John Gremillion

Gremillion voices Calvi in the English dub of Attack on Titan, the general in command of Marley's military and the highest-ranking Marleyan official to appear in the series. Calvi holds deep pride in Marley's history and places great trust in Zeke Yeager's loyalty to the nation, a trust that proves fatally misplaced once Zeke's true plans against Marley come to light. The character meets his end during the Tybur family's festival when the Attack Titan bursts into the ceremony and turns on Marley's assembled military leadership. It is a smaller but consequential role in the story's Marley arc.

Gremillion holds a film degree from the University of Texas at Austin and trained in drama at the Juilliard School, building a career from there centered on English-language anime dubbing. His credits include Dracule Mihawk in One Piece, Gentle Criminal in My Hero Academia, and Roland Chappelle in Food Wars, along with Arthur Randall in Black Butler and Hakuoro in Utawarerumono. He has also voiced Yamato Hotsuin in Devil Survivor 2: The Animation, Nobuteru Irihata in Haikyu!!, and Takeshi Hirokawa in Parasyte, rounding out a resume built largely on supporting and antagonist roles.
