Yes, each member of Team Avatar along with the Order of the White Lotus was assigned a different task to end the Hundred Year War.
- Aang intercepted Phoenix King Ozai in Wulong Forest in order to defeat him. He did so by removing Ozai's bending through energybending, a feat unlocked by the lion turtle that he encountered earlier.
- Katara and Zuko traveled to the Fire Nation Capital in order for Zuko to claim the throne, as well as defeat Azula in an Agni Kai. After Zuko was severely injured by Azula's lightning, Katara intervened and defeated Azula by using the drain water directly below the Royal Plaza to encase her in ice.
- Toph, Sokka, and Suki disabled the Fire Nation airship fleet in order to prevent further damage to the Earth Kingdom. They destroyed the entire fleet by using an airship much like a boomerang.
- Lastly, the Order of the White Lotus, including Master Pakku, Iroh, Jeong Jeong, and King Bumi, liberated Ba Sing Se from Fire Nation control.
