"Teen Wolf" season 5 spoilers suggest that Scott McCall will be having his hands full with a whole new villain. It would appear that the Pack will have to set aside their differences and work together in order to keep the new enemy at bay.
As Christian Post has reported, this new villain is called the Beast. This new enemy is going to be so strong that it will most likely take more than Scott, played by Tyler Posey, to keep it down. That said, "Teen Wolf" season 5 spoilers have also indicated that Deucalion, played by Gideon Emery, will be returning to be of help to the Pack.
Although Gideon was a villain in the MTV show's third season, it would appear that he will be lending his hand to the group in order to successfully steal the powers that the Beast possesses.
In addition to having to defeat the Beast, the show's characters will also be troubled by their own personal struggles. For instance, the trailer showed Kira, the character that Arden Cho portrays, stuck in the middle of the desert. She will have to figure out a way to get away from the morgue and make her way back to the Pack at Beacon Hills.
Stiles, played by Dylan O'Brien, is also going to face his own problems. He will try to help Lydia, played by Holland Roden, escape from the Eichen House. He is expected to turn to Shelley Hennig's Malia for assistance. Sadly, however, she cannot help him with his problem.
Amidst all these struggles, a "Teen Wolf" romance will turn awry. Parris, played by Ryan Kelley, and Lydia were spotted in a bizarre situation. While they were making out, Lydia suddenly noticed that she was covered in blood. However, it remains unknown whether this scene was part of her dream or not.
