Teen Wolf's Dread Doctors are in Beacon Hills to stay.

'Teen Wolf' Season 5 Spoilers: How Many Dead Will Walk In The Premiere? Aiden Isn't The Only Returning Character

The MTV drama usually concludes each season with the dissolution of the most recent big bad, but season 5's ghoulish scientists will stick around well past the summer finale.

"These are our only villains that carry on to the next season," Tyler Posey (Scott) ominously told E! Online.

By next season, Posey is of course referring to season 5B, not an unannounced sixth season.

Don't worry about getting bored, however. Teen Wolf isn't about to let its heroes (or viewers) grow complacent - these MDs will have a few transformative tricks up their sleeves.

"They have another [season], they will carry on because they will evolve," director Russell Mulcahy explained, according to E! Online. "The real teaser, which won't be revealed until next season, is what's behind the mask."

The question MTV has to ask its self is, are Teen Wolf fans going to be that patient? Scott's pack of supernatural beings has quite a strong following, but the series always runs the risk of not retaining ratings while playing the long game.

Find out if the Doctors are as intriguing as we hope when Teen Wolf returns to MTV for a two-night premiere on June 29 and 30.
