Tripod Theta is a Bakugan Trap that is gigantic in size and very threatening. He can suck up his challenger's energy with a special suction beam. He resembles a Sea God, with his trident staff that emits a triple laser beam attack. Three large concrete triangles protect his chest from harm.
It hasn't been seen since its introduction, possibly because Shun and Ingram fried it like Altair, Dryoid and Farbros as it was shown having smoke coming out of it after Mylene lost. It has Aquos, Ventus and Darkus abilities. If Shun did destroy it, it is ironic as he and Ingram are supposed to protect the Bakugan, though since it's created by the Vexos, it can be assumed that it pledged its loyalty to the Vexos and therefore was an enemy of the Brawlers. It was the first Trap to appear in the anime as well as the first to use attributes other than its own.

Power Merge: Transfers 100 Gs from the opponent to your Bakugan for every Bakugan you have on the field. (Standard Aquos Ability)
Octo Whip: Prevents the opponent from using an ability.
Tripod Theta is the Bakugan Trap that resembles the humanoid form the most.
All Bakugan that have "Tripod" in their names, have a Greek letter for the rest of their name (Alpha, Beta, Gamma, Delta etc.). For example: Tripod Theta, Tripod Epsilon.
