Yeh-Lu

Yeh-Lu is a member of the Fire Nation group called the Rough Rhinos. Yeh-Lu is a master of explosives, his favorite weapons. He, along with the rest of the Rough Rhinos, is responsible for destroying Jet's home village, which lead to the death of both his parents.

History
In Spring, 100 ASC, the Rough Rhinos attempted to capture the Earth Kingdom town of Chin for the Fire Lord. During the fight, Sokka used reflected sun from his magnifying glass to distract Vachir. Vachir turned and fired the arrows. These missed Sokka, instead hitting the saddle bag attached to Yeh-Lu's rhino. The saddle bag contained four sticks of dynamite. Sokka smiled and ducked while Yeh-Lu picked up the bag and threw it on the roof of a neighboring house. A moment later, the house disappeared under the thunderous explosion, then his helmet rolled by Sokka, still crouched on the ground.

Later that Spring, the Rough Rhinos ran into Iroh and Zuko. When the two fled on an Ostrich Horse, Yeh-Lu rode in pursuit, throwing a grenade at the fleeing mount. The grenade exploded ahead of the ostrich horse, but Iroh and Zuko emerged through the dust of the explosion. It is unknown what happened to the Rough Rhinos and Yeh-Lu next.
