Extractor

The Extractor is a device created by Doctor Eggman in Sonic Lost World. Located in Lava Mountain, the Extractor is meant to extract the energy of Lost Hex, hence the name.

Description
In Sonic Lost World, the Extractor is built by Doctor Eggman in one of his schemes as a means of conquering the world. The device, however, is unstable, and Eggman is forced to turn it off in order to avoid locking it into overload and destroying the world. But when the Deadly Six betray the doctor, they turn on the Extractor once more, and use the planet's energy to make themselves stronger. This continues until Sonic and Eggman reach Lava Mountain, when Eggman manages to turn off the machine and use some of the energy it extracted for his own evil purposes. Once Eggman and the Deadly Six are defeated, Tails returns the planet's energy and shuts down the machine for good.
