Dark Energy

Dark Energy also known as Ghoul Energy is energy that's given off of Ghoul Slugs and Dark Water, but is naturally found in the Deep Caverns.

Properties

• Source of life and power for creatures from the Deep Caverns and things that have been corrupted.
• Being surrounded by Dark Energy prevents regular Slugs from transforming at velocity.
• Overtime normal Slugs feel ill, and can die.
• Items powered by Ghoul Energy have a reddish glow as opposed to things powered by Slug Energy, which is blue.
• Exposure to Dark Energy can cause changes to a living being, such as the skin to turn ghostly white like Dr. Blakk in Back to Blakk, to be mutated into a monster like Dr. Blakk in Slugterra: Return of the Elementals, or gain immortality and other dark abilities like The Emperor as revealed in The Fall of the Eastern Champion.

Uses

• Powers Mecha Beasts that have been ghouled and makes them defective and explosive as seen in Mecha Mutiny.
  • Blakk Industries' equipment looks like they might be powered by Ghoul Energy, but they haven't shown any problems.
• Used to create and power Terraportals, so far only to the Deep Caverns.
• It can also be used to twist and corrupt slugs and mind-control other living things (slingers/humans, Ogres, etc), if ghouling them is impossible.
• Perform Dark Magic such as enhancing a Ghoul Slug, creating automatons and weapons, even draining life force from a living being.

Trivia

• Up until Slugterra: Ghoul from Beyond, it was believed that Dr. Blakk "created" Ghoul Slugs, therefore he "created" Ghoul Energy.
