Dimitri is a tall 22-year-old man with chin-length, unruly blond hair with bangs falling over his eyes. He wears an eyepatch over his right eye, which he lost a few years ago. His other eye is blue. He wears full, black armor with blue accents, with a heavy blue cape lined with white and black fur. With a minor crest of Blaiddyd, he's very proficient with spears and lances.

Once levelheaded and composed, Dimitri is now rough, impulsive, violent, brooding, ruthless, and single-minded.
