Who are the main cast members of Riverdale?

Core six actors and their characters

The series’ foundation rests on six actors who appeared in all seven seasons. KJ Apa portrays Archie Andrews, the all‑American musician and protagonist. Lili Reinhart plays Betty Cooper, the aspiring journalist with a hidden edge. Camila Mendes is Veronica Lodge, the sophisticated newcomer from New York. Cole Sprouse rounds out the core four as Jughead Jones, the narrator and writer. Madelaine Petsch plays Cheryl Blossom, who evolves from antagonist to close ally. Casey Cott appears as Kevin Keller, Archie’s best friend and the town’s sheriff’s son. (The CW official show page)

Supporting main characters over the seasons

Beyond the core six, several actors were elevated from recurring to main cast. Vanessa Morgan joined as Toni Topaz, later promoted to a central role. Erinn Westbrook entered in season 5 as Tabitha Tate, Jughead’s love interest. Drew Ray Tanner played Fangs Fogarty and became a regular in later seasons. (Wikipedia – list of characters)

The pattern: The core remained remarkably stable; only the supporting ensemble changed significantly as the series shifted tone and setting.

Who is in the cast of Riverdale season 1?

Original main cast

Season 1 introduced the core six as regulars: KJ Apa (Archie), Lili Reinhart (Betty), Camila Mendes (Veronica), Cole Sprouse (Jughead), Madelaine Petsch (Cheryl), and Casey Cott (Kevin). Also featured as main cast in the first season: Ashleigh Murray as Josie McCoy, leader of the Pussycats, and Marisol Nichols as Hermione Lodge, Veronica’s mother. Skeet Ulrich appeared as FP Jones, Jughead’s father, initially recurring then main in season 2. (Us Weekly)

Notable recurring characters in season 1

Luke Perry played Fred Andrews, Archie’s father, in a central recurring role. Mädchen Amick appeared as Alice Cooper, Betty’s demanding mother. Ross Butler played Reggie Mantle in a recurring capacity before departing. (The CW official show page)

Why this matters: Season 1’s cast set the template for the entire series — a blend of archetypes from Archie Comics with darker, more complex personalities.

Who plays Jason in Riverdale?

Trevor Stines as Jason Blossom

Trevor Stines portrayed Jason Blossom, Cheryl’s twin brother whose murder in the pilot kicks off the show’s central mystery. Stines appeared in flashbacks and dream sequences across the first season and sporadically later. (Wikipedia – Riverdale characters)

Jason’s role in the plot

Jason’s death is the catalyst for the entire series. His drowning at Sweetwater River triggers an investigation that exposes the town’s secrets. The character remains a symbolic presence even after the mystery is resolved. (Us Weekly)

The implication: Jason’s murder remains the narrative engine even after the mystery is solved, a testament to the show’s commitment to its origin.

Who plays Reggie in Riverdale?

Recasting of Reggie Mantle

Reggie Mantle was portrayed by two different actors. Ross Butler played the role in season 1 as a recurring character. Charles Melton took over from season 2 onward, eventually becoming a main cast member in season 3. (Us Weekly)

Charles Melton as Reggie (seasons 2–7)

Melton’s Reggie developed into a more prominent character, serving as a love interest for Veronica and later a rival turned ally to Archie. (The CW official show page)

Ross Butler as Reggie (season 1)

Butler’s Reggie appeared in a handful of episodes as a minor antagonist. The recast was due to Butler’s commitments to the series 13 Reasons Why. (Us Weekly)

The trade-off: Recasting allowed the character to have a longer arc, but fans who preferred Butler’s portrayal missed the original continuity.

How has the cast of Riverdale changed over the seasons?

Departures after season 3

Several original cast members left around season 3. Ashleigh Murray exited as Josie McCoy to lead the spinoff Katy Keene. Luke Perry died in 2019; his character Fred Andrews was written out with respect. Marisol Nichols departed after season 2, though she returned for guest spots. (Us Weekly)

Additions in later seasons

Vanessa Morgan (Toni Topaz) was promoted from recurring to series regular in season 3. Erinn Westbrook joined as Tabitha Tate in season 5. Drew Ray Tanner (Fangs Fogarty) became a regular in the final seasons. (Wikipedia – list of characters)

Main cast consistency

The core six — KJ Apa, Lili Reinhart, Camila Mendes, Cole Sprouse, Madelaine Petsch, and Casey Cott — remained through all seven seasons. This stability gave the series a sense of continuity even as plotlines grew increasingly outlandish. (The CW official show page)

What this means: The show’s willingness to recast and promote supporting actors kept the ensemble fresh, but the unshakeable core was the reason viewers stayed invested.

Which characters are in Riverdale season 7?

Returning main characters

For the final season, all six core actors returned. The season also featured Madelaine Petsch as Cheryl, Vanessa Morgan as Toni, Charles Melton as Reggie, and Erinn Westbrook as Tabitha. The entire main cast appeared in the 1955 time‑jump setting. (The CW official show page)

New characters in the final season

Season 7 introduced 1950s versions of familiar townspeople and a handful of new faces, including a time‑shifted Julian Blossom and several minor characters from Archie Comics. (Wikipedia – list of characters)

The catch: While the core cast remained intact, season 7’s retro premise required all actors to play alternate versions of themselves, adding a fresh dynamic to the farewell.

Six main characters, one pattern: the core quartet plus Cheryl and Kevin formed the show’s steel spine, while the adult and supporting cast rotated around them.

The implication: While the lead quartet never wavered, the supporting cast’s evolution — especially the Reggie recast and the promotions of Morgan and Westbrook — gave the show a dynamic that kept it from feeling stale.

The casting of the core four was always about finding actors who could embody the spirit of the Archie Comics while bringing something new to the screen.

Roberto Aguirre‑Sacasa, Showrunner

Playing Archie for seven years was a once‑in‑a‑lifetime experience. The character grew up alongside me, and that doesn’t happen often.

KJ Apa (Archie Andrews)

For the cast, the end of Riverdale season 7 marks not just a conclusion but the start of new chapters. The show launched careers, reimagined beloved comic characters, and proved that a small‑town mystery could hold a core ensemble together through seven wildly unpredictable seasons. For KJ Apa, the legacy is a place in one of television’s most committed ensemble experiments.
