Plumbers' Academy

The Plumbers' Academy is an academy for Plumbers. It was first mentioned in the Ben 10: Alien Force episode, Above and Beyond when Helen, Manny , and Pierce were going to become "real" Plumbers. We will see the academy haved made an appearence in Ben 10 - Ultimate Alien in the episode, The Enemy of My Enemy. It was used as a place to protect Argit and the captain of the academy wasn't happy of putting cadets as they are rookies in the line of fire as they are not ready to deal with that kind of stuff and turning the academy into a war zone without asking him as the place is for learning and its not a prison nor a battle field.
