由BOOM!工作室出版的《狂戰士BRZRKR》是一部由基努李維(Keanu Reeves)與紐約時報暢銷作家馬特金特(Matt Kindt)共同創作的原創漫畫，圖像則由參與過多部漫威漫畫作品著名的羅恩加尼(Ron Garney)繪製。

　　故事圍繞在一位名為「B」的主角身上，他是花了萬年不斷磨練技巧的不死半神殺手。直到現代B成為美國政府的特工，渴望揭開自己存在背後的真相，並找出了結自己永恆壽命的方法。而B在漫畫中的外型就是參考基努李維本人所設計的，因此，當Netflix宣布將收購漫畫的翻拍版權，真人電影版當然由本人演繹。

＂The man known only as B. is half-mortal and half-God, cursed and compelled to violence...even at the sacrifice of his sanity. But after wandering the world for centuries, the Berzerker may have finally found a refuge working for the U.S. government to fight the battles too violent and too dangerous for anyone else. In exchange, B. will be granted the one thing he desires - the truth about his endless blood-soaked existenceand how to end it.＂--Provided by publisher.
