Extractor

The Extractor is a device that appears in Sonic Lost World. It is a large machine created by Dr. Eggman that was designed to extract the energy of Earth. It was initially used by Eggman, until the Deadly Six took control of it and nearly destroyed the planet with it. However, Sonic managed to stop both the Deadly Six and Eggman from using the Extractor for their nefarious needs.

Description
The Extractor is a several stories tall cylinder-shaped machine with a funnel-like suction component on the bottom. It is located in Lava Mountain on the Lost Hex, where it is hanging over edge of the cliff, with the bottom pointing straight down to the surface of Earth. Attached to the Extractor is a pipeline that leads to several storage containers for the energy it harvest.

When activated, the Extractor sucks up the latent energy of the Earth itself and everything on it, such as plants, animals and the air, in the form of green particles. When the world's energy is then pulled into the Extractor, it is converted into a green liquid that can be stored. The energy the Extractor harvests is highly potent and can be used to power and supercharge machinery. It can also be consumed by organic creatures and robots alike, resulting in their strength, such as physical and innate abilities, being greatly increased. The more of the world's energy that is consumed by someone, the stronger he/she gets.

Because the world only have limited recourses of energy, if the Extractor drains too much of the world's energy, it will cause the landscape to lose its color and leaving everything completely white, and eventually even cause everything living to wither away and die. If the Extractor were to drain Earth completely of its energy, it will completely destroy the planet, leaving it empty and dead. Furthermore, the Extractor is unstable. When in use, the Extractor's levels will fluctuate and create an unstable reaction, which will result in the Extractor going into overload once it reaches full power, meaning that it cannot be shut down manually and that it will continue to drain the Earth of its energy until the planet is sucked dry.

History
In Sonic Lost World, the Extractor was built by Dr. Eggman as a part of one of his schemes for world domination, where he planned to use the energy he harvested from the Extractor to conquer the world. Because of the machine's instability, however, when Eggman tried to use the Extractor to get some of the world's energy, he could only borrow a limited amount before he had to shut the Extractor down to prevent it from going into overload and destroy the planet.

When the Deadly Six managed to break free from Eggman's control, the group began using the Extractor themselves, intending to use the energy that it extracted to make themselves stronger and as well let it destroy Earth in the process. Realizing that the Deadly Six was using the Extractor to destroy the world, Eggman formed an alliance with Sonic and Tails to stop it. The plan was then for Sonic to bring Eggman past the Deadly Six to the Extractor so that he could reprogram its shutdown sequence, since the off switch was no more and simply destroying the Extractor as Sonic planned would create a cataclysmic explosion that would incinerate everything within a hundred miles.

Following the Deadly Six's takeover of the device, the Extractor continued to drain the world of its energy, dealing a large amount of damage to the planet and its inhabitants. When Sonic and Eggman reached Lava Mountain, Eggman betrayed his alliance with Sonic by faking his death, before sneaking to the Extractor while Sonic kept the Deadly Six occupied, where he managed to shut it down and used some of the energy it had extracted to power his ultimate mech for his inevitable battle Sonic. After Sonic and Tails arrived at the Extractor and Sonic defeated Eggman in his mech, Tails reprogramed the Extractor to return the planet's energy, thus returning everything to normal, before shutting down the machine for good.
