Marco Bott
Marco Bott is a member of the 104th Trainees Squad, and graduated as the 7th ranked trainee in his class. He was assigned to fight the Titans after the breach of Wall Rose, and given command of his own squad.
After the Colossal Titan attacked Trost, Marco was assigned command of the 19th Trainee Squad and ordered to support the vanguard forces. He was eventually among the trainees stranded when the retreat order was given, without enough gas to scale the Wall and escape Trost. When Mikasa and Jean rally the others into charging headquarters, which had become surrounded by Titans, Marco is quick to join them. Inside the station, he became vital in Armin’s plan to reclaim the overun supply room and leads the main group. Armed with rifles, the recruits acted as bait and lure the seven Titans occupying the room into position. Marco managed to maintain order in the group, keeping everyone calm until they could fire and blind the attacking Titans.
He is later seen among the regrouped forces, attempting to keep order when people like Dazz give into their fear. Marco did his best to comfort them and keep morale high, even when they were ordered to return to Trost. He joined the other recruits up on the Wall, acting as bait to distract the Titans from the main operation involving Eren Yeager. Later, he was among the recruits that head into the city to battle the Titans. There, he helped to rescue Jean when his gear malfunctioned and would eventually join the others in battling the Titans while Eren sealed the hole in Wall Rose.

He dies during the battle for Trost. His death serves to illustrate the grim reality of life for the soldiers, as even the most talented can meet an ignoble end while facing the Titans.
