The Void (place)

The Void is a dimension (and possibly a sentient being) where characters and objects from Elmore are erased from the world due to being a mistake. It made its first appearance in "The Void."

Overview
Over the course of the world's history, whenever a person, object, invention, game, fashion style or other miscellany that was considered a mistake to the world came into existence, it would be removed and erased from the real world and ends up in the Void. Sometimes when a person is sent to the Void, they seem to be frozen in time like a paused video, but one can break them out of it just by touch. The Void has TV static as its background or outer space, and the laws of physics are warped in the Void so that there is less gravity and the direction of gravity's pull twists and varies all around the place. The mistakes sent to the Void are left hovering or floating all around it, unless they're standing on a floating platform.

Once a mistake is sent to the Void, all evidence that they ever existed is removed from the world - everyone's memory of the mistake is erased (unless a person wears a tinfoil hat), the mistake's image will all but vanish from any photos and pictures containing them, and where anything that belonged to the mistake (such as their school locker or their house) was located, the world will just fold up over them to hide and get rid of them. When the world folds up over evidence of a mistake's existence this way, it is possible for one to force the fold wide open to form a portal between the Void and the world. This portal will suck up anything that is near it, and it works both ways, but it will begin to shrink over time and eventually close back up to stop the mistakes in the Void from getting back into the world.

Things and people sucked into the Void

 * Molly (formerly) - Erased and sent into the Void because of her boring and uninteresting personality. She was rescued by Gumball, Darwin and Mr. Small, and brought her back to the world of Elmore.
 * Rob (formerly, twice) - Erased and sent for unknown reasons, though his lack of a purpose in life or status as a very minor character may be the reason. He escaped back to the world by grabbing onto Mr. Small's van. He becomes disfigured as a result. He returns there in "The Rerun" when Gumball ejects him there using the Universal Controller
 * Gumball (formerly, three times) - Entered the Void through a portal to find and rescue Molly, then escaped back to the world. He returned to the Void again in "The Disaster" after Rob threw the Universal Controller into a portal which leads there. In "The Rerun" he entered the void to find and rescue Rob after sending him there, before he disappears completely out of existence.
 * Darwin (formerly) - Entered the Void through a portal to find and rescue Molly, then escaped back to the world.
 * Mr. Small (formerly) - Entered the Void through a portal to find and rescue Molly, then escaped back to the world.

Trivia

 * The mistakes contained in the Void include allusions to Darwin's original CGI design, a scrapped version of The Wattersons' house, and several models from How to Ratatwang Your Panda.
 * The Void made a brief cameo at the end of "The Oracle."
 * The Void is similar to DC Comics' Limbo, a dimension inhabited by old characters seemingly abandoned or forgotten by their publishers. And like this episode, any character that's returned to regular continuity forget ever being in Limbo.
 * In "The Void," "The Nobody," and "The Disaster," the portal sealing is a a reference to a curtain disguised as a neighborhood.
 * In the ending of "The Oracle," Banana Barbara painted the Wattersons running inside the Void, foreshadowing an event in a future episode.
