Rock Lee - Konohagakure's Beautiful Green Beast
Without the background and crap:
Updated for more sprites:
Yondaime Hokage - The flames were hell, pun intended
Konohamaru Sarutobi - Naruto's number one fan holding a fake Rasengan (Shippuuden pallet)
Naruto Uzumaki - Doing the Kage Bunshin and Rasengan. Not a good edit, I saw a better one somewhere.
