Kahchi

History
Kahchi is a member of the Fire Nation group called the Rough Rhinos. Kahchi's weapon of choice is a halberd. He, along with the rest of the Rough Rhinos, is responsible for destroying Jets home village, along with the death of his parents.

In the episode "Avatar Day," the Rough Rhinos attempt to capture the Earth Kingdom town of Chin for the Fire Lord. To scare the village, Kahchi uses his weapon to destroy the statue of te village's founder. When Aang approches Kahchir, he readies his halberd. Aang leans forward and extends his arms out behind him, each hand holding one of Kyoshi's fans, which he opens as he runs. He spins aside out of the rhino's way at the last moment and uses the fan to Airbend Kahchi out of his seat and off the side of the cliff.

In the episode "The Desert", the Rough Rhinos run into Iroh and Zuko. Ogodei swings his ball and chain at Iroh. Iroh kicks the ball away. The ball, redirected, wraps its chain around the foot of Kahchi's rhino. Iroh rises back up and swats the rump of the rhino that had been chained. The rhino runs off, yanking Ogodei and Kahchi away. Iroh then waves as he watches them go. It is unknown what happens to the Rough Rhinos and Kahchi next.
