Trilla has medium-length black hair in a bob, dark eyes, and sun-kissed skin. She is ruthless and devoted to the Empire, hunting down the enemies of the Empire, the Jedi. She is skilled and trained in the use of the Force and lightsabers, as well as hand-to-hand combat. She is also one of the few Inquisitors who does use blasters, unlike the others' disdain for them, showing that she prefers to carry out her mission by any means necessary. She is paranoid, cold and sadistic.
