Yeah it's probably a berserker, it was even mentioned twice BY Chris Argent in Season 3B. He said they wear animal skins and they get stronger as a result, but it makes them go crazy like a werewolf on a full moon.

He also said that it took a few hunters to bring it down, so it might not be as strong as it looks, Scott's pack is bigger and stronger, so we'll see.

It appears they changed Kate's makeup....That's good, she looks scarier. In fact, I'm not 100% sure THAT IS Kate.

As for the guy with no mouth, I'm pretty sure he's The Benefactor, and he may not be a bad guy or villian or the big bad b/c the actor did indeed say they are keeping him on the show.
