Syndicate Drone: A Pacifist Antagonist.

[Frank_Stein]

Add a new category of Side-Antagonists. For the annoying things that are still (mostly) harmless.

They make the floors wet and don't put up a sign

They turn off the securitrons

They steal all the candy in the vending machine 

They are the unseen terror of the station. The Wraith Drones

There we go, that's the direction to take there powers in. Annoyance

Give them dispenser for wetting and space lubing the floors
A syringe to inject food with stuff that makes you sick and puke
A N20 gas canister for creating clouds of sleep gas

Basically, a science gremlin. You don't know if they messed with your stuff because they're too sneaky to be seen, but you're gonna blame them for anything that went wrong.
