Although similar groups have been found around the world, berserker generally refers to the small class of Nordic peoples who could be found preforming inhuman feats on the battlefield. When in combat a berserker would fight nude and/or completely unarmored, sometimes taking the skins of bears, wolves or other beasts to heighten his appearance. Uncontrollable rage is the signature of the berserker. To enter this rage many would have pre-battle ceremonies in which they would consume alcohol, and work themselves up into a violent, bloodlusting mood through dance and similar actions, and then often take psychoactive drugs to make them, in combination with the mighty rage, immune to pain and personal hurt. As a result, these fierce warriors would not back down when injured or against overwhelming odds, and be completely numb to pain and the killing that they were doing. This is a lethal combination, and makes the berserker a plausible candidate for creating the werewolf myth, let alone a terrifying addition to the ancient battlefields of Europe and Scandinavia.

It is known that these specific warriors known as berserkers were often intense followers of the god Odin and other members of the Aesir, and would engage in religious ceremonies invoking these forces to imbue them into an insane, unmatched frenzy before battle.
With a mighty swing of his rough axe, the blood-covered skyclad Berserker pounded through the lines and formations of living flesh and blood, screaming as a dozen men fell to his blade, unwavering in his savage assault when blades and arrows pierced his own skin.

A norse warrior who drank the pee of slaves (trells) after said slaves had eaten mushrooms. The physical exertion of battle would kill the warriors if the mushrooms hadn't been filtered first.
