Pirke serves as a reaper for the species of Rathnuc, his species likely, a race of galactic space pirates that has been quarantined to this day. Despite appearing to have two heads, he is headless as is the Rathnuc species. Those heads may be masks. Pirke is mentally deranged, and a sadist too. He revels in making his work as a reaper as agonizing as possible, usually tearing his victim apart before reaping their souls. Alongside Maweth and Yama, he is a reaper of the 37th Ward.
