Berserk

Berserk is a long-running manga series written by Kentaro Miura in 1990 which is set in a medieval Europe-inspired fantasy world. The story centers around Guts, a mercenary with a very large sword and a dark past, Casca , his ill-fated lover and Griffith, Guts's former best friend, who betrayed him in order to become a powerful god-like demon.

The manga was adapted into a 25-episode anime series which covers Guts's origins with Griffith and Casca while they were members of a mercenary group called The Band of the Hawk. When Guts and Griffith's luck finally turns, the Band of the Hawk arc ends messily, and the series returns to the present day to show the deep-rooted effects of everything that happened in the previous arc.

The manga is a masterpiece in terms of storytelling and artwork with well-developed characters and an interesting fantasy setting. Think of it as a manga equivalent of "A Song of Ice and Fire".

"In this world, is the destiny of mankind controlled by some transcendental entity or law? Is it like the hand of God hovering above? At least it is true that man has no control, even over his own will."

Berserker 

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.

Dump Berserker 

A dump so fiery and ass engulfing that your sphincter literally lights on fire. The person enraged by the passion of unsavory anal singeing then takes any object close to him and runs through the neighborhood wielding it, killing or maiming anyone in his/her path. The objects usually range from domestic cats to live people.

The snowball fight was ruined by Archie's dad going Dump Berserker and hitting all of us with a grandfather clock as he ran through us in a blind rage.
