In the 阿凡达 episode "Nightmares and Daydreams" (season 3), what are the 日本动漫 toons that Aang dreams he is?

It is from season 3 episode 9, right before the "Day of Black Sun". He dreams that he is facing the Firelord several times. I know that they are "loosely based" off other 日本动漫 toons (thank 你 阿凡达 Extras) but which ones? I think the first one is 悟空 from DragonBall, but what about the other two?
