The Mind Control Ray is powered by the Hyper-go-on energy that sustains the Wisps. A miniature version of it is attached to the Eggmobile and receives Hyper-go-on energy fom two containers on the back of the vehicle.
In Sonic Colors, Eggman kidnaps Wisps and drains the Hyper-go-on from them, turning them into Nega-Wisps. The project is carried out on such a large scale because he plans to mind-control the entire world. He demonstrates the power of the Mind Control Ray on a smaller scale by using it on Tails. The Mind Control Ray ultimately fails because, when Sonic battles Rotatatron (Globotron in the DS version) earlier in the game, the arm of the destroyed robot lodges itself in the ray. The hole in the machine that was created by the arm causes the Mind Control Ray to leak Hyper-go-on energy and explode, setting Tropical Resort on fire.
- Eggman cunningly disguised the Mind Control Ray as a space elevator, which is why Sonic never gave it a second thought.
- Despite its considerable size, the Mind Control Ray cannot be seen from everywhere in the park.
- The Mind Control Ray seems to drain Hyper-go-on fairly quickly, as seen in a cutscene, so Dr. Eggman's plan might not have worked for long, even if it had succeeded. This was, however, demonstrated with a prototype of the Mind Control Ray, and might have been fixed in Eggman's final product for the Mind Control Ray.
