Dismuke began acting as a young child. His cousin, voice actor and director
Justin Cook, helped to gain him his first role. He started voice acting at nine years old, where he voiced
Hiro Sohma and the young
Akito Sohma in
Fruits Basket (2001). When Dismuke was twelve years old, he was given his first lead role as
Alphonse Elric in
Fullmetal Alchemist. In
Fullmetal Alchemist: Brotherhood, his role of Alphonse Elric was replaced by
Maxey Whitehead due to puberty, but he returned to reprise his role in the
live-action film on Netflix. Reflecting on his early acting career, Dismuke said: ''"I definitely didn't spend my early twenties feeling like a washed-up has-been pseudo-child star. In truth, I'm one of the lucky few in this business who've had something approaching job security thanks to my getting cast in a number of awesome shows that keep coming back for new seasons."'' He also voiced the young
Van Hohenheim, the Elric brothers' father in
Fullmetal Alchemist: Brotherhood. He is also the voice of many characters such as Chihiro Furuya in
Sankarea, Gen Narumi in
Kaiju No. 8, Lucifer in
The Devil is a Part-Timer!, Arslan in
The Heroic Legend of Arslan, Twelve in
Terror in Resonance, Shun Asanaga in
Endride, Hayashi in
Recovery of an MMO Junkie, Leonardo Watch in
Blood Blockade Battlefront,
Van Fanel in
The Vision of Escaflowne,
Senku Ishigami in
Dr. Stone, and Miyuki Shirogane in
Kaguya-sama: Love Is War. In 2016, Dismuke was cast in his first role in western animation as Oscar Pine in the
Rooster Teeth animated series
RWBY. In 2017, he was cast as Yukiya Naruse in
Code Geass: Akito the Exiled. In 2018, he was cast as Tamaki Amajiki in
My Hero Academia. In 2019, he was cast in his second role in western animation as Beetle in a Cartoon Network series
Beetle + Bean. In 2022, Dismuke wrote on
X that he would be stepping away from his voice acting work due to COVID-19 and subsequent vocal rest, which required him to temporarily step back from roles such as Miyuki Shirogane in
Kaguya-sama: Love is War (which
Clifford Chapin filled in his absence) and Nishikata in
Teasing Master Takagi-san (which
Bryson Baugus filled in his absence). Dismuke later revealed that he had
muscle tension dysphonia. Dismuke received treatment and was assured that his vocal chords were not damaged. ==Filmography==
