|First appearance||Spectra Rises|
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 Battle Brawlers: New Vestroia
Mega Brontes was forcefully evolved into Alto Brontes when Gus used Chaos Ability X on him. Volt Luster, after finding out Gus has him, brawls Gus to get Brontes back, as Mylene Farrow had thrown Brontes and Elico out in favor of Mechanical Bakugan without Volt's approval. During the battle Gus taunts Volt by saying, "He screamed out your name, Volt." Volt loses to Gus and fails to reclaim Brontes, only for Gus to throw him away once again. He ends up somewhere in a desert-like region of New Vestroia, the same place where Dan Kuso and Baron Leltoy entered after Mira betrayed them. He and Volt were never reunited, as Hydron disposed of Volt for leaving the Vexos, and Brontes' ultimate fate remains unknown.

- 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, which made his physical toy nearly impossible to roll. Among Bakugan fans, such Bakugan whose ball forms had features preventing them from properly rolling were said to suffer from "Alto Brontes Disease", a term coined by YouTuber Kohdok.
- 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.
