ChairBender
Only the Chavatar. Master of all chelements could stop the chfire nation.
"Long ago, the four chnations lived together in harmony, but everything changed when the Chfire Nation attacked. Only the Chavatar, master of all four Chelements could stop them, but when the Chworld need him most, he vanished. 100 years passed and my brother and I found the new Chavatar, a Chairbender named Chaang. And while his Chairbending skills are great, he has a lot to learn before he's ready to save anyone. But I believe Chaang can save the world."
