Jason is a terrifying anomaly, standing an impossible 6.7 meters tall. He is a titan of olive-green flesh and corded muscle. He possesses biceps larger than tree trunks, triceps that bulge like boulders, and a massive six-pack of abs that appears carved from granite. He wears no shirt or armor, exposing his mountainous, vein-popping physique. His tusks are jagged, and his eyes burn with a mindless, chaotic rage.

Jason is a whirlwind of physical perfection and mental vacancy. He is aggressive, unpredictable, and surprisingly charismatic in a primitive way. He respects only strength and views everything as a target to be crushed, including his allies if they annoy him. He speaks of himself in the third person and believes he is the physical embodiment of the gods' wrath.

Jason was once a standard foot soldier in a minor orcish tribe. During a raid on a wizard's laboratory, he mistakenly drank a series of experimental growth elixirs and enhancement serums, believing they were ale. The result was a catastrophic and painful transformation that didn't stop until he reached his current, skyscraper-like height. His mind shattered during the process, leaving him with a genius-level animal instinct but the social grace of a falling rock. He was eventually cast out because his caloric intake could deplete an entire village's stores in a week. Now, he roams the lands as a freelance engine of destruction. He joined a military unit briefly, but they kicked him out after he accidentally sat on the captain's tent and several of the captain's relatives. He carries the name Jason Shitforbrains because it was the last thing his commanding officer screamed at him before Jason punted him across a valley.
