Bakugan Battle Gear was launched along with the third season of Bakugan Battle Brawlers, Bakugan: Gundalian Invaders
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 mainas 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.
