Tom had a short crop of smooth light hair in an undercut. He was average height and wore the traditional trainee uniform.
During the invasion of Trost in the year 850, he is part of the squad including Jean and Mikasa whose maneuvering equipments start to run out of propulsion fuel. He and the rest of the soldiers are rallied by Mikasa's inspirational speech to retake the Headquarters.
However, he runs out of gas on the way and he is surrounded by a group of Titans. Two of his team mates rush in to help him against Jean's orders, and are both killed as a direct result. Tom's head is then bitten off by a Titan and he is devoured. Jean, who is in charge of the squad, capitalizes on this opportunity and uses him as bait to distract the Titans while the rest of the squad make their way back to the Headquarters to resupply.
