Harutara

Harutara is a Het ship between Haru and Katara in the Avatar: The Last Airbender series.

Canon
Katara first saw Haru when he was practicing his earthbending in the woods. He ran away as soon as Katara approached him so she followed him back to his village. She told him that she saw him earthbending in front of his mother and learned that he would be arrested if he was caught and that this happened to his father. Katara later talked with Haru and sympathized with him because she lost her mother to the Fire Nation. Haru explained to Katara that he likes to earthbend because it reminds him of his father.

Katara and Haru later encountered a man trapped in a mine so Katara encouraged him to earthbend and save him. Unfortunately, Haru was arrested overnight. Katara was upset when she found out and was determined to save him. She purposely got herself arrested so that she could go find Haru. They were reunited on a prison rig and Haru introduced Katara to his father Tyro. Katara had trouble getting the earthbenders to rebel against the Fire Nation but Haru eventually stood up along with her. After the earthbenders won, Haru thanked Katara and invited her to reclaim his village with him, but Katara had to go to the North Pole with Aang.

Several months later, Haru joined the forces in the Fire Nation invasion. He and Katara were reunited at the black cliffs where the forced met before heading to the capital. They hugged and Katara told Haru that she was really happy to see him. They participated in the invasion but it failed so they escaped on Appa along with the other children and teenagers. They both sought refuge in the Western Air Temple but were forced to separate when Azula attacked. Haru and Katara were both later at Zuko's coronation as Fire Lord.

Fanon
Harutara has a small amount of popularity in the Avatar fandom. It is not nearly as popular as Kataang, Zutara or even Jetara. Still, it has a small amount of fans and is considered to be one of the four main Katara ships. A lot fans speculated that there was a possible romance between the two or that at least Haru had a crush on Katara. However, Katara ended up with Aang at the end of the series. Still, some fans love Harutara and insist that it could have worked. Harutara does not have a large amount of fanon but some fan works are still out there.
