Gelgar

Gelgar (ゲルガー) was a member of the Survey Corps until his death.

Story
Gelgar is one of several soldiers (the others being Henning, Lynne, and Nanaba) brought by Mike Zacharius to oversee a group potentially untrustworthy Survey Corps members. The group was assembled close outside of Wall Shina, and disarmed of their weapons due to the suspicion that one of their number might be an accomplice to Annie Leonhart.

Before an investigation can begin, Titans appear within Wall Rose. Mike orders the group to split into four squads to warn the nearby villages; Gelgar is placed in charge of the South squad. He leads his team to investigate Wall Rose for breaches, but rejoins with another group coming from the opposite direction without finding any. As night falls, the two groups take refuge in Castle Utgard.

Castle Utgard soon comes under attack from numerous Titans capable of moving during the night. Since the soldiers who'd been under suspicion don't have Three Dimensional Maneuver Gear, Gelgar and Nanaba take the lead in engaging the Titans. However, Gelgar quickly runs out of swords and, after sustaining a head injury, the strength to continue fighting. He falls off the wall and is thrown into Castle Utgard by a Titan. Spotting a bottle of Vine on the floor, Gelgar is happy that he'll at least have a final drink before dying; however, the bottle turns out to be empty, and Gelgar spends his final moments demanding to know who drank it. A Titan then reaches through the window and kills him.
