Bakugan Battle Gear was launched along with the third season of Bakugan Battle Brawlers, Bakugan: Gundalian Invaders. Bakugan Battle Gear can be played together with ANY Bakugan, but it can only be attached to the new Gundalian Invaders Bakugan. Like a trap, a Battle Gear is played during battle. However, rather than changing attributes, they give a boost to G-power, usually between 50 and 270 Gs.

Bakugan Battle Gear comes with a Reference Card. These cards are blue, and they are not in any used or unused piles; they simply detail the Battle Gear's special abilities.

The Battle Gear has the same main attribute colors as normal Bakugan does, but their symbols are different. These symbols mean Gold, Silver and Copper (replaces the term Bronze). The colors correspond to the Gate Cards in the same colors. That is, a Gold Battle Gear is most useful on a Gold Gate Card, a Silver Battle Gear is most useful on a Silver Gate Card and a Copper Battle Gear is most useful on a Copper/Bronze Gate card.

To play your Battle Gear, simply open it on the Bakugan in battle and add the stated G-Power. In addition, pay attention to your Bakugans' attribute. If it matches either of the attributes on your Battle Gear Reference Card, then you get to use the ability stated there as well. OR, if your Battle Gear matches the color of the Gate Card you battle on, you can choose to use any of the Reference Card abilities.

A player is allowed to use two 'special pieces' in battle: 2 Battle Gears, 2 Traps, or 1 Battle Gear and 1 Trap.

In our last overview of Bakugan Battle Gear, there were 15 known Bakugan Battle Gear. But Battle Gear has appeared in every episode of Bakugan: Gundalian Invaders so far and we have now reached 37 known Bakugan Battle Gear.
