Az
Az is a Worker Drone infected with the Absolute Solver. Az works with the solver rather than fighting it. He left the worker drone colony/hideout after the solver suggested he takes care of the disassembly drones himself. Az lures the murder drones into a warehouse one by one where he kills them with his solver powers. Only one managed to escape, S (Linked below).
He is the brother of Spade (Linked below), though she currently doesn't have any story importance
