It is used mainly for storing and activating Ability Cards, showing G-Power, showing the current brawlers in a battle, and the brawlers' life force gauge. Some Gauntlets have also been shown to launch Bakugan and Gate Cards, and form energy blades for physical battles. They are also capable of stopping time around them.
The brawl will be started when all the battlers shout "Gauntlet Power Strike!" ("Gantoretto Chiyaji-on!" / "Gauntlet Charge-on!" in Japanese), after which, the center of the Gauntlet will flash and the brawl can begin. The device is operated by pressing a button on the tip, and then the compartment that cards go into will open. When the command "scan Bakugan data" is given, an area comes out, then the Bakugan is placed on it. Going through Dr. Michael's Dimension Gate requires a Gauntlet, although the Dimension Gate has been destroyed.
Gaunlets come in the color of the attribute the person uses. Examples are:
The Vexos Gauntlets look the same as other Gauntlets, with the exceptions of having black trim instead of white and three horns on the rear.
Gaunlets can also be used in actual hand-to-hand combat as well as Bakugan battles. To do this, the user must use a certain type of Ability Card which will cause the Gauntlet to project a wide thin beam of energy initially in the shape of a long knife, however the user may at will extend the energy blade. This particular ability debuted in the battle between Spectra Phantom and Cyborg Helios vs Dan Kuso and Neo Dragonoid and has now become a regularly used element in the show. It has also been used by Mylene Pharaoh who used it as a weapon to attack Mira Clay and Keith Clay and by Gus Grav to attack King Zenoheld.

- In Bakugan: Gundalian Invaders, they replaced it with the BakuMeter. Like the gauntlet, the BakuMeter can also open a time-freezing battlefield outside Bakugan Interspace with a push of a few buttons. So far, as of episode 13, only one person is needed to activate the field but at least two people to start the battle.
