The Ultimate Annihilator

The Ultimate Annihilator

superweapon invented by former Emperor Xeno. It was a massive weapon capable of erasing things from existence and wiping out entire galaxies.


No one knows how Xeno created the U.A., but it is assumed that he used dark magic of sorts or simply studied the matter in the universe and how to destroy it.


The Ultimate Annihilator was destroyed when it self-destructed. This resulted in Emperor Xeno being erased from existence except for his soul which was contained in a jar.
