Aza is a parasitic life form of the extraterrestrial race, Silicote. This parasite is capable of surviving without a host, though weak with strength depending on the host’s power. In its original form the parasite is a teal blob capable of entering a host through an open wound or cut. Upon taking over a host, the vessel’s consciousness remains but they are trapped in their own body. Over time, the vessel’s body changes in subtle ways, gaining white hair, startling blue eyes, and a long lifespan.
