Berserker

History
Berserkers were not born from Lycaon, instead they were born from an ancient ritual. This ritual included the binding of a bear skull and hide to the person and thus attaching the spirit of a bear to them.

Appearance
Berserkers are giant and very bulky. They always have some sort of bones adorning them and will always have a skull on their heads acting as a form of armor.

Diet
Berserkers are like bears in human form, which gives them a bears diet.

Super-Strength
Berserkers are easily the most physically powerful of the supernaturals being able to incapacitate any other supernatural in close proximity within half a minute.

Super-Human Durability
Berserkers have extremely high durability, the only way to permanently kill one being to seperate it's spirit and then destroying the corporeal form whereas just destroying the corporeal form would most likely leave the spirit alive and just seperating the spirit would leave the corporeal form alive.

Superior Senses
Berserkers have superb senses meaning they can track their "prey" very easily and even a teleporter like an Oni may not have a chance of escape.

Lack of Cleverness
While it is true that berserkers have consciousness it seems that many berserkers are impaired when it comes to their wit, cunning, and overall intelligence, although the original, Asmodai seemed to be an exception to this rule.

Moonlight Rings
Berserkers can be pacified by moonlight rings, if one was to have a moonlight ring forcefully put on the Berserker would fall into a deep sleep like state.
