Plumber Badge

A Plumber Badge is a device used by the Plumbers (and sometimes given to their children so that they are not mistaken for alien invaders and arrested by other plumbers). Introduced in Ben 10 Returns: Part 2, they serve 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 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. The 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 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, in Ultimate Alien, Ben had his own Plumbers' Badge for identification and communicating with other Plumbers.

Appearance
A Plumber Badge looks like a circular, disk-like object marked with a green and black hourglass 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.

In Omniverse, Plumber Badges look more like a light gray circular disc shaped like a circular hourglass with a red dot in the middle of it. Like real-world badges, most appear attached to a wallet, but standalone versions have appeared.

Description
When in use, the Plumber Badge glows and is manipulated by tapping different parts. The badge can be used on Ben's and Kevin's Car. Some DNAliens have them and Aggregor has one, too, which would mean they were most likely stolen. Azmuth uses the badge's symbol to show the Omnitrix and the Ultimatrix as devices meant for peaceful purposes.
