The Chainsaw Majini is a Majini with an unusual adaption of the Plaga parasite, which has formed a perfect bond with the host, greatly increasing their strength and durability to damage. The Plaga causes them to harbour a great desire to kill all non-infected humans.
A Chainsaw Majini often appears as a black man wearing colored pants and a burlap sack on their head, which has a single hole exposing a single, bloodshot eye. Their weapon of choice is a blood-stained chainsaw, which they use to brutally kill their targets, but whose weight slows them down. Chunks of missing flesh appear in the hosts' torso, arms and hands.
