Early Life & Background
Kieran Regan was born on August 20, 1998, in San Clemente, California. Public information about his childhood and family is relatively limited, but Regan has shared an unusual detail about growing up: he is a twin. On his official website, he recalls his grandmother joking that he would live his life at “Mach two, hair on fire,” a description that fits the energetic personality he brings to his professional work.
Acting was not originally the plan. During college, Regan was pursuing graphic design and photography. His professor, David Ruis, encouraged him to audition for acting roles after noticing his public-speaking ability. That suggestion changed the direction of his career. Regan eventually earned a degree in graphic design while building experience as a performer.
His theatrical background included university productions such as As You Like It and The Christians, giving him stage experience before voice acting became a much larger part of his professional life.
Career Journey & Breakthroughs
Regan’s professional career began expanding around 2020, with work covering theater, commercials, animation, dubbing, audiobooks and video games. He built a particularly strong connection with anime dubbing and Los Angeles voice-production studios.
One of his early anime credits was Yusei Suenaga in AMAIM Warrior at the Borderline. He later appeared in titles including LBX Girls, Good Night World, The Rising of the Shield Hero, Blue Box, Tokyo Revengers, The Prince of Tennis II and Ascendance of a Bookworm.
A major breakthrough arrived with Shikanoin Heizou in Genshin Impact. Regan officially confirmed the role in July 2022, and the character quickly became one of his signature performances.
His game résumé has continued to grow. He voices Butter Roll Cookie and Starchy the Moletato in Cookie Run: Kingdom, Montague in Fortnite, and has worked on titles including Arknights, Pokémon Masters EX and Tower of God: New World.
Anime fans may know him particularly well for Shinn Asuka in Mobile Suit Gundam SEED Freedom. Regan took over the English role for the 2024 film, replacing Aaron Phillips, and his performance put him at the center of one of the most recognizable Gundam releases of the period.
He returned as Fohl for The Rising of the Shield Hero and has continued working across both anime and games. In 2025, he voiced Andy Bogard in Fatal Fury: City of the Wolves, with SNK officially confirming him as the character’s English voice actor.
More recently, Regan voiced Junya Azuma in Takopi’s Original Sin. Crunchyroll confirmed the complete English cast when the dub began streaming in January 2026.
His 2026 credits also include Koto Okotteru in Cosmic Princess Kaguya! and Locke in League of Legends, showing how his work is moving well beyond traditional anime dubbing.
Regan was also nominated for LGBTQ+ Voice Actor of the Year at the 2025 Gayming Awards, alongside performers including Erika Ishii, Ciarán Strange and JP Karliak.
Body Stats & Physical Appearance
Regan’s professional casting profile lists him at 5 feet 8 inches (173 cm) and around 170 pounds (77 kg), with brown hair, blue eyes and an athletic or toned build. His listed playing range is approximately 16 to 27, which reflects the youthful character types frequently associated with his voice work.
His own professional materials emphasize a broad vocal range, including character, commercial, audiobook and narration work. He also operates a broadcast-quality home studio equipped for remote recording.
Scandals, Controversies & Media Headlines
There are no major verified scandals or controversies associated with Regan that warrant inclusion in a biographical profile.
Most media coverage has focused on his expanding résumé, particularly his casting in Genshin Impact, Gundam SEED Freedom, Fatal Fury, Takopi’s Original Sin and other major productions.
The most recent personal headline is positive rather than controversial. In September 2026, Regan announced that he and his partner Richard are engaged.
Personal Life, Hobbies & Relationships
Regan keeps much of his private life away from traditional entertainment coverage, but his professional biography gives fans plenty of clues about his interests.
Photography remains an important part of his life. He describes himself as a devoted film photographer and says he had a gallery at 19. His interests also include gaming, with his website joking about his competitive streak in mobile Tetris and cribbage.
Another performer profile lists rock climbing, rugby and photography among his interests, while also describing him as a dog lover and an avid RPG player.
Outside acting, Regan has developed a substantial career as an audiobook narrator, particularly in YA, LitRPG, romance and LGBTQ+ fiction.
