One popular Stranger Things cast fanfiction might be those that focus on the friendship between the kids off - screen. For example, stories about how they bond during filming breaks and play pranks on each other. Another type could be romantic fanfictions that pair different cast members in fictional relationships, like a story where Eleven and Mike's actors have a secret off - screen romance. There are also fanfictions that explore the cast's adventures in a modern - day setting outside of the Stranger Things universe, like them going on a road trip together.
Archive of Our Own (AO3) is a great place to start. It has a large collection of Stranger Things fanfiction, including those focused on the cast. There are various tags you can use to filter and find the specific type of cast - centered stories you're interested in. Another option is Fanfiction.net, which also has a decent amount of Stranger Things cast fanfiction. However, the quality may vary more compared to AO3.
Yes, there are. The Stranger Things comics offer additional adventures and backstories that complement the TV series. They provide more depth to the Stranger Things universe.
Well, time travel is a cool theme. Some fanfictions might have the characters going back in time to prevent certain events in the show from happening, like the opening of the gate to the Upside Down. Then there's the theme of alternate universes. Imagine a universe where Eleven was raised by Brenner in a completely different way. And of course, the theme of romance. You can find a lot of fanfictions about Mike and Eleven's relationship, but also other possible pairings among the characters.
