When Gremmy Thoumeaux made his long-awaited animated debut in Bleach: Thousand-Year Blood War, fans immediately wondered who brought the chilling, reality-bending Sternritter V to life. Portraying a character whose imagination dictates physical reality requires a very specific vocal range—one that balances childish innocence with terrifying, god-like menace.
The dual-language voice cast for Gremmy delivered standout performances that defined one of the most memorable battles in Tite Kubo's final arc. Natsuki Hanae voices Gremmy in the original Japanese audio, while AJ Beckles handles the English dub role. Both performers capture the eerie duality of a young boy holding the power to rewrite existence itself.
Japanese Voice Actor: Natsuki Hanae
In the Japanese release, Natsuki Hanae steps into the role of the Sternritter known as "The Visionary". Hanae is widely recognized across the anime industry for voicing complex, emotionally intense characters, including Tanjiro Kamado in Demon Slayer: Kimetsu no Yaiba and Ken Kaneki in Tokyo Ghoul.
Casting Hanae for Gremmy was a deliberate choice by the sound production team. Gremmy appears physically as a young, unassuming boy with blonde hair and a blank expression, yet he possesses unmatched destructive capability. Hanae utilizes a soft-spoken, airy cadence that effortlessly shifts from innocent curiosity to chilling psychopathy. When Gremmy casually manifests meteors or alters bone structures, Hanae's delivery maintains an unsettling calm, selling the idea that Gremmy views reality like a sandbox game. Additional reporting by Bloomberg delves into related views on this issue.
- Major Career Roles: Tanjiro Kamado (Demon Slayer), Ken Kaneki (Tokyo Ghoul), and Kosei Arima (Your Lie in April).
- Vocal Style for Gremmy: Gentle, breathy, and deceptively youthful, shifting instantly into unhinged intensity during combat.
English Dub Voice Actor: AJ Beckles
For viewers watching the English dub of Bleach: Thousand-Year Blood War, AJ Beckles voices Gremmy Thoumeaux. Beckles has steadily built a prominent resume in modern shonen dubs, bringing dynamic energy to breakout characters.
Beckles adopts a crisp, youthful tone that matches Gremmy's youthful avatar while infusing the dialogue with an arrogant, detached superiority. Because Gremmy spends most of his screen time treating his fight against Kenpachi Zaraki as an effortless experiment, the English performance relies heavily on subtle inflections of boredom and superiority. Beckles manages to sound both detached from mortal concerns and completely fascinated by his own limitless imagination.
- Major Career Roles: Takemichi Hanagami (Tokyo Revengers), Hero (Fairy Tail), and Gabriel (The Case Study of Vanitas).
- Vocal Style for Gremmy: Arrogant, smooth, and chillingly casual when discussing mass destruction.
Character Profile: Who Is Gremmy Thoumeaux?
Understanding the voice performances requires looking at who Gremmy is within the Wandenreich ranks. Designated as Sternritter "V", standing for The Visionary, Gremmy is considered by Yhwach to be one of his most powerful subordinates. His Schrift allows him to turn anything he imagines into absolute reality. If he imagines his body is as hard as steel, it becomes unbreakable. If he imagines an opponent's bones turning to cookies, they instantly transform.
Despite this god-tier ability, Gremmy's psychology is his primary flaw. Having been isolated and treated as a living brain preserved in a glass jar before being given a physical body, he lacks true emotional maturity. His childlike frame reflects his true mental state: he is an imaginative child playing with apocalyptic tools without understanding the weight of mortality. This psychological immaturity makes the voice performances by Hanae and Beckles critical, as they have to sound simultaneously ancient in power and childish in temperament.
The Iconic Matchup: Gremmy Versus Kenpachi Zaraki
Gremmy's primary narrative purpose culminates in his brutal showdown against Captain Kenpachi Zaraki. This battle serves as a thematic clash between brute, earned strength and infinite, unchecked imagination.
Throughout the fight, Gremmy scales his imagination higher and higher, creating outer space vacuums, massive iron pillars, and eventually a giant meteorite. Both voice actors excel during this escalation sequence. As Gremmy begins to feel fear and excitement for the first time against Kenpachi, their vocal delivery breaks away from cold detachment into frantic, unstable panic. This emotional cracking is what transforms Gremmy from a standard overpowered villain into a tragic, terrifying entity consumed by his own limitless thoughts.
