The Null Void Projector is a gun like weapon, it can project a circular portal which acts as a gateway to the Null Void dimension. It is unknown who originally built it but it was utilized by The Plumbers to put aliens and supposedly other creatures into the Null Void dimension as a prison. It is also located near the Shadow Realm, which is a system of planets that the species Chimera Sui Generis is from. Max Tennyson uses the Null Void Projector as an explosive to destroy everything in the area by removing the focusing lens. The null void projector apparently comes in many models as there is the "normal" null void projector which has a blue focusing lens which projects a portal for 2-way travel, the one used by Max in Alien Force is the Null Void Warp Projector which creates a ray of red light that does not allow 2-way travel and therefore is probably the best for the Plumbers as it cannot make more trouble for them by unleashing more aliens, the one used by Helen and Manny under the name of the Eradi-Cannon is apparently the first model as instead of being a gun-like weapon it is a stationary portal which needs help, such as that from Energy Nooses, to be effective. Another downside to the Null Void Projector MK1 is that it takes a while to recharge.
