Rodrigo Miallaret is a Brazilian actor, singer, and dublador with a career spanning over three decades, primarily in musical theater, before gaining recognition for his voice work in film and animation. His body of work as a voice actor is extensive, though his credits in anime are specific and limited compared to his roles in live-action dubs and western animation.

Born in Belo Horizonte on April 10, 1965, Miallaret's artistic journey began in his home state before he moved to São Paulo in 2002 to pursue a career in musical theater. His first major professional breakthrough came when he was cast in the Brazilian production of Les Misérables, followed by a role in the first mounting of A Bela e a Fera (Beauty and the Beast). This established him as a prominent figure in the Brazilian theater scene, where he has since appeared in numerous productions including O Fantasma da Ópera (The Phantom of the Opera), We Will Rock You, Jekyll & Hyde – O Médico e o Monstro, and Sítio do Picapau Amarelo - O Musical.

In the realm of anime, Miallaret has contributed to the dubbing of several series. A notable role is Demyne Shaft in the mecha anime Back Arrow, which was dubbed into Portuguese for its release on the Funimation streaming platform in 2022. His other anime credits include providing additional voices for the series SK8 The Infinity and The Saint's Magic Power is Omnipotent, both from 2021. While these roles are part of his professional portfolio, they do not constitute the central focus of his dubbing career.

Miallaret's voice acting is most prominently featured in major live-action and computer-animated film dubs for Disney and other studios. He is widely recognized for voicing paternal and authoritative figures, including Maurice, the father of Belle, in the 2017 live-action adaptation of A Bela e a Fera. He subsequently voiced the Sultão in the 2019 live-action Aladdin. That same year, he took on the iconic villainous role of Scar in the Portuguese dub of the photorealistic O Rei Leão (The Lion King), a performance for which he also sang the character's song, Se Preparem. His work also includes voicing Smokey in Carros 3, the Coelho in Christopher Robin: Um Reencontro Inesquecível, Butch in Tom & Jerry: O Filme, and Andrés in the musical animation A Jornada de Vivo. On television, he has dubbed characters such as Yusuf Khan in Ms. Marvel and Luthen Rael in Andor, as well as the father in the popular children's series Bluey.

Recurring collaborations are evident in his filmography. Many of his high-profile dubbing projects for Disney, including A Bela e a Fera, O Rei Leão, and Aladdin, were produced by TV Group Digital in São Paulo. His work frequently places him alongside a consistent pool of other prominent Brazilian dubbing talents and directors.

Notable achievements in Miallaret's career include critical recognition for his stage work, such as an APCA Award nomination and multiple Prêmio Bibi Ferreira nominations, one of which was for his portrayal of Vovô Joe in the musical Charlie e a Fantástica Fábrica de Chocolate. In voice acting, his achievement lies in becoming the definitive Portuguese voice for key characters in a new generation of Disney live-action remakes, bringing familiarity and gravitas to roles like Scar and the Sultão for Brazilian audiences. He has also applied his performance expertise as a judge on the reality talent show Canta Comigo Teen.
