Dimo Reeves was a merchant who led the Reeves Company, a merchant group named after him. He was based in Trost District for most of his dealings and had brief alliances with the Military Police Brigade and the Survey Corps, mostly outside of Trost.
Dimo Reeves was a short, overweight man. His head was balding with black hair on the sides and a thin dark mustache and beard. He had brown eyes and bright skin. He was usually well dressed, with a brown leather jacket, gray vest, and pink button-up shirt with red-brown dress pants and brown dress shoes.
During the Battle of Trost District, Dimo Reeves was a selfish businessman blocking the inner gate with his cart. He commented that people's lives were not worth half as much as his cart, and ordered them to push. He only relented when his life was threatened by Mikasa Ackerman, not due to any change of heart.
