Berserker

Berserkers are men who wear the skins/bones of bears within the Teen Wolf Universe.

According to Chris Argent, Berserkers don't just wear the bear parts to channel the animal's ferocity, they actually become animals themselves.

Argent says their human side doesn't last long because they are not tempered by the moon.

Appearance
The examples seen to date wear elaborate but crudely constructed armor made entirely of bone and skin. They wear bear skulls that cover their head and face.

Malia reports they smell like death.

Abilities
Berserkers are apparently super strong, able to tear the human body apart. In the only known case, related on the show, it took three hunters and hundreds of rounds of ammunition to kill one Berserker.

Real World Myth

 * EDITORS NOTE: What follows here is the barest overview of Norse folklore. It is not, nor is it meant to be, a full account of the Berserker story.

Berserkers were Norse warriors who were attributed with great strength and fury on the battlefield.

Historians differ on how they whipped themselves into a killing frenzy with some attributing their ferocity to drugs.

They wore the pelts of bears or wolves, both animals associated with Odin, and were said to absorb the abilities of the animal.

According to legend, neither fire nor iron could harm them.
