Vachir

Vachir is a member of the Rough Rhinos, a Fire Nation group as the team's bowman. The tattoos on Vachir's face and his skill with a bow suggests that he is or was at one point a member of the Yu Yan Archers. He specializes in fire arrows and his bow has a small torch just below the grip to ignite them.

History
When he was a child, he attended the Fire Nation School and one of his teachers was Ms. Kwan.

In Summer, 100 ASC, the Rough Rhinos attempt to capture the Earth Kingdom town of Chin for the Fire Lord. During the fight, Sokka uses reflected sun from his magnifying glass to distract Vachir. Vachir turns and fires the arrows. These miss Sokka, instead hitting the saddle bag bag attached to Yeh-Lu's rhino who had just appeared behind Sokka. The saddle bag contains four sticks of dynamite. Yeh-Lu picks up the bag and throws it on the roof of a neighboring house. A moment later, the house disappears under the thunderous explosion, rendering Yeh-Lu incapable of any more fighting. While he's stilll distracted, Katara sneaks up behind him and uses her water whip to cut the saddle straps. Vachir falls off and is dragged by his fleeing rhino.

Later that Summer, the Rough Rhinos run into Iroh and Zuko. Vachir shoots a lit arrow at Zuko's back. Zuko senses the arrow, turns, and breaks the arrow apart as it approaches him. Zuko then lets a fire blast loose, which burns a hole in the archer's bow, a hand's width above the archer's hand. The blast passes through the bow and breaks the string leaving Vachir weaponless. It is unknown what happens to the Rough Rhinos and Vachir next.
