Juno

Juno was an orphan under the care of Grandma Lokai. He built a hut not far from Grandma Lokai's Earth Orphanage, and has since become a thief, along with three other orphans. He is shown to be quite tempermental.

History
While lounging in his hut with his friends, Juno encountered Katara and Sokka, who had been separated from the rest of Team Avatar after a storm. He was outraged when Sokka landed on his hut, destroying it. He and his fellow thieves proceeded to interrogate the duo, using Sokka's weapons to threaten them. Katara used Waterbending as a diversion, and told her brother to start running. Katara and Sokka reached the river, much to Juno and his friends' disappointment. She then raised a giant wave of water, and Sokka forced the thieves to return his belongings. They did so reluctantly, and Katara brought down the wave, pushing Juno and his friends back.
