinds, and the one [s]Travis[/s] Ryuu uses is thermal plasma. Basically, the kind of plasma he uses is the same kind of energy within lightning bolts. Plasma is generated when enough heat is generated, and usually acts as the core to natural fires and etc.; fires and lightning are intensely powered up by these hot lil guys.

Ryuu's plasma energy was intentionally nerfed by himself due to how dangerous it could get. After all, it's as hot as the core of a large fire. I might add in (to his CS) how the thermal heat is not exactly the same temperature like it should be.
