Ryan Simmons is a Canadian voice actor known for his work in anime series recorded in Alberta. He began his career in voice-over after graduating from the radio and broadcasting program at the Southern Alberta Institute of Technology in 2010. Working as a music director and announcer at a radio station in Red Deer, he pursued voice acting part-time, a decision influenced by learning that one of his former instructors had voiced a character in the Dragon Ball series.

His most prominent role is as the villain Ikazuchi in the English adaptation of the anime series Future Card Buddyfight. He voices the character across multiple seasons of the show, including Future Card Buddyfight 100, where Ikazuchi serves as a primary antagonist. Simmons has described the character as unbridled evil, noting that the role allows him to explore a darker, more theatrical side of his performance with manic shouting and laughing. The character's storyline involves a complex arc, including a heel-face turn, demonstrating the range required for the role.

In addition to his work on Buddyfight, Simmons has a recurring guest role as Takeru in the anime series Vanguard G. This role connected him with fellow Red Deer-based voice actor Keaton Whitbread, who voices the character Hayato, Takeru's on-screen brother. This collaboration highlights a local network of voice talent working in the Alberta anime dubbing industry.

Beyond these specific anime credits, Simmons has performed voice work for a variety of other media, including commercials, safety videos, and mobile applications. His professional voice is described as conversational, believable, and youthful, with a friendly and slightly raspy quality. He is noted for his ability to perform a wide range of characters and accents. His work in animation has been made accessible to a broad audience through platforms such as YouTube, Hulu, and Netflix.
