Bakugan Battle Brawlers: New Vestroia

Three years after Drago restored Vestroia, the Bakugan homeworld is conquered by the technologically advanced Vestals. The invaders force Bakugan back into ball form and treat the sentient creatures as entertainment. Drago escapes and returns to Earth to ask Dan for help, with Marucho following them back to occupied New Vestroia.

There they meet Mira, Ace, and Baron, Vestals who formed a resistance after learning the truth about the Bakugan. Together they challenge the Vexos, destroy the Dimension Controllers, and fight to free captured partners. Their rebellion soon grows into a struggle against King Zenoheld and weapons powerful enough to threaten every Bakugan.
