Null Guardians are artificial creatures that are native to the Null Void.
Null Guardians have no eyes, legs or arms and instead they have tendrils coming from their lower body which they use as limbs. They look somewhat like Vulpimancers with tentacles hanging from the undersides and wings. They are capable of firing red lasers from their mouth and flying.
Galvans created the Null Void as a prison for their criminals, and created the Null Guardians to protect alien colonists from violent criminals, in a way the Null Guardians could be considered the prison guards or "guardian angels" of the Null Void. Null Guardians can be used to ride and can be easily tamed as shown by Vilgax and Kevin 11.
- The pop-up version of "Back With a Vengeance" declared that their species was named "Nullvoiders" and that they were the only indigenous lifeforms in the Null Void. But this has been retconned in Alien Force.
