In the second part of "Teen Wolf" Season 5, a new villain will be coming to Beacon Hills which will force the Pack to set aside their differences in order to defeat it.
According to Youth Health Mag's sources, the new villain will be called The Beast, and it was reported that the new big bad will be so strong that Scott (Tyler Posey) will need more hands to keep it down. With that, it was also revealed that Deucalion (Gideon Emery) will be returning to help the Pack. Deucalion may be the bad guy in Season 3, but it appears that he will be lending a helping hand to the Pack to defeat the big bad guy in the upcoming second part of Season 5.
It was also revealed that aside from facing a new villain, some of the characters of the show will be having their own personal troubles in the second part of the season. In the trailer for the return of Season 5, Kira (Arden Cho) can be seen being stuck in the middle of the desert and needs to figure out a way to get back to Beacon Hills. Meanwhile, Stiles (Dylan O'Brien) will have to look for a way to help Lydia (Holland Roden) escape from the Eichen House.
In other news, Movie Pilot reports that creator Jeff Davis talked about his plans for Season 6 and his reaction to a possible "Teen Wolf" movie. In the interview, Davis revealed that they still don't have anything concrete for Season 6 because they are looking at two different storylines, and it could be a two-season deal.
Many speculate that this could mean that the show will run up to Season 7. When asked about a movie, he said that it is still not on the table but added that he would love to write for a "Teen Wolf" movie in the future.
