Lockjaw is a hulking brute, even by trandoshan standards. His scales are a molted hunter green, like the deep jungle, and if you stare at them for too long they almost appear to shift in shade. The most defining characteristic of this beast would be that his entire lower jaw and some of his face is cybernetic. A result of him accidentally disfiguring himself with his massive vibrosaw in one of his frenzied attacks. Lockjaw almost died as a result of the accident, but he has come back even more vicious and hateful.

Lockjaw takes twisted pleasure in taking sentient life, the more gruesome the better in his eyes. He is constantly trying to close with his prey to eviscerate them with his massive lumber-grade vibrosaw. He will settle for burning opponents alive with his wrist mounted flame projector if he is not able to reach them.
