Bakugan Battle Brawlers: New Vestroia (ニューヴェストロイア Nyū Vesutoroia) is the second season of the anime series Bakugan Battle Brawlers. It introduced a new battle system, including Bakugan Traps. This season contains 52 episodes, and was later followed by Bakugan: Gundalian Invaders.
Following the short return of peace on New Vestroia, calamity strikes them again. An alien race known as the Vestals have invaded and conquered New Vestroia, creating three Dimension Controllers to change the Bakugan them back into ball form and using the Bakugan as a form of entertainment. On top of that, five of the original Bakugan that helped restore order to New Vestroia have been captured, and Drago is now being targeted. With the help of Dan, Marucho, Shun, and the Bakugan Battle Brawlers Resistance—a group of Vestals who have discovered that Bakugan are sentient and are fighting for their freedom—Drago believes he will have enough power to not only free New Vestroia, but his friends as well.

New Battle System
(Note: this system has been used in seasons 3 - 4 as well)
- This battle system has a Life Gauge with 500 life points. It will decrease when your Bakugan loses battles (e.g. damage is 350 Gs, 500-350=150). When a players Life Gauge hits zero, that said player loses.
- In Tag Battles, players with zero life points cannot participate anymore.
- Unlike the original version, defeated Bakugan can be returned to battle in the next round.
- Only one Gate Card is set at a time, or not at all. There is no limit to how many Bakugan can stand on one card.
- If the winning Bakugan's G-Power is 500 or more than the losing Bakugan, that said Bakugan will go to the winner. There have been times this rule wasn't enforced, however.
- You're allowed as many abilities as you want. The general rule is that each card can only used once per round, though there have been some exceptions.
- The Brawlers need a Gauntlet to start each battle. The phrase to begin is: "Gauntlet, Power Strike!"

- Bakugan Battle Brawlers: New Vestroia DVDs (Original Japanese)
There are a total of 52 episodes in New Vestroia; although there were originally only going to be 26 episodes, the series was extended by Teletoon due to the high ratings it received on Canadian television.
- Very rarely, Japanese anime first airs in another country before being broadcast in its original country. New Vestroia is one of those rare occurrences because the first season was a flop in Japan. Teletoon aired it first in Canada to test its popularity abroad. After seeing how successful it was worldwide, even meriting a series extension, the Bakugan anime was given another chance in Japan. By the time Japan aired the first episode, Canada had already reached the forty-second episode a few days before that.
- This is the only season that has both main villains use a Pyrus Attributed Bakugan rather than the Darkus Attribute, like in the other seasons.
- This is also is the only season where the last member to join the six main brawlers is their Ventus brawler instead of their Darkus brawler.
- This season has a particular focus on the familial ties with the Vexos, between the Clay family (Mira, Spectra/Keith, and their father) and Zenoheld and Hydron. Mira's relationship with Spectra is an important part of her character, while Hydron's relationship with his father is a large part of the second arc.
