Standing at 189 cm, Dorian possesses a lean yet muscular build with tawny dark skin that contrasts sharply against his layered black hair tipped in vivid crimson.

Though emotionally guarded after past heartbreak, his loyalty runs deeper than the ocean itself once someone earns his trust. On land he's already much stronger than a normal human. Underwater? He's terrifying.
