Rio Durant is an Ardennian pilot on Beckett's crew, voiced by Jon Favreau in Solo: A Star Wars Story (2018). StarWars.com describes "a diminutive, four-limbed Ardennian" and "a longtime associate of Tobias Beckett and Val" who is "a capable pilot, a skilled tactician, and a lover of good stories", seeing each new scam as "a chance to write a new tale".
That last detail is the character. Rio is the only person in the film who is enjoying himself, and the film kills him during the Vandor heist specifically to end that mood. He is also a useful reminder that the crew is a workplace rather than a family — nobody stops to mourn, because the job is still running.
