Troy Baker voices Dr. Nathaniel Essex in Marvel's Wolverine — the character who becomes Mister Sinister. Essex starts the game as the leader of Team X and turns after being abducted by Bolivar Trask, which makes him the pivot of the story's antagonist structure. Gizmodo confirmed the role on August 13, 2026, after years of players identifying Baker's voice in trailers.
Who Nathaniel Essex is here
Essex opens the game as Team X's leader — one of Logan's own, not a villain waiting in the wings. The turn comes after he is abducted by Bolivar Trask, voiced by Jason Spisak.
In the comics, Nathaniel Essex is the civilian name of Mister Sinister, the Victorian geneticist obsessed with mutant DNA. Casting the character as a trusted ally first and revealing the name later is the game's clearest structural borrowing from the comics, where the Essex reveal is traditionally a slow burn.

The casting everyone had already guessed
Gizmodo, confirming the role in August 2026, noted that Baker's involvement had been an open secret for years — players picked his voice out of earlier trailers long before any announcement.
Insomniac handled the disclosure unusually. Rather than a press event or a trailer reveal, the news went out through same-day interviews with Variety and Entertainment Weekly on August 13, 2026.
That timing is itself a hint about the story: studios rarely confirm a voice role two years after fans identified it unless the character's identity was the thing being protected.
Where you know him from
Baker is among the most prolific voice actors in games. The roles most people recognise:
- Joel Miller — The Last of Us and Part II
- Booker DeWitt — BioShock Infinite
- Higgs — Death Stranding and Death Stranding 2
- Sam Drake — Uncharted 4
- The Joker — Batman: Arkham Origins
He is also no stranger to Marvel: he has voiced multiple Marvel characters across games and animation, which is part of why his presence in an Insomniac Marvel title surprised nobody.
The rest of the cast
Baker is one of several recognisable names here. Liam McIntyre plays Logan, Krizia Bajos plays Jean Grey, Nicole Pacent plays Mystique, and Kelly Hu — Lady Deathstrike in the 2003 film X2 — returns to the franchise as Tyger Tiger.
