He uses rape as his weapon. The business' motto is “Righting wrongs through penetration”.

Clients call on The Rapeman to handle cases such as the revenge of a jilted lover, forming parental bonds through a traumatic crisis, making disruptive co-workers more docile and other things of that nature. When engaged in his night trade, The Rapeman wears a black leather ski mask shaped like the head of a penis but no trousers or underwear. In the middle of a rape, if the woman became unresponsive or appeared to be enjoying the violation, he would use a “special technique” such as “M69 Screwdriver” or “Infinite Loop” to apply more pain to the victim. He sometimes has regrets for the contracts he fulfills, but he always does the job.
