Plot
BRZRKR follows a mysterious, immortal warrior known only as B, a man who has lived for over 80,000 years, gifted—or perhaps cursed—with superhuman strength and speed, godlike regenerative abilities, and an uncontrollable urge to commit unspeakable acts of carnage and violence. In the present day, B works as a weapon for the U.S. government, undertaking black-ops missions too dangerous for normal soldiers. In exchange, they promise to help him unlock the secrets of his origin—and grant him the one thing he wants the most, the ability to finally die.
As B endures each brutal mission, his body quickly regenerates from horrific damage, but the many psychological scars of his unending violent life remain. Between operations for the US government, he's studied and counseled by Dr. Diana Ahuja, a government scientist who seeks to unravel the mystery of his biology and mind. Through her therapy sessions, they develop a strong connection, and B begins to recount his origins: he was born in prehistoric times to a human mother who prayed for a weapon to protect her nomadic tribe from surrounding oppressors, and the being of cosmic energy she prayed to, who impregnated her with B instead, granting them an undying living weapon with monstrous, uncontrollable rage.
From conception, B was very different from the average human. He spent only two months in his mother's womb before birth, his body developed, grew, and healed incredibly fast, and he killed violently without remorse making his people refer to him as Unute which means weapon or tool. This only reinforced and convinced his surrogate father to raise and train him as the tool of war they prayed for to protect their tribe from the relentlessness and savagery of the larger tribes and villages that surrounded them, sending him into battle where he slaughtered and dismembered enemies in increasingly gruesome ways. Eventually, his surrogate father's greed and desire for conquest eventually lead to the tragic demise of B's mother, and their entire tribe. After this, B wandered the Earth alone for centuries, fighting in countless wars, toppling empires, and inspiring a cult-like following of people who revered, manipulated, and followed him for ages, passing their ways and knowledge from one generation to the next. They sought to gain his abilities by all means, and have been trying, but failing for centuries. B was unable to procreate and lost loved ones who aged and died while he remained unchanged. The weight of his curse grew heavier with time, leading him to strongly desire a way to end his suffering and finally die.
In the present, the U.S. government, led by a high-ranking influential figure called Caldwell (revealed to be a member of the above-mentioned ancient cult), who seemed to understand the full extent of B's abilities and his importance to humanity's advancement over the ages, continued to use B as a living weapon, while attempting to replicate his DNA to build immortal super-soldiers. B Is fully aware of this, but remains indifferent to their intention as long as they could find a way to make him mortal. Together with Dr. Ahuja, B begins to uncover his true origin by confronting his repressed memories and emotions about his mother's death, and using a special device to harness his innate energy and connect with the cosmic being responsible for B's creation—his father. This brief connection reveals the location of his birth and an artifact his father gave to his mother before her death, one capable of permanently ridding B of his abilities and making him mortal. Through her close connection with B, Diana also connects with the cosmic entity, granting her abilities of her own, and a psychic connection to B.
B reveals the location of the artifact, heading there with the US military, Caldwell, and Diana. Utilizing their psychic connection to navigate B's memories, he and Diana find the artifact which he activates, summoning a massive bolt of energy from outer space to their location. The U.S. military taps this energy from orbit back to their secret base using a satellite. Caldwell's machinations come to light as he orchestrates events to transfer B's abilities to himself, and Diana activates her psychic connection to B, once again linking to the cosmic entity in an attempt to understand its intention. The climax unfolds with Caldwell, now imbued with B's former abilities. Now overcome with the urge to kill, he initiates an assault on the surrounding US military officials and B. Despite his newfound mortality, B confronts Caldwell, leading to a decisive battle. Diana's intervention proves crucial, as she utilizes her new powers to aid B in overcoming Caldwell's threat.
