Together with Volt, Brontes brawls for the Vexos to eliminate the Resistance. Brontes is a Bakugan who uses his Loony Magical ability to eliminate his rival's offenses. This mammoth monster can fly by using the propeller sticking out of his head. His gigantic legs allow him to move quickly and avoid enemy attacks, and his long arms stretch out to wrap around opponents during battle.
- Brontes has more arms than its two other evolutions combined: Mega Brontes has two, Alto Brontes has four, while this one has eight arms.
- Brontes, Nemus and Wilda weren't seen in the anime because they had evolved before the series began.
- His ball form is similar to that of Nemus.
- Brontes is named after one of the three younger cyclopses who forged Zeus' thunderbolt, Hades' helm of invisibility, and Poseidon's trident.
