Haru

History
Haru is a young Earthbender, whose Earth Kingdom village was occupied by the Fire Nation. Seizing the village's coal mines to fuel their ships, they extracted exorbitant taxes from the citizenry, and most cruelly, took all known Earthbenders to a prison shipyard, Haru's father Tyro among them. To ensure his safety, Haru's mother forbade him from earthbending (although he continued to earthbend in secret).

One day, as he was practicing alone, Aang and his friends stumbled upon Haru. While Haru and Katara struck up a kinship over shared parental losses, they came upon a villager trapped under a rock slide. Haru aided him through Earthbending, but the old man reported him even though his life was saved, and he was taken into custody.

Aang and Sokka then helped engineer Katara's false arrest for Earthbending, so she would be taken to the shipyard. There they and Haru helped stir up a mass prison rebellion and escape. Reunited with his father, and reinforced by fellow Earthbenders, Haru now has a chance of driving the Fire Nation from his home.

In The Day of Black Sun, Part 1: The Invasion, Haru is one of many familiar, but slightly changed faces recruited by Sokka to help in the war. He is seen coming of a boat with his father. Haru now has a mustache and small beard. He is there for the fight. When the submarines were destroyed, the warriors decided to surrender. The young people (Aang, Katara, Sokka, Toph, Teo, The Duke, and Haru) were put on Appa and sent away. Haru is temporarily part of Aang's group. They then headed for the Western Air Temple.

Haru has befriended both Teo and The Duke since the invasion, and upon arrival at the Western Air Temple, he and his two friends began to explore the Temple. They found it to be the perfect place to hang out and practice some earthbending.

Haru is currently still with Aang's group as of The Firebending Masters. It looks like Haru may be sticking with the group until the next invasion.
