Tom is one of the graduates from the 104th Training Corps.
During the invasion of Trost in the year 850, he is part of the squad including Jean and Mikasa whose Maneuvering Gears start to run out of propulsion fuel. As his fuel finally depletes, he becomes surrounded by a group of Titans and is killed. Jean, who is in charge of the squad, capitalizes on the opportunity and uses him as bait to distract the Titans while the rest of the squad makes their way back to the Headquarters to resupply.
