Lobov was a man of average stature and a heavier build. He had hazel eyes and short dark brown kept longer at the front and parted to the side. While in the Garrison he could be seen wearing the standard Garrison uniform.
He appeared to have a high-strung and rigid personality, with a huge respect for the duties of a soldier. Upon over-hearing a soldier's talks of fleeing the battlefield, Lobov was so appalled that he threatened to execute the soldier on the spot.
During his time in the Scout Regiment, Lobov showed a degree of bravery by electing to protect the airship in its retreat. His insistence that he was just a recruit, despite his former position, and his rejection of the Garrison and its members, imply Lobov saw himself as a new man after changing divisions.
While awaiting orders during the battle of Trost, Lobov overhears a trainee soldier threatening to flee, and confronts him. When the boy reiterates his intentions to leave, Lobov draws his swords, threatening to execute him if he leaves. Their confrontation is interrupted by commander Dot Pyxis, who announces the Garrison's plan to reseal Wall Rose.
After the secrets of Eren Jaeger's basement are made public, Lobov transfers from the Garrison to the Scout Regiment, feeling that the revelations of the outside world have made its existence redundant.
Lobov is among the soldiers that take part in the attack on Liberio. As the Scouts make their retreat via airship, Lobov elects to wait outside of the ship and make sure that all of the Corps' soldiers return. As he is patrolling, he catches sight of a civilian following the airship on the ground. He is caught off guard to when he realizes it's a little girl, giving her enough time to shoot him in the eye, killing him.
