Matthew Mercer’s Dual Life as Voice Actor and Dungeon Master

Few careers in modern voice acting blur the line between performer and world-builder the way Matthew Mercer’s has. Starting out as a teenager recording background crowd noise for anime dubbing studios, he built his resume one character at a time across two decades – eventually landing roles in some of the most beloved franchises in gaming and animation. The path from walla recordings at Animaze to Chief Creative Officer of a multimedia entertainment company is, in any measurable sense, an extraordinary one.

Born Matthew Christopher Miller in Palm Beach Gardens, Florida, Mercer grew up in a creative household – his father a musician and audio engineer, his mother an actress and writer. When the family relocated to Los Angeles, the entertainment industry was already on his doorstep. A childhood speech impediment, worked through with a therapist, may have sharpened his sensitivity to voice as an instrument. By high school, he was already picking up small roles in anime dubs, learning the craft from the ground up rather than from a classroom.

Leon S. Kennedy and the Resident Evil Legacy

When Mercer stepped into the role of Leon S. Kennedy for Resident Evil 6 in 2012, he inherited one of gaming’s most iconic protagonists – a character introduced in 1998 and beloved by millions. His grounded, soldier-worn delivery gave Leon a believability that held up across subsequent entries, animated films, and spin-offs. The performance became a calling card for what Mercer does best: bringing weight and humanity to men under impossible pressure. Leon remains one of the longest-running and most consistent associations in his career.

Attack on Titan and the Making of Captain Levi

Captain Levi Ackerman in the English dub of Attack on Titan arrived at the right moment in Mercer’s career. The series became a global phenomenon, and Levi – quietly lethal, deeply principled, carrying grief he rarely expresses directly – demanded a voice that could convey restraint as intensity. Mercer delivered that across multiple seasons spanning 2013 to 2023. His take on Levi became a benchmark for English anime dubbing, frequently cited in conversations about performances that rival or complement their original Japanese counterparts.

Critical Role and the Reinvention of a Career

What began in 2015 as a live-streamed Dungeons and Dragons game among friends on Geek and Sundry became a cultural force that redefined what tabletop gaming could look like for a public audience. Mercer, as Dungeon Master, was at its center – crafting entire worlds in real time, voicing hundreds of non-player characters, and guiding stories that unfolded over hundreds of hours of content. The Mercer Effect, a term that entered gaming circles to describe how his style raised expectations for D&D storytelling, is a testament to how deeply the show penetrated its audience. Critical Role Productions grew from that streaming show into an independent media company. A campaign setting book, The Legend of Vox Machina animated series on Amazon Prime Video, and merchandise lines followed. Mercer’s title within the company – Chief Creative Officer – reflects a role that goes well beyond performing.

Overwatch, Fire Emblem, and the Video Game Catalog

The breadth of Mercer’s gaming work is striking. Cole Cassidy – initially released as Jesse McCree – in Overwatch brought him a gunslinger with a classic Western cadence, a character that earned him Voice Actor of the Year at the 2017 Behind the Voice Actors Awards. Chrom in Fire Emblem: Awakening gave him a place in Nintendo’s sprawling strategy franchise, a role that carried into Super Smash Bros. and Fire Emblem Heroes. Jack Cooper in Titanfall 2 anchored one of the most acclaimed first-person shooter campaigns of the decade. Yusuke Kitagawa in Persona 5 slotted into an already dense ensemble and held its own. Ganondorf in The Legend of Zelda: Tears of the Kingdom extended his reach into one of gaming’s most enduring villain roles. Each of these roles sits in a different genre, a different tone, and a different vocal register – reflecting the range Mercer has developed across more than two decades of sustained work.

JoJo’s Bizarre Adventure and Anime Dubbing at Its Peak

Jotaro Kujo in JoJo’s Bizarre Adventure: Stardust Crusaders placed Mercer at the center of one of anime’s most stylized and beloved series. Jotaro is a character defined by cool economy of speech and sudden explosive authority – qualities that mapped well onto Mercer’s strengths. The performance extended through subsequent JoJo entries, cementing his place in a franchise that draws deeply dedicated fan communities. Trafalgar Law in One Piece, Kiritsugu Emiya in Fate/Zero, and Levi in Attack on Titan round out an anime resume that spans shonen action, psychological thriller, and military drama.
