Who Voiced Uncle Iroh: The Definitive Guide To The Voice Actors Of Avatar: The Last Airbender In 2026
Note: This article focuses specifically on the iconic character Uncle Iroh from the animated television series Avatar: The Last Airbender and its legacy, detailing the talented voice actors who brought him to life across various media through 2026.
The legacy of Avatar: The Last Airbender endures as one of the most culturally significant animated achievements of the 21st century. At the heart of its emotional resonance is Uncle Iroh, the wise, tea-loving former Fire Nation general who serves as a surrogate father figure to Prince Zuko. Understanding who voiced Uncle Iroh requires examining the tragic loss of his original voice actor, the seamless transition to a legendary successor, and the broader vocal landscape that has sustained the character across video games, spin-offs, and multimedia projects in 2026.
The Original Voice of Season 1 and 2: Mako Iwamatsu
The foundation of Uncle Iroh's distinct persona was established by the legendary Japanese-American actor Mako Iwamatsu, professionally known simply as Mako. Born in Kobe, Japan, in 1933, Mako brought a lifetime of theatrical, film, and television experience to the recording booth. His career included an Academy Award nomination for The Sand Pebbles and numerous foundational roles in Asian-American theater.
When Nickelodeon cast Mako in 2005, his deep, resonant vocal timbre and gentle cadence immediately defined Iroh's duality as a terrifying combatant and a benevolent, tea-sipping mentor. Mako voiced Uncle Iroh throughout the entirety of Season 1 and Season 2, as well as the first few episodes of Season 3.
Unfortunately, Mako passed away from esophageal cancer on July 21, 2006, during the production of the final season. His final vocal performance for the series is immortalized in the poignant Season 2 finale, "The Crossroads of Destiny," and the early Season 3 episodes where Iroh languishes in a Fire Nation prison.
The Succession and Legacy of Greg Baldwin
Following Mako's passing, the production team faced the immense challenge of finding a replacement who could honor Mako's legacy without disrupting the audience's immersion. Greg Baldwin, an accomplished voice and stage actor who had worked alongside Mako in theatrical productions and had served as Mako's understudy and sound-alike on prior projects, stepped into the role.
Baldwin debuted as Uncle Iroh in the latter half of Season 3, notably voicing the character during the emotional redemption arc in the series finale, "Sozin's Comet." The transition was so seamless that many casual viewers did not realize a recast had occurred.
In the years following the original series wrap, Greg Baldwin has become the official custodian of the character. He has reprised the role across numerous official properties, including:
- The Legend of Korra (appearing in spiritual flashbacks in seasons 1 and 3)
- Video game adaptations such as Avatar: The Last Airbender – Into the Inferno
- Fan-favorite web series, charity streams, and promotional content for the franchise

The Vocal Style and Philosophy Behind Uncle Iroh
Voicing Uncle Iroh requires a unique combination of theatrical gravity and lighthearted warmth. Both Mako and Greg Baldwin mastered the specific vocal delivery needed to portray a man carrying profound personal grief—having lost his son, Lu Ten, at the Siege of Ba Sing Se—while maintaining an optimistic, patient demeanor toward his troubled nephew.
Key elements of the vocal performance include:
- The Gentle Cadence: Slow, measured phrasing that conveys wisdom and prevents the character from sounding rushed or panicked, even in high-stakes combat situations.
- Warm Humor: A hearty, rumbling chuckle that underscores Iroh's appreciation for simple pleasures, such as jasmine tea and playing Pai Sho.
- Commanding Authority: A sudden, terrifying drop into a deep, gravelly register when Iroh is forced to utilize his formidable Firebending mastery, reminding viewers of his past as the Dragon of the West.
Behind-the-Scenes Production Realities and Voice Direction
Recording voiceover for an animated epic like Avatar: The Last Airbender involves meticulous voice direction. Voice directors Andrea Romano and later dialogues teams worked closely with Mako and Baldwin to ensure the emotional weight of Iroh's philosophical advice hit home for a younger demographic while remaining profound for adult viewers.
When Baldwin took over the role, he studied Mako's specific vowel placements and breathing patterns. This technical dedication ensured that the emotional scenes—such as Iroh singing "Leaves from the Vine" (Little Soldier Boy) in the "Tales of Ba Sing Se" episode—retained their heartbreaking impact, even though Baldwin recorded subsequent musical cues and dialogue lines years later.
