Roboticizer (Sonic Underground)

The Roboticizer is an object that appears in Sonic Underground. It is a device utilized by Dr. Robotnik and his empire to create robotic slaves from the citizens of Mobius via the process of roboticization.

History
The origin of the Roboticizer is unknown, although it is implied to have been invented by Dr. Robotnik. Following his successful takeover of Mobius, Dr. Robotnik, used the Roboticizer to transform the majority of the lower-class citizens into mindless robotic slaves loyal only to him.

Over the next many year, Robotnik would use the Roboticizer to punish any Freedom Fighter he could catch (and threaten his lackeys).
