Miglen Mirtchev is a French actor of Bulgarian origin who works extensively in both live-action and voice dubbing. Born in Bulgaria, he trained at the National Academy for Theatre and Film Arts in Sofia and has resided in France since 1984. He is fluent in several languages, including Bulgarian, French, English, and Russian, which has allowed him to perform professionally across multiple markets.

While Mirtchev has a substantial career in film and television, his voice acting portfolio includes French dubbing work for numerous American and international productions. He is noted for his deep, baryton-tenor vocal tone which he can augment with a pronounced Eastern European accent. This particular vocal quality has made him a recurring choice for characters with Slavic origins or imposing physical presences. In a 2021 interview, he discussed how his background and accent helped him land roles such as Olek in the series Banshee and Olek Burov in The Americans. Among his notable dubbing credits are the character Rhino in The Amazing Spider-Man: Le Destin d'un Héros and the voice of Santa Claus in the French version of the animated film Rise of the Guardians (Les Cinq Légendes). He also contributed to the French dub of the series Iron Fist. His live-action television credits include appearances in internationally recognized series such as Daredevil, Designated Survivor, Stranger Things, and Citadel.

The provided search results confirm his presence as a voice actor but do not list the role of l'Arbitre in Knights of the Zodiac among his verified credits. His professional background also includes extensive theatre work and roles in feature films such as The Command (Kursk), The Translators (Les Traducteurs), and Deception (Tromperie).
