This is the alien life form that forms members of my fursona's race, Amagasite parasites latch onto a host as a base form and then control the host to add more to it's base form until it's absorbed 3 other life forms. Example my sona is made from a base form of a human, then a fennec, a white tail deer, and finally a lizard are added. The result always has a green and white pattern when finished despite the colors of the originals due to the colors of the parasite. the final resulting host will keep this parasite in their "center" in humanoids like my sona it's in the center of the chest and the parasite acts as a shape shifting regulator as an amagasite host's body is fluid in nature allowing for limited shape shifting and body manipulation on the molecular level. While it can be difficult in cases where a rogue amagasite needs to be taken out one would need only to destroy the parasite within their center and destabilize the host's cellular structure causing them to melt and die. Kinda grim but that is the one major weakness of this species as I don't really have any other weaknesses planned.
