Grax

Grax was the zany and aggressive leader of the Hellfire clan. He was one of the five Goblin Commanders.

Personality
Grax was short-tempered, aggressive, and somewhat manic in his demeanor. He was a frugral and combative goblin, never one to waste precious resources.

Appearance
Grax was a red goblin with a single tusk and a mohawk of spikes. He had similarly red, beady eyes and was dressed in the leather armor Hellfires usually wear. He was missing an eye, presumably, and replaced it with one of metal and glass. Possibly, it was a cybernetic eye, as Hellfires do have some grasps over technology.

Opposing Grommel
Grax was the first to oppose Grommel, accusing his brother of murdering their creator, Fraziel. The bad-blood truly begins when the Stonekrushers take a soul fountain away from his control, which leads to a siege on their lumber mills.

He was also clearing forests and collecting copious amounts of gunpowder to create weapons of considerable destruction. However, he fails at both of these tasks, as Grommel beats him back to the very edges of his forests and destroys the last loyals of his clan until Grax is alone.

Death
Hiding among lumber and powder, Grax doesn't go willingly or quietly. He tries to take both himself and Grommel out in a powerful explosion, but the other assumes spirit form just in time.
