Marco Bott (マルコ・ボット,Maruko Botto?) is a supporting character of the series. He was a member of the 104th Cadet Corps, and graduated. He was assigned to fight the Titans after the breach of Trost District.
Marco is an idealistic young man, valuing the good of the group above his own interests. The others respect him greatly, and consider him to be a natural leader suited to his dreams of joining the Military Police. He is shown to be an excellent judge of others, recognizing Jean's potential as a leader and encouraging him to believe in himself. He is also shown to have a talent for preserving order among the others, whether resolving arguments or keeping them calm during battle.
Marco was an earnest and charismatic member of the 104th Squad, well-respected by the others for his leadership. He appeared to be very good friends with Jean, often holding him back or talking him down when he lost his temper. In fact, he recognizes Jean's potential as a leader and actively encourages him to embrace it since as someone that is "weak", he is able to empathize with others and make sound decisions. Marco acts as one of the 104th squad leaders during the Battle of Trost, and leads the team sent in to act as bait.
He expressed a strong desire to join the Military Police, stating he considered it a great honor to serve the King. This puts him into stark contrast with others, who express the desire to join in order to gain access to the comforts and relative safety of the inner territories.
He was later found alive after the breach of Wall Rose. Jean and Marco had a strange conversation on his assention. His 3D Maneuvering Gear was later found taken by Annie.
