One of the reasons I love Avatar: The Last Airbender is the symbolism inside the show.
In the final battle, Ozai (archvillain) to show his power, creates 3 fire blasts.
Ozai, with fire being his only available element, can create 3 blasts, and avatar shows how superior he is by creating 5 blasts, essentially beating Ozai in his own league. Without even going to the other elements (earth, wind, water).
The display of superiority invites Ozai towards the peaceful resolution (him giving up), but only after he refuses to surrender the fight continues - reinstating the peaceful intentions of the avatar.
