What compels a man to slice off his own penis, leg, nipple, and ear…and then turn that compulsion into a business of butchering others who claimed to want the same fate? For Marius Gustavson, a Norwegian man in London, it began with self-castration. From there, his obsession metastasized into a full-blown operation whereby he performed extreme body modifications on dozens of vulnerable men. Marius filmed the mutilations and streamed them on a pay-per-view website, where he also sold severed genitalia to paying customers. His hunting ground was the “nullo” community, composed of individuals seeking genital removal as a radical form of body modification.

Many struggled with Body Integrity Identity Disorder (BIID) and turned to Gustavson for help. Instead, they got mutilation, exploitation, and a predator who feasted on their vulnerability — sometimes literally - as Gustavson went on to cannibalize some of the very testicles he cut off. This case is almost too gruesome to believe. But, it isn’t just about mutilation: it’s about control, sadism, consent twisted into theater, and the terrifying lengths people will go to reshape themselves when the wrong hands hold the scalpel.
