ToxicMan.EXE

Originally a cleaning NetNavi made to disinfect any cyberspace his job carries him to, something strange happened ever since the rise of WWW. A cybercriminal organization that terrorizes the Net in MMBN (WWW is a canon thing, not mine). Those who have seen this navi claim that he is now repurposed to spread toxicity, poison, and viruses. What could be the reason for such a thing...? Was it by force or willingly?
