Roy is an older man with a thick mustache and bushy eyebrows. His attire consists of a professional white long-sleeve dress shirt with a tie, and a sweater vest over it. He also wears a newsboy cap when on the streets, which covers his short, swept-back hair.
As a veteran journalist, Roy has come to accept and conform to the restrictive nature of the monarchy, fearing retaliation for defiance.
Roy is first seen investigating the aftermath of a battle between the Scout Regiment and the Military Police First Interior Squad in Trost District, along with the inexperienced journalist Peaure. Although he learns of everything that transpired, Roy obeys Nile Dawk's command to not mention the Interior Branch's involvement.
Roy and Peaure later witness three members of the Military Police reveal that the MPs were responsible for Dimo Reeves's murder. Roy is reluctant to report what he has witnessed, but he is convinced after being confronted by Peaure and Flegel Reeves that the monarchy does not care about the people living inside the Walls and that if the Titans get in, they will let him and his family perish.
Roy is among the citizens to greet the Scouts upon their return from Shiganshina.
Roy and Peaure meet with Hange and Levi to discuss the revelations from Eren's basement which have been released to the public. When Hange asks Roy about the reactions of the people, he tells her they are various and that everyone is confused. Hange says that they will let the taxpayers decide what to do with that information, prompting Roy to state that he is proud of what all the Scouts have done. He tells her that they are glad to help the Scouts as they can, but are also worried about the future of the Walls' inhabitants.
