Stratus

The most basic type of the Homunculus artificial lifeform, created by Singularity through advanced application of nanomachine technology and capable of replacing any and all human body parts and organs. The Stratus type can also fuse together to form various other types of Homunculi. Possessed of no intelligence to speak of, they are incapable of acting autonomously and are controlled mentally by Singularity, and the ribbons of light that extend upwards from their bodies are bundles of of neural fibers that act as telepathic receivers. In addition to being several times more agile than the average human, they can also liquify their bodies and transform their arms and hands into various weapons.
