Ozai
Ozai is an extremely skilled and powerful firebender, able to hold his own at the height of his powers due to Sozin's Comet against Aang despite Aang's status as a full-fledged Avatar. He is one of the few who can generate lightning along with Azula and Iroh, though he is shown to be the only one to shoot lightning out of both hands. With his firebending ability he is able to propel himself in the air similar to a jet. When Sozin's Comet arrives his firebending ability increases even more. After confronting the Avatar, Ozai's powers are taken away by Aang's Energybending.
