This towering behemoth is as ugly on the inside as he is on the outside. After years of experimenting with ways to bring people pain, even accidentally inflicting wounds on himself by means of corrosive acid splashed on his scalp and some of his now unfunctional left eye, he finds his only joy in murder, and the gorier and more sickening the better. Also a known rapist and criminal, evading a LOCK bounty, Mort has bigger things on his mind. In constant search of Wayne, he is always looking to beat Rex to the punch. If not for Rex's ego allowing him to boast whenever he finds out information before Mort, he most likely would have killed him in a rewardingly slow, agonizing way. However, he would rather continue to benefit from his adverse informant, hoping his practice at stalking down victims over Rex's die-hard mannerisms will reward him in the end - slow and steady wins the race, as it were. It's unknown what Mort did before becoming a roaming madman, or what drove him to this point, but despite his disgusting existence, he doesn't seem to mind too much about himself... or is that just how it seems?
