PowerSap Device

The PowerSap device was a highly effective machine created and utilized by A.S.T.I.A.

Origin
Originally, the machine was merely a concept among A.S.T.I.A. to further level the playing field but the dream was fully realized by a group of scientists hired and funded by A.S.T.I.A. to create such a device.

The prototype was large and bulky and wasn't very efficient but over the course of a year became much smaller and much more effective.

Soon they were able to make gun-like versions of the device although it was extremely expensive and used rarely.

Usage
The PowerSap device was used to literally "sap" superhuman's powers. The machine would then convert the energy into usable energy for either itself, the H.Q., or the city. After the machine had sapped all possible energy from the superhuman it would automatically disengage the body (as the superhuman often died from the intense process as it was often incredibly painful).

Loss of Construction Blue-Prints
During the final infamous battle Volt, while literally destroying the A.S.T.I.A. H.Q. wall by wall discovered the notes, blueprints, and early prototypes of the machine and destroyed it all. He then destroyed the current versions of the machine.

All remaining evidence of how the device was built was destroyed once the H.Q. burned to the ground.
