There is some debating about there even being a season 4 of Avatar. I hope there's going to be one. But, if your wondering about Season 3, new episodes will air in July.
The last episode of "Avatar" was called "Book 3 Chapter 21: Sozin's Comet Part 4: Avatar Aang". This was the 4th Part of the Avatar Season 3 Finale.
If you mean who is the last air bender then its Aang from Avatar The last Air bender or Avatar the legend of Aang
