Michael Peña’s Rainbow Six is a rumored Prime Video series that would spin off of the final season of Tom Clancy's Jack Ryan. In the final season of Prime Video and John Krasinski's first Tom Clancy adaptation, Jack Ryan needed to bring in professionals with specialized skill sets — most notably Domingo "Ding" Chavez, played by Pena. Ding is a member of the CIA who is part of the overarching Tom Clancy universe, an agent who goes on several missions in the books and the video game series as the executive officer of Rainbow Six. He appeared in 22 novels from the larger universe Clancy created, including seven from the core Jack Ryan novels.
