Star Scythe
From Unofficial Handbook of the Virtue Universe
Nictus, evil symbiotic Kheldians that feed off the life energy of Peacebringers and Warshades. They are dangerous threats in and of themselves, but attached to a host who is also dangerous leads to a new set of problems.
Most "Warshades" are reformed Nictus who now fight on the side of good, however some still keep their sinister intentions. Henry Jackson was one such man, privileged to be chosen as a host by a Kheldian but unaware that this being was pure darkness. Being a low level street thug to begin with, the powers given to him by the Nictus greatly enhanced his darkest traits. Together they are the "being" known as Star Scythe.
Jackson and the Kheldion's first action as a villain was the killing of the hero known as Piscis. This cemented Star Scythe as a significant threat to the hero community.
