Volt, save me!
—Alto Brontes only words to call for Volt in Brontes' Betrayal

Alto Brontes (Japanese version: Joker Brontes (ジョーカー・ブロンテス, Jōkā Burontesu?)) is the evolution of Mega Brontes in the Bakugan Anime.


Alto Brontes evolved from Mega Brontes. He has become mean spirited and gains more energy from defeated Bakugan. He has an extra set of arms to battle multiple Bakugan at once. His strength has grown ten times stronger, but has made him slower. A bright white circle on his chest can freeze a charging Bakugan with a single blast.


Bakugan: New Vestroia

Alto Brontes appeared when Gus used the Chaos Ability X on Mega Brontes and he was forced to evolve. Mega Brontes evolved into Alto Brontes due to this forced evolution.[1]

Volt Luster and Gus Grav brawl because Volt wants Brontes back. He fought Boriates, Volt's new Bakugan. During the battle Gus taunts Volt by saying, "He screamed out your name, Volt." Volt loses to Gus, but Brontes is thrown away once again by Gus. He ends up somewhere in some sort of desert-like region of New Vestroia. Afterwards, he cries, "Volt, save me!", in the same place Dan Kuso and Baron Leltoy entered New Vestroia after Mira Fermin left. He and Volt were never reunited and his fate remains unknown.[2]

  • Brontes is the only Bakugan that Spectra and Gus evolved that lost his own will (he fought against evolving with Chaos Ability X).
  • Alto Brontes was the only non-Trap Bakugan from the second half of New Vestroia to be released as a toy in North America.
  • Alto Brontes was the first Bakugan to have ridges sticking out of his ball form to the extent that he was nearly impossible to roll. As such, every future Bakugan to have ridges that prevented them from rolling was said by fans to suffer from "Alto Brontes Disease."
  • His scythe in the anime has an uncanny appearance to Reaper's scythe in the first anime, except his is Haos colored and Reaper's is Darkus.
  • His Bakugan form looks almost exactly like Mega Brontes, but with two extra arms.
