While I'm a HUGE fan of "Zuko - The Last Airbender", I must tell you that Zuko isn't really a lightning bender. Instead, he learned to redirect the energy of other people's lightning strikes that's aimed at him thanks to Uncle Iroh. The technique he taught Zuko—freezing harmlessly in place and then safely catching lightning as it arced into his hand—makes possible a form of discharge without end. It's worth noting: although he can't generate lightning himself, he is still able to handle it when other people shoot him with their bolts. Consequently, even though this skill might not be quite as practical for everyday use as throwing rocks by sending blasts out from one's fingertips like some kind of electric flower child wannabe (as we discussed above), at least he can't be roasted alive.
