E.N.G.I.S. (Ectosymbiotic Neuroactive Gestalt Integrated Suit) is a symbiote/goo creature resembling a blue muscular male shark humanoid, with markings on their chest (his left pec, to be precise). He has blue eyes and claws (toe and finger claws).
He has the ability to merge with an individual or more and augment their strength, speed, durability etc. The process requires the host to be absorbed by Engis and have their nervous systems meld together.
The process is extremely pleasurable, and the host has shared control of their enhanced body.
