Gralik took great pride in his work, often insisting on checking and rechecking that the kemocite was pure enough for whoever had ordered it. He refused to let his work be corrupted, however, by selling kemocite to weapons manufacturers.
Gralik was fond on taking long walks in the wilderness outside the colony; he sometimes hunted tree scarabs.
In October of 2153, Gralik was informed by Captain Jonathan Archer that his facility was providing kemocite for the manufacture of a superweapon. Disgusted that his materials had been used to kill seven million people, Gralik sabotaged the final kemocite shipment to Degra, making it very impure. (ENT: "The Shipment")
