The Last Airbender
The movie begins with Katara and Sokka finding an iceberg and freeing Aang, the last airbender, and his flying bison, Appa. This attracts the attention of Zuko. Arriving to the Southern Water Tribe, Zuko demands the elderly under the impression that Avatar is an old person until Aang is found. Aang surrenders himself to Zuko as long as he agrees to leave the village alone. Eventually he manages to maneuver away from the guards before Katara and Sokka arrive on Appa, making their escape. Aang and friends visit the Southern Air Temple where the Avatar learns that he was in the ice for 100 years and the Fire Nation killed all the airbenders. It was there Aang meets up with the only known remaining "flying lemur", naming it "Momo" as it joins Aang's group.
