Found you whils't browsing Newgrounds dude! Nice animation!
Impressive fire, water, and air animations! And a funny build up to that boomerang boy!
bro make a remake with ok boomer in the backround when sokka does his wierd thing
It's a funny idea, with fluent movements.
I think it might be a little bit better with voice acting, i.e. if you parodied the show's intro, because it looks close to it already. “Water. Earth. Fire. Air. BOOMERANG!”
