Doomsday Door

"Do not open until Doomsday!"

- The Doomsday Door

The Doomsday Door is a huge living door that opens as a portal between both the Earth and the Nether-Regions only at the very moment of doomsday (known by many names as the apocalypse, day of reckoning, the end of the world), and it is one of the many known items in the Ghostbusters universe. It made its appearance in The REal Ghostbusters cartoon series.

The door itself is a corporeal entity manifested as a sentient doorway to the Netherworld. It is not to be opened until doomsday, the end of the world.

Description
Its face bears some resemblance to a bull, complete with nose ring and two curvy horns. It has two extra horns on the top of its head.

History
When the world was left ravaged, the poltergeist energy held within the Doomsday Door would be freed to reconstruct and replace the world at large. The Place of Lost Souls is located one mile from the door. The Doomsday Door was buried for ages and a warning was left behind and written in the ancient Sumerian language.

Somehow, it was left untouched for centuries until the 1980s. 10 miles in from a New York subway station, the door was rediscovered during a construction project. Although its main purpose is to open only on doomsday, it was opened early by a team of subway workers, who stumbled upon it saying its line, "Do not open until doomsday." The head worker, ignoring the warning, signaled to begin drilling and prompted the door to open prematurely. The released energy immediately began to change everything and cause a mass transmigration of ghosts.

Soon after, the Ghostbusters manage to close the door again by pulling back all that was set loose by it. They used the flow of energy inside the door to supercharge their Proton Packs, set them to Full Dispersion Mode with Wide Angle, and shot the streams through the Power Flow Core to pull in the energy and ghosts. Despite knowing it also lead to their demise, the Ghostbusters were able to barely escape as the door sealed itself.

Personality
The entity takes its purpose very seriously and gives fair warning not to disturb it but it takes pleasure in scaring humans who do not heed the warning. It is unknown if the door itself acts on its own or the will of the spirits who inhabit the Neither Regions.

Powers and Abilities
This door holds back the energy of the Netherworld till doomsday.
