Stranger Things: 10 Best Supporting Characters

Lucas’s younger sister, Erica Sinclair (Priah Ferguson) has quickly become a large part of Stranger Things and another reason of why the Duffer Brothers’ show is so fantastic.

First appearing in the second season, Erica was a sassy comic relief character who would constantly berate her older brother and his friends for being massive nerds. Though she never had much to do with saving Hawkins, she was always a delight whenever she appeared onscreen.

It wasn't until the third season that Erica had a much bigger role to play. She became part of the Scoop Troop alongside Dustin, Steve, and Robin to help save the town and put a stop to the Russian experiments going on underground – though it took a lot of free ice cream to persuade her to help.

It was as this point where her no-nonsense personality could shine through. She was as hot-headed and hilarious as ever, and she bounced-off great with Dustin. But the biggest defining moment for her was realising that she, too, was a massive, My Little Pony-loving nerd.

You can’t spell “America” without “Erica”, after all, and we can’t wait to see what role she’ll play in the next season.
