Ok so basically every member of the cast has already been suspected here, except for the one I had in mind, so here I go with my hypothesis:

Peter Hale is the Beast.

Now that might sound pretty stupid at first, most of all because all other chimeras are teens, and were no mystical creatures before the Dread Doctors got them, but normal humans. But think about it:

In the last episode (15) Deacon told the pack, that Dr. Valack found a way to amplify the power of creatures in the past, and that he's at it again. Now what do you think would happen, if you amplified the abilities of a guy who even without amplification becomes a giant monster-werewolf when transformed? Something even bigger! And if you had the knowledge and equipment of the Dread Doctors, you might be able to get even better results (like a black-steaming murderous, gigantic monster-werewolf... reminds you of something?). Besides that Peter Hale is a resident of Eichenhouse since the end of season 4, so it would be pretty easy for Valack to experiment on him. Also Peter went mad after looking into Valacks third eye, so it makes sense that he would need to be reminded of who he is.

Now obviously this is not enough to support my speculations, but what if I add this: it's been said, that the Dread Doctors found the clue to resurrect the Beast during the Supermoon. And what creatures tend to react in wierd ways to the supermoon, and become way stronger during that time, and also way more aggressive and full of killing-intent? Werewolves! So what if Peter, who already had a hole in his head that amplified his powers, was exposed to the supermoon's influence, became even stronger and crazy violent, and the Dread Doctors realized that at this point, he was only an incredibly small step away from gaining power equal to the Beast?

... so yeah, that's it from my side, tell me what you think!

Also (and that's less of an argument, just an observation that I'd find pretty funny if my theory came true) until now all villains from the previous seasons reappeared somehow (Gerard, Kanima - as one of the Chimeras, Deucalion, Meredith, Werejaguar - as one of the Chimeras, Berserker - as one of the Chimeras) and the only ones missing would be Void-Stiles and Peter.
