The Rooters were the former secret Black Ops wing of the Null Void Plumbers and a splinter faction of the organization as a whole. They appeared as villains in Omniverse. Over time, they went rogue and split from the Plumbers, creating a rift. They made their main goal the elimination of Ben Tennyson, believing that he is not worthy of the Omnitrix, and that his presence might be a threat to the Universe.
