Ben 10-Generator Rex: Heroes United

Ben 10-Generator Rex: Heroes United is an extended episode of Generator Rex with a guest appearance of Ben 10. It is set to air this Black Friday.

Plot
The plot for the most part is unknown. However, special footage premiered in The San Diego Comic Con. In the clip, Rex investigates a park, detecting something strange and sees Ben setting foot there through a portal as Humungousaur. Confusing Ben for an E.V.O., Rex battles with him across the pond to the city In the battle, Ben (as Humungousaur) turns into Diamondhead. Rex mentions that he will not let Ben destroy the city and, surprised that Rex does not know his identity, Ben transforms back into a human. Then, it cuts to a new scene where Doctor Holiday mentions there is something in the Bug Jar and the duo must go investigate. They accidentally put on each other's jackets with Ben questioning why his jacket smells like bananas and Rex comments how his is too tight. Bobo retorts that if Rex and Ben are their only hope, they're hopeless. Eventually, Rex and Ben will team up to face a common threat that is not known at the moment.
