Dark Essence (Alcohol)

Dark Essence (ダークエッセンス Dāku Essensu) is a deadly drink that was created by the Brotherhood of Nocturnes for the Dark Essence strategy.

History
Sometime during the Crystal Skulls strategy, in case the plan backfired, SkullMask hired TokolosheMask to help him create and spread out a drink known as "Dark Essence". TokolosheMask and SkullMask created it from the remaining elements of Shade, Nocturnium and other mysterious ingredients. Once it was done, it was meant to be shipped over to the Shadowland Cave, but unfortunately TokolosheMask, MirrorMask and MuscaMask got lost and ended up at Kenya. After getting past Lake Victoria, sea monsters, bad weather and other various sea storms (of note MirrorMask left early and MuscaMask left before they made it out of Kenya), TokolosheMask soon finally arrived at the Shadowland Cave in mid November. The first ship of it began in Colombia, where members of a cartel were the first ones to be tested on.

Needless to say, it was very successful.

Effects
Unlike Shade, which caused the consumer to become a psychotic xenophobe, Dark Essence transforms the consumer into a Nocturne as well, with them often transforming into the last animal they came in contact with. It has no effect on Nocturnes themselves and is safe for consumption for them.

Trivia

 * Originally it was Shade (in fact in it's early appearances it was either called that or "Monster Shade") before then it was given it's own identity and name.
 * It is similar to the Mutagen Ooze from TMNT.
