Riverdale brings on Chris O'Shea as "manipulative, powerful and increasingly dangerous" new character

Deadline

The You and Madam Secretary alum will play Percival Pickens, Riverdale's newest resident. "Although he presents as charming (and is), Percival’s also manipulative, powerful and increasingly dangerous as he comes into conflict with our characters, most especially Archie," according to Deadline. "A descendent of one of Riverdale’s founding fathers, General Pickens, Percival wants to turn Riverdale into a 'utopia,' a dark agenda he pursues quietly but ruthlessly."
