Netflix original Stranger Things season 2, which is set to premiere on Halloween this year, will introduce a new villain in the new season. And, this new villain is no monster but a human named Billy.

Stranger Things director Shawn Levy said the new villain is scarier than any other monster or Demogorgon. "He is a mean guy," director Shawn Levy said as per a report of TV Guide. "He has prejudices that are ugly. He treats his younger sister in a mean, controlling, bully-ish, domineering fashion. So he's just bad."

The Duffer brothers explained their reason behind this new addition to the Stranger Things family as "it was important to us to have a human villain in there that could disrupt the lives of our characters," Ross Duffer said. "And Billy, really, he disrupts the world the teenagers and stuff."

Adding to this, the new season is going to be a lot darker or horror-oriented as the actor Finn Wolfhard (Mike Wheeler) said to PEOPLE in an exclusive interview. Apart from all the villains, Upside Down will have a major role in this season as Ross Duffer recently told E! News, "I will say that the threat that is introduced this season is something that will carry over for more than just this season, so it will become sort of our main villain, shall we say, for the show."

The show creators Duffer Brothers previously spilled the beans on the season 2 in Variety's podcast Remote Controlled. One of the fan-favourite characters Barb (Shannon Purser) will not reprise her role in the forthcoming season.

The second season will see the same old faces from the first season including Finn Wolfhard as Mike Wheeler, Millie Bobby Brown as Eleven, Gaten Matarazzo as Dustin Henderson, and Caleb McLaughlin as Lucas Sinclair.
