Bakugan Traps are a type of Bakugan that usually don't have G-Power, but there was rumors they were supposed to, instead they have Attributes. In the show, they are usually Mechanical. Bakugan Traps are shaped differently than normal Bakugan pieces. Each Trap has at least one attribute, or a second attribute symbol hidden inside. Unlike the normal pieces, they are only played during the battle stage, after the Gate Card has been flipped up. The Trap piece must have the same Attribute as the battling piece. The battling piece then has its attribute changed to one of the attributes hidden inside the Trap piece. For example, a Haos Dragonoid is played as the battling piece against a Ventus Falconeer. Once both pieces are standing on the Gate Card, the card is flipped and the player controlling the Dragonoid stands his/her Haos Zoack on the Gate Card. The Zoack has a Darkus attribute symbol hidden behind its arm, changing the Dragonoid to the Darkus attribute. Like regular battling pieces, many Traps also have their own Ability Cards, like Tripod Epsilon and Dynamo In the New Vestroia rules. You are allowed to play two support pieces, including Bakugan Traps.
