Null Void (Classic)

The Null Void is a different dimension created by the Galvans as a penal colony and also a prison. It is filled with what look like never ending rocks. There is also gravity. Null Guardians are the guards of this prison dimension.

The realm is normally accessed by a Null Void Projector. Max Tennyson is a known Null Void holder. He and his former partner, Phil, have owned one and trapped millions of aliens in it while in their Plumber years. If a projector is broken and someone tries to access it, it self destructs immediately, with the power of a hand grenade. It is possible to release aliens within the realm. Some places that lead to the realm are like Anur Phaeton.

Later in Alien Force it is discovered that settlers live there as well the descendants of criminals.

Fusion Fall
In the Game, players begin at the null void for basic training. There is a plumber training camp there along with Ben and the rustbucket3.

The Null Void background in the character selecter is a gitch for when a player moves up a level to the Zoo or Mt. Neverest it would stay like that untill the players move to sector V, after training.

Trivia

 * The Null Void seemed to a horrifying (an unpopular) place, for example: Kevin scared and horrified of going in there(or threaten to go there), Ben claiming that being in the Null Void is worse then prison, many aliens suffering in there, Argit hesitating to go there, Manny and Helen mistook a Null Void projector for an extinguisher, even Vilgax had a eye twitch by just mentioning it, calling it accursed.
 * The Null Void is similar to the Phantom Zone, an intergalactic prison in the Superman universe that keeps dangerous criminals, such as General Zod.Fusionfall_-_Null_Void.jpg
