Cortex Vortex

https://en.wikipedia.org/wiki/Nadezhda_Troyan

The Cortex Vortex was an unstable and evil technology developed by Neo Cortex that scrambled the brains of rapids to make them more susceptible to indoctrination and manipulation. Cortex designed the technology using old soviet documents, and the device was initially created as a way to separate rapid drones and workers, but afterwards was used for all rapids. After the use of the technology, new soldiers were able to much more efficiently take over Wumpian settlements on Wumpa Island. The Vortex allowed rapids to be used for more complex operations usually delegated to corporation personnel, such as mining efforts and the smuggling of weapons. The technology had a side effect of making select rapids more rebellious instead of indoctrionational, and this led to certain rebellions forming in and around the Cortexian bases.

The device has since been banned in all nations.
