Main

• Andrew Rannells as Archie Andrews – a redheaded, freckled student at Riverdale High, and a reporter for the school newspaper. All of his news stories are centered around the surreal occurrences that take place within each episode and always end with "...in a little town called Riverdale." Despite his clumsiness and rash decision-making, he frequently attracts girls, human or otherwise.
• America Young as Betty Cooper – a literal girl-next-door who is intelligent, comely, cute, level-headed, caring, and the head of the cheerleading squad. She is best friends with Veronica, despite them both competing for Archie's affection. She has bright blonde hair that's always worn in a ponytail.
• Camille Schmidt as Veronica Lodge – a beautiful, rich, popular, and somewhat self-centered girl. She is best friends with Betty, with whom she also shares a rivalry for Archie's affection. Although both of them are frequently the target of Reggie's advances, Veronica is targeted somewhat more often. Her hair appears black, but she is described as a brunette in the show.
• Chris Lundquist as Jughead Jones – Archie's eccentric yet insightful best friend who almost always has food on his mind, especially hamburgers. He generally does not like girls, although he is close friends with Betty, and he often butts heads with Veronica and Reggie. This version owns a litany of pets throughout the series, most notably Hot Dog, who is just as lazy as he is. Jughead usually wears a gray whoopee cap on his head, covering his choppy black hair.
• Paul Sosso as Reggie Mantle – an egotistical, aloof, prank-prone jock who has a one-sided crush on Veronica and is frenemies with Archie. He is generally the most disliked member of the group. In this particular incarnation, he has a niece named Amy.
• Ben Beck as Dilton Doiley – a bespectacled, nerdy genius who is friends with Archie and the others. His inventions usually help save the day, although they are sometimes the cause of the titular weird mysteries. In this incarnation, he does most of his work in the school lab ("Invisible Archie" reveals that this is a reward for his exceptional grades), where he is often isolated from his peers and all but lacks a social life. His catchphrase is, "I'll be super amalgamated!"

• Mr. Fisk – the CEO of ZoomCo who, after discovering that his Zoom energy drink contains a mutant formula that causes some people to mutate into monsters, tries to bribe and stop Archie from telling the world on national TV. He convinces Archie not to tell the news, as doing so would destroy his company and many people's jobs.
• Olga Karpuchi – the shy but intelligent civilian identity of a superheroine, named Supreme Girl. Her enemy is the villainous Dr. Arachnid, and they both hail from the Twelfth Dimension. During her stay at Riverdale High, she works with Archie on the school newspaper and has a crush on him. She only physically appears in "Supreme Girl vs. Dr. Arachnid," but is first mentioned in "The Jughead Incident."
• Robbie Dopkins – a friendly boy on Riverdale High's athletic team, who debuts in "Invisible Archie," where he enamors both Betty and Veronica due to his muscles.
