Frank Stallone is not primarily known as an anime voice actor. He is an American actor and singer-songwriter who has worked extensively in live-action film and television since the mid-1970s. His most recognized voice role in animation is that of the Decepticon criminal Thunderhoof in the animated series Transformers: Robots in Disguise. The series, which aired from 2015 to 2017, is an American production and part of the broader Transformers franchise. In this show, Stallone voiced Thunderhoof, a character depicted as an elk-themed crime boss who speaks with a distinct mobster accent. Stallone portrayed this role throughout multiple episodes of the series. Beyond this single character, the available information does not document any other major voice roles for Stallone in anime or related animated productions, nor does it provide evidence of recurring collaborations with specific voice directors or studios, or notable achievements specifically within the field of voice acting. Stallone is more widely known for his work in front of the camera and as a musician, having contributed to film soundtracks including his song Far From Over from the film Staying Alive. As a result, his career in animation voice-over appears to be extremely limited.
