9. Robin Buckley

Actress: Maya Hawke

It’s always great to add another member to our favorite team of youngsters! Robin easily became a likeable character throughout the mere 8 episodes of Season 3, thanks to her brave, badass and relatable characteristics.

Steve’s ice-cream parlor colleague not only proves she’s extremely useful (by solving codes, fighting those Russians and entering the Upside Down), but she’s also grabbed viewers’ hearts by coming out to Steve. We’ll be mad if anything happens to her next season!
