James Ryan Haywood was an employee of Rooster Teeth Productions and voiced Caboose's lieutenant John Elizabeth Andersmith in seasons 12, 13, and 15 of Red vs. Blue. He also voiced Marlowe in the Season 14 episode Grey vs. Gray and briefly voiced Diesel in the RTX@Home version of Viper, the first episode of Red vs. Blue: Zero. Previously, he worked as part of the animation staff for Red vs. Blue: Season 10.
He is well known for his work with Achievement Hunter, alongside Geoff Ramsey, Jack Pattillo, Gavin Free, Michael Jones, Lindsay Jones, and Ray Narvaez, Jr. His other work with Rooster Teeth includes voice acting for Professor Port in the web series RWBY, as well as regular appearances on the gaming podcast The Patch and, its reboot of sorts, "Glitch Please".
He left Rooster Teeth on October 6, 2020, following numerous sexual misconduct and grooming allegations. Shortly afterwards it was announced Red vs. Blue: Zero would delay its release date from October 19, to completely re-record Haywood's dialogue in the series.
