Tomas Wagner was from Trost District. A member of the 104th Trainees Squad, he first met Eren Jaeger while questioning him about the Colossal Titan. Later, he operated the training equipment for the Vertical maneuvering equipment during Eren's second attempt at his aptitude test. At Keith Shadis' orders, Tomas exchanged equipment with Eren and it was discovered that Eren's equipment was defective. After graduating, Tomas planned to join the Scouting Legion.After the second attack of the Colossal Titan, he was assigned to the middle guard along with Eren Jaeger and Armin Arlelt. Initially tasked with working under the training corps, they eventually were incorporated into the front guard due to the number of titans. Catching the group unaware, a titan lunged at the rooftop they were standing on. The group scattered but unfortunately, Tomas wasn't fast enough. He was caught and swallowed whole, while his teammate, Eren, looked on in terror.
Eren would later avenge Tomas's death by brutally killing the titan responsible in his titan form.
