Alpha is a villain in Ben 10-Generator Rex: Heroes United. He is an old creation of Caesar, Rex's Brother.

Ben 10-Generator Rex: Heroes United
He is a dangerous entity that can take over host bodies and control and absorb machines, including nanites. When it went rouge and developed self-awareness to attempt absorbing the Nanites that were imbued in the human population (thus killing the hosts in the process), he was deemed too dangerous to let it stay on Earth. Using a dimensional-equivalent to a Null Void Projector, Caesar banished Alpha from Earth where it wouldn't kill humanity. However, unknown to Caesar, the Alpha was sent to the Null Void where it possibly came into contact with an alien with the dimensional-equivalent of Nanites that it would use to return to Rex's world once more in pursuit of his "father".
