Stranger Things will return to Netflix for a final season but there will be no new characters as the series comes to an end. The Duffer brothers, who are the showrunners and executive producers, confirmed the news in an IndieWire interview, saying they’d focus on the existing cast instead. 

“Whenever we introduce a new character, we want to make sure that they’re going to be an integral part of the narrative”, Ross Duffer said, adding, “But every time we do that, we’re nervous, because you go, ‘We’ve got a great cast of characters here, and actors, and any moment we’re spending with a new character, we’re taking time away from one of the other actors.’ So we’re just very, very careful about who we’re introducing.”

Matt echoed these thoughts saying they’d avoid putting too many characters into the mix in the final season. 

“I just like shaking it up, so we shake it up by changing the plot or adding in a new monster. We’re doing our best to resist [adding new characters] for Season 5. We’re trying not to do that so we can focus on the OG characters, I guess”, he said. 

Stranger Things has had a good run with new characters. Some of them, like Bob and Dr Alexei managed to pull at viewers’ heartstrings, especially when the narrative called for their sacrifice. Others like Murray and Yuri have managed to give audiences their share of laughs.

However, the best addition has to be Joseph Quinn’s Eddie Munson in Season 4, who quickly skyrocketed to become a fan-favourite with his fascination for Dungeons and Dragons and a very healthy taste in metal

The final season will see the heroes reunited in Hawkins as the portal to the Upside Down has opened. The fight against Vecna is on after the antagonist took a hit last season but managed to survive. With the Upside Down bleeding into the real world, there’s a good chance that the Mind Flayer will be back in the fray as well.
