Brian Beacock is an American television and film actor and a voice actor in anime and video games. He is perhaps best known for playing Byonko in Zatch Bell!, Takato Matsuki in Digimon Tamers, Yamato Delgado in Battle B-Daman, and Agumon in Digimon Data Squad. He voices Théo Barbot in the English dubbed version of Miraculous: Tales of Ladybug & Cat Noir.
- Brian also voices several skeletons and Calico in Zak Storm: Super Pirate, another ZAG Heroez show.
- Despite Théo has a speaking role in both "Gigantitan" and "Sapotis", Brian didn't voice him in those episodes and instead it was Ezra Weisz. This likely happened because Théo's character model has been reused in some episodes of Season 2 and thus he played a minor role in both episodes he spoke similar to that of a background character. Though, Brian returned to voice Théo again in "The Puppeteer 2".
- When Théo gets akumatized into Copycat, he's voiced by Bryce Papenbrook whenever he is imitating Cat Noir.
