The Triple Node is one of the most powerful abilities in Bakugan Battle Brawlers.
In Bakugan Battle Brawlers, the Brawlers have used the Triple Node. It can be used so the three allied Bakugan gain 200 Gs each. The Triple Node can be used for Pyrus, Aquos, and Haos or Subterra, Ventus, and Darkus. Chan Lee, Julio, and Klaus (E22); and later Nene, Akira and Shuji (E25) used it against Delta Dragonoid but lost.
In Bakugan: New Vestroia Dan Kuso and Spectra Phantom have used a Triple Node-like abilities when they form the Ultimate Formation to combine respectively Cyborg Helios into Maxus Helios & Neo Dragonoid into Maxus Dragonoid (Ep: 24-26) activating the ability card Parariddle Fire (Maxus Helios) and Vanishing Fire (Maxus Dragonoid). Also Helios MK2 can utilize the same ability when in ultimate formation.
In the first video game, they are available as Blue Ability Cards, with the three Attributes of Bakugan just needs to be with the brawler in the battle, whether in his hand, in the used pile, or on the field. They give 400 Gs to one Bakugan.
