Plumber Badge

A Plumber's Badge is a device used by the Plumbers and sometimes given to their children so they are not thought as alien invaders and captured by other plumbers by mistake. Introduced in Ben 10 Returns: Part 2, they serves as communicators and can generate a signature allowing them to locate their owners. Its "face" is the galactic peace symbol.

In season 1 of Ben 10: Alien Force, Kevin took Magister Labrid's Plumber's badge after he died. It was then used by them to find allies against the Highbreed, allowing them to locate Plumber's kids like Alan Albright and Michael Morningstar. Kevin's badge was taken from him by Magister Prior Gilhil in Darkstar Rising, but at the end of the same episode, he eventually named the three of them honorary plumbers, giving Kevin and Gwen their own badges.

The Omnitrix is mentioned to act as a Plumber's badge, explaining why Ben doesn't have or need one. This is the reason why the omnitrix takes the form of a Plumbers' badge when in alien form. The Ultimatrix, while still functioning like a Plumbers' badge, is not recognized as one. Because of this, Ben now has his own Plumbers' badge for identification and communicating with other Plumbers.

Description
A Plumber's badge looks like a circular, disk-like object marked with a green and black symbol. The green part is shaped like an hourglass. This symbol is actually the intergalactic symbol of peace, and was used too by Azmuth on the Omnitrix and Ultimatrix. When in use it glows and is manipulated by tapping different parts. The badge can be used on Ben's or Kevin's car. Some DNAliens have them and Agreggor has one, too, which would mean they were most likely stolen. Azmuth uses the badges symbol to show the Omnitrix and the Ultimatrix as devices meant for peaceful purposes to help other aliens to understand each other.
