Vachir

Vachir was a member of the Rough Rhinos, a Fire Nation group, and served as the team's bowman. The tattoos on Vachir's face and his skill with a bow suggests that he was at one point a member of the Yu Yan Archers. He specialized in fire arrows and his bow had a small torch just below the grip to ignite them. Vachir, along with the rest of the Rough Rhinos was responsible for the deaths of Jet's parents and the destruction of their village.

History
In Spring, 100 ASC, the Rough Rhinos attempted to capture the Earth Kingdom's Chin Village in honor of Fire Lord Ozai. During this fight, Sokka reflected the sun in his magnifying glass to distract Vachir. Vachir turned and fired at the source of the light without being able to take aim properly. His arrows missed Sokka; instead they embedded themselves into Yeh-Lu's saddle bag which contained four sticks of dynamite. Yeh-Lu picked up the bag and threw it on the roof of a neighboring house where it exploded, burying Yeh-Lu under debris. While Vachir was still distracted, Katara sneaked up behind him and used her water whip to cut the saddle straps. Vachir fell off and was dragged by his fleeing rhino.

Later that Spring, the Rough Rhinos ran into Iroh and Zuko. Vachir shot a lit arrow at Zuko's back. Zuko sensed the arrow, turned, and broke the arrow apart as it approached him. Zuko then let a fire blast loose, which burned a hole in the archer's bow, a hand's width above the archer's hand. The blast passed through the bow and broke the string leaving Vachir weaponless.

The ultimate fate of him and the Rough Rhinos after the War is unknown
