BRZRKR, the comic book series from BOOM! Studios, co-written by Keanu Reeves, follows the man known only as B. He is half-mortal and half-God, cursed to a never-ending life of violence. After wandering the world for centuries, the Berzerker finds some sort of refuge in working for the U.S. government to fight in battles that are too dangerous for anyone else. In exchange, he is promised the one thing he desires the truth about his endless blood-soaked existence, and how to end it once and for all.
