Lian tries to attach Aang to the machine, but he battles it instead.
During the fight, Katara is struck down, causing Aang to enter the Avatar State and destroys the machine, burying Lian under its rubble, killing her (though she survives in the portable versions of the game.) As the four leave the fortress, Zuko is seen crawling up on the shoreline, grumbling angrily.
They arrive at the Water Tribe as a Fire Nation ship attacks, led by Prince Zuko.
They are able to fend off the attackers, but Katara is captured during the battle.
The game was a launch title for the Wii in Western territories.
