Joshua the killer

Requested by Modern noob[67036515568] it's Joshua the killer aged 20, Joshua the Killer is an Entity in the form of a 20-year-old male human, originating from an urban legend about a serial killer who is infected with a giant parasite and is controlled by it, and who kills people. His parasite has sprout out from his heart and is biting his head like a hood, and has infected almost his entire body, so the human-looking part is already a corpse. He is active in escaping and can easily kill ordinary people, including ordinary soldiers and police officers, but if you are a trained agent of the PPF, it will not be too difficult to subdue him[for if your oc is a trained agent of the PPF which idk what it means cus I just copied and pasted it]
