When "Teen Wolf" season 5 returns on air, Scott and his pack will have to reunite to take on not one but two mega dangerous enemies. However, rumor has it that a third villain will be on a rampage and this new baddie will allegedly be Stiles himself.

There's word going around that Stiles will go evil when the show returns. This is owing to the changes in his body that reports say he may no longer be able to control. But so far, Stiles isn't doing bad in containing these changes so if Stiles will be something in the second half of the season, he will be a hero to Malia.

In the trailer for the "Teen Wolf" season 5B, it is shown that Stiles will be storming into the Eichen House to save Malia. This should give way to a more romance-inclined midseason premiere that executive producer Jeff Davis has long promised.

However, Stiles and Malia have tons of problems to face come the latter half of the season. One of which involves the The Desert Wolf, who will work with Theo to make Malia suffer. The entrance of this baddie is expected to give a free rein to the darker sides of both the characters that fans haven't seen before. 

Meanwhile, in "Teen Wolf" season 5b, Scott and the gang will be tackling the Beast of Gevaudan, a killer werewolf famous and feared for its ferocity. For Theo though, the arrival of the sharp-clawed monster is the perfect opportunity to get stronger and fully transform into a werewolf.

Word on the street is that Theo will attempt to harness the beast's power for himself. In order to do so, he will get some help from Deucalion. It remains to be seen if Theo will be successful in pilfering the historical creature's powers as there are reports that Deucalion will cross to the side of the good soon.

"Teen Wolf" season 5 returns on MTV on Jan. 5.
