Core Child Ensemble: Leading the Hawkins Crew
Eleven / Jane Hopper (Millie Bobby Brown)

Dustin Henderson (Gaten Matarazzo)
Gaten Matarazzo plays Dustin, the inventive, humorous member of the group known for his Demogorgon mask and catchphrases. His storylines explore loyalty, courage in the face of fear, and growing up. Matarazzo’s upbeat delivery makes Dustin a fan favorite throughout the series.
Lucas Sinclair (Caleb McLaughlin)
Caleb McLaughlin brings Lucas, the skeptical yet fiercely protective friend who often challenges plans and prioritizes safety. His pragmatic streak creates tension but also balance within the core group. McLaughlin has emphasized focusing on character truth amid escalating supernatural stakes.
Max Mayfield (Sadie Sink)
Sadie Sink plays Max, the skateboarding, sarcastic new girl who joins the Party in Season 3. Her story tackles grief, family conflict, and the burden of being ‘the emotional anchor.’ Sink portrays resilience amid ongoing danger in Hawkins.
Will Byers (Noah Schnapp)
Noah Schnapp originated Will, the sensitive boy who experiences episodes of missing time and distress after being pulled from the Upside Down. His portrayal captures trauma, vulnerability, and gradual empowerment as Will confronts fear and self-doubt across seasons.
Ben Hanscom (Joe Keery)
Joe Keery plays Steve Harrington, who evolves from a stereotypical high school bully to a caring, resourceful babysitter and unofficial protector of the kids. Keery’s comedic timing and warmth make Steve’s redemption arc one of the series’ enduring elements.
Teen and Young Adult Characters

Jonathan Byers (Charlie Heaton)
Charlie Heaton plays Jonathan, Nancy’s brother and a quiet, principled photographer documenting strange occurrences. Heaton’s restrained performance emphasizes integrity and loyalty, even as Jonathan navigates danger and loss.
Steve Harrington (Joe Keery) Continued Arc
Beyond the kids, Steve remains a touchstone for fans, blending humor with genuine care. Keery’s consistent presence bridges the younger and older ensembles, and his character’s growth from antagonist to ally is frequently cited as one of the show’s strengths.
