Plumber (BTR)

The Plumber (actual name unknown) is a mysterious superhero-type character in Ben 10: Revamped who, for some reason, showed up around the same time Ben found the Omnitrix.

The canon Plumbers will be in Revamped, but it is unknown if the Plumber is directly involved with them.

The Plumber wears what looks like a canon Plumber suit, with a special mask that completely covers his face.

Biography
Not much is known about him aside from the fact that he knows enough about the Omnitrix to remove it from Ben. Azmuth mentioned a "Plumber" before his escape pod crashed, implying that the Omnitrix was intended for him.

He first appeared "attacking" Ben, who fought him as Diamondhead. However, he took the Omnitrix and left. Later, Vilgax showed up and fought him, trying to take the Omnitrix, but Ben showed up and said that it was locked, and it was shown that the Plumber had been turned into a clone of Ben, like canon Albedo. He was forced to let Ben remove the Omnitrix and unlock it so that Vilgax could use it, but Ben switched it out with a fake Omnitrix that blew up when Vilgax tried to use it. Ultimately, Vilgax was thrown into space, and the Plumber let Ben keep the Omnitrix because he was better at using it. Ben and the Plumber then teamed up to find Azmuth.
