Be afraid, Teen Wolf fans. Be very afraid.

A few days after MTV released a brief promo that teased a couple new villains on Teen Wolf Season 4, the network has now come out with the first full-length trailer for new summer episodes...

... and they look frighteningly fantastic.

Specifically, the 90-second trailer provides us with our first look at the season's main big bad, a character known as The Benefactor, along with shots of Papa Argent taking on a fatherly role with Scott and a lot of awesomeness involving Derek Hale. 

Check it out now!

Teen Wolf Season 4 kicks off on June 23 at 10/9c.

And if you need a refresher, you can always watch Teen Wolf online.
