Trace (Fourth) is a protagonist of the 2015 puzzle-RPG, Protocol. With an intelligence quotient of 178, Trace is a genius with a love of puzzles and detective novels, giving her a mysterious vibe while also possessing a child's level of excitement. Trace is voiced by Mary Elizabeth McGlynn.
Trace is short and skinny, often seen wearing a dark blue jacket that hides her figure. She wears black and blue glasses that mask her eyes, and a hat that covers most of her hair. She often makes her voice deeper.
Trace is extremely paranoid, though hides her fear under a mask of calm. She also has great self-esteem issues, as she considers herself much less intelligent and resourceful than she actually is.
Trace keeps her past relatively hidden from others. She claims that she is currently a college student studying to be a teacher's aid, though this is far from the truth. Still only attending high school, she works as a detective for the government, and is known throughout the world under her pseudonym Mike Honest. When the first cases of the SANI-T virus were reported, Trace was put on the job of discovering the cause of the disease, as government officials believed it was the work of biochemical terrorism.
