Video Games

Ben 10: Protector of Earth

Earth is the main setting of the game, with the Tennysons traveling all over the United States to battle enemies.

Ben 10: Ultimate Alien Cosmic Destruction

Earth is the main setting of this game too, being the location where the Potis Altiare was sent by the Galvan when it crashed on Earth many years ago.

Alternate Future

A possible future Earth was seen in Paradox, when Professor Paradox showed Ben and his team what will happen if the Trans-Dimensional Monster gets out of Los Soledad. This Earth appeared to be a desert wasteland. This future was prevented by Ben.

Ben 10-Generator Rex: Heroes United

A parallel version of Earth exists where E.V.O.s and the Providence exist and nearly every living being is infected by Nanites.
