Sub-Electron Amplifier
From Multiversal Omnipedia
The sub-electron amplifier, otherwise known as the stone, was a man-made red jewel capable of creating unlimited amounts of energy and power by increasing regular energy thousands of times beyond its normal potential. It was created by Dr. Debolt of Khan Industries, in order to power Shere Khan's businesses indefinitely. However, it was stolen by Don Karnage and the Air Pirates, and used as the power source for their destructive weapon, the Lightning Gun. The amplifier was destroyed along with the Lightning Gun when both were knocked into the sea by Baloo.
