The FUNCTI0NDRONES are the most common soldiers in the FUNCTI0N. They are not as powerful as FUNCTI0NSQUARE, however they are still a force to be reckoned with. They have no free will, and are mostly controlled by a Xarothi, though the most elite are controlled by FUNCTI0NSQUARE.
They are humanoid, yet strangely lifeless. This was most likely intentional by the FUNCTI0N so that they would be mistaken for a less powerful soldier, as they have far beyond the capabillity to make them look exactly like a living thing.
