15. Jonathan Byers

Actor: Charlie Heaton

Misunderstood and broody, Jonathan Beyers remains a fan-favorite thanks to his big heart, his love for Nancy and his deep bond with Will. A bond which, like Joyce, brings him to do anything he can to help his brother, regardless of the danger.

He and Joyce bring a whole new definition to the word ‘family’, the kind that just doesn’t care if it takes defeating a giant monster and its babies to get their loved ones back.
