Stranger Things Introducing New Girl in Season 2 — Is She Eleven's Sidekick... или Successor? 

was fast. Less than 24 hours after Netflix officially renewed 

 for Season 2, casting is already underway on the 9-episode sequel. And it would seem Mike, Dustin, Lucas and Will are about to make a new girl friend.

Stranger Things Season 2: Watch the First Teaser

According to casting intel obtained by TVLine, series creators Matt and Ross Duffer are introducing three major new characters, one of whom, “Max,” is a “tough and confident” 12-14 year-old female whose “appearance, behavior and pursuits seem more typical of boys than of girls in this era.” Max eschews Hawkins’ primary mode of transportation — the bicycle — for a skateboard, which she uses to get around everywhere. Interestingly, the Season 2 premiere title, as teased in the renewal news video, appears to be “MadMax.”

The role is likely to raise eyebrows in light of the Duffer Brothers’ telling EW.com that while most Season 1 characters are poised to return in Season 2, Eleven’s involvement remains “up in the air.”

The other two new regulars include Max’s “very muscular and hyper-confident” Camaro-driving older brother Billy, and the thirtysomething gender-neutral role of “Roman.” The latter character suffered a great loss at an early age and has been seeking revenge ever since. (

As we reported Wednesday, Season 2 — which arrives in 2017 — will pick up about a year later, in the fall of 1984.
