Archie (KJ Apa) has yet another nemesis on Riverdale. TV Guide has learned that Claws alum Juan Riedinger is heading to the murder-filled small town in Season 4 to be the next to torment our ginger hero.

Riedinger will play Dodger, Archie's new arch-nemesis. Once again, it seems that Archie is picking fights with adults rather than doing his homework. You'd think that after pissing off a mob boss in Season 2 and having a serial killer dressed as a Gargoyle King torment his friends in Season 3 that Archie would be more interested in high school pranks and prom than starting more beef, but the kid is headstrong.

Unfortunately, before Archie can get into any trouble with Dodger, Riverdale will have to address the absence of Fred Andrews (Luke Perry). The Season 4 premiere will be a tribute to Fred in that wake of Perry's untimely death last spring. Perry's Beverly Hills, 90210 cast mate Shannen Doherty will also join the premiere to help pay tribute to her friend.

Deadline was the first to report the news.

Riverdale Season 4 premieres Wednesday, Oct. 9 at 8/7c on The CW.
