General Information
Species Human
First Appearance Ben 10-Generator Rex: Heroes United

Rex's Universe is an alternate universe where the series Generator Rex takes place. This universe is visited by Ben in the special Ben 10/Generator Rex: Heroes United.


According to Rex Salazar, the "Nanite Event" spread nanites across the world, and nanites are present in nearly every living being. When a person, animal, or plant's nanites spontaneously activate, the victim is mutated into a being known as an "exponentially variegated organism," or E.V.O. for short, becoming monstrous and typically losing any sanity and going on a violent rampage.

As seen in the special, the EVO threat is controlled by an organization known as Providence. EVOs, Providence, and other places like the Bug Jar are present here and not the universe of Ben. In this universe, alien contact has not been established and the idea of aliens is seen by at least Rex as something ridiculous.

This is another universe, not an alternate timeline, as there are no counterparts of Ben or his friends in this universe, as told in McDuffie Forums.
