In the year 854, Reiner's appearance does not change much, except for the fact that he has grown slightly in height, has lost corpulence, and also has a slight goatee-shaped beard. During the battle at Fort Slava, he wore the standard uniform of the Marleyan army soldiers and in planning the upcoming invasion on Paradis Island, he wore a long coat with a shirt and a tie. Like all of his Eldian compatriots in Marley, Reiner wears the arm bracelet that identifies him as someone of this race.

When he was a child, Reiner used to be someone who was calm but at the same time very impulsive, he joined the warrior program in the hope that his Marleyan father could live with him and his mother, even after being rejected by his father. He was extremely known among his peers for his loyalty to his superiors, this being the only quality that made him stand out as a recruit, his self-confidence grew greater after having acquired the power of the Armored Titan but this immediately collapsed when Marcel He revealed to him that he had not been chosen for his abilities. Reiner's mentality was shaped by the words of his mother and his superiors, who incessantly told him that the inhabitants of Paradis Island were a horde of demons that threatened to destroy the world.

After Marcel's death, Reiner adopts part of his personality by becoming more assertive, being willing to blackmail both Annie and Bertolt to ensure that they follow his orders, thus taking leadership of the group. Upon joining the 104th Cycle Recruit Troop, Reiner became completely equal to Marcel in terms of character, becoming a passionate, caring young man with a strong sense of duty. He took his role as a soldier so seriously that Bertolt constantly clarified to him that he was a "warrior" and not a soldier. He tends to always think of others before himself, assuming the consequences of his actions for the good of his colleagues.
