Billy Billions seeks help of Mazuma, Will Harangue, Kangaroo Kommando, and Captain Nemesis to form a team (AKA: The Vengers) to take down Ben, make him look bad in front of all of Bellwood, and claim the title as the protectors of Bellwood. As the Vengers 'rescue' people before Ben and in better fashion, while Harangue edits footage to make them look good. With Ben annoyed at no longer seeking help or getting respect for helping, he "quits" being a superhero. It turns out that while they try and keep up their "heroics", without Ben they keep trying to one up the other for the spotlight. As The Vengers fight over who gets the most fame, Ben and Rook plan to take them down as the villains continuously attack each other. After realizing they're better as a team of villains, they fight Ben and Rook on live TV where everyone sees them for who they really are. They lose and flee, with local authorities in pursuit.

Meet the Rooters, the Black Ops wing of the Plumbers from the Null Void. They're hybrid aliens, with unique abilities and when they head to the Plumbers' Base, they're looking for Kevin for his property-absorbing powers. Ben sneaks out to get Kevin, who claims to not know the Rooters, but after a run in with them Kevin bumps heads with their leader, Proctor Servantis, he begins to recollect hidden memories. By the time they reach Plumber HQ Kevin remembers that he, Helen Wheels, Pierce Wheels, Manny Armstrong and Alan Albright used to be Rooters and Kevin was responsible for their powers, as well as the other Rooters. He also discovers that Max never had a parter named Devin Levin and the Plumbers Helpers are not Plumbers children. After a fight with the Rooters, Kevin sneaks away to Argit Enterprises to reveal to Argit their hidden past.
