Bakugan Battle Brawlers: New Vestroia

After three whole years, the peace of New Vestroia does not last long. An alien race called the Vestals (led by their King Zenoheld) invade and colonize New Vestroia, turning the Bakugan back into ball form and making them their slaves for amusement, not knowing that Bakugan are intelligent creatures. One by one the six fighting Bakugan are captured leaving only Drago. Now being the last hope for New Vestroia, Drago is separated from the Perfect Core by the six legendary warriors, and heads to Earth to seek out his old best friend Dan Kuso, now fifteen years old.

After the battle with Lync and Volt, Dan, Drago, and Marucho go with Mira to the Resistance base. Along the way, Mira reveals that only a few people of the Vestals realize that the Bakugan are intelligent creatures, while the rest of the people have not been told. She reveals that after discovering this for herself, and becoming outraged with her father for participating in the capturing of the Bakugan, she ran off and created the Bakugan Brawlers Resistance, joining with people who thought the same as she did.

Now that Dan and Marucho are part of the Resistance, they gear up and get ready to fight back against the Vexos, first by heading for Alpha City and the Alpha dimension controller, one of the machines trapping Bakugan in their ball form, to take it down. To get themselves ready, Dan offers to train Baron, who gladly agrees and can't wait for the lessons to begin but is afraid of what will happen when Dan finds out that he was the one who lost Tigrerra to Spectra. But after Lync and Volt were defeated, Spectra Phantom sends out Mylene Pharoah and Shadow Prove to ensure that the Resistance is taken care of.

Seeing how desperately he needs a partner to help Dan and the Resistance, Marucho takes his gear and heads out, in search of a Bakugan to battle with. At the same time, Mylene also goes hunting for Bakugan, after throwing away three she claimed useless. In the morning, Marucho meets Aquos Elfin, a Bakugan who turned out to know and have what might be a crush on Preyas. She explains that after his capture, she had to watch over the forest and protect the Bakugan living there from any harm. When Marucho asks to be partners with her, she at first declines because she claims to be "waiting for the right partner". But when Marucho explains that he needs her to help free the Bakugan (as this was what Preyas would have wanted) she says that if he passes her test, she will at least think about a "temporary partnership".

With the Vexos losing one by one, Gus Grav calls them all together to explain that the Resistance has to be defeated. So Gus decides to take matters into his own hands and confront the Resistance, and bring pride back to the Vexos. Meanwhile, the Resistance makes a stop en route to Alpha City, where Mira gives Dan a Bakugan Trap called Coin Scorpion to help in his battles. Not much is known about the Trap Bakugan except that they are incapable or unwilling to communicate. Excited, Dan takes off to get in some training with Scorpion.

Prince Hydron is furious because he still needs Drago to complete his bakugan collection, so Gus challenges Dan to a battle in an effort to capture Drago. The Resistance is planning to attack Alpha City, but Mira wants to take a short detour to find her brother. During the ensuing argument, Ace seems and sounds like he is worried about Mira going somewhere that might be dangerous, which shows that he may have romantic feelings for her. In the midst of the argument, Dan sneaks away with Drago to fight Gus and manages to battle well until Spectra joins in and Dan starts to struggle in the fight. Out of nowhere, Shun comes to his rescue. Shun beats Gus and Dan beats Spectra when Drago displays a massive power surge due to Helios' taunts about Tigrerra. Seeing that huge amount of power, Spectra shows a hint of betrayal when he says that he won't let the magnificent Bakugan become a play thing, meaning that he won't give it to Prince Hydron if he captures it.

After Shun successfully leads the Resistance into Alpha City, Mira departs on her own mission: searching for her older brother, Keith whom she loves and cares about very much. She heads to her home to search for clues on her brother's computer but comes up with nothing. After her father, Professor Clay, arrives, she confronts him and he simply says that "her brother is no more." When she further questions him, he leaves for his lab while Mira follows. Meanwhile, Shun takes the others to check out the control spire and they learn that the battles that take place in the arena below the controller are synchronized with the controller's power. At the lab, Mira witnesses the birth of the first cybernetic Bakugan: Ventus Altair. As the boys make their way to her location, Mira is confronted by Lync, who is armed with Altair.

Ace and Shun team up in a Bakugan battle tournament in order to overload the dimension controller because it draws power from Bakugan battles. After Marucho is "purposely" disqualified in the singles round, he sneaks the others in. They almost get caught by some guards until Mira pretends to be a huge Vexos fan and they manage to slip away.

Shun and Ace have made it to the finals and they prepare to battle Lync and Volt. they were brawling with Altair and volt's new bakugan, Brontes. Meanwhile, Dan and the others head to the dimension controller but lose Marucho on the way. Things only get worse when they discover many other talking bakugan and then they are captured by guards who are marveled by the speaking Drago. Just then Marucho drops in and saves them.

As the Resistance heads to Beta city, there is a scene where on both sides Dan and Runo miss each other dearly so Runo decides to go to New Vestroia to help Dan in defeating the Vexos. After Kato flies her and Julie to Moscow to meet with Alice and her grandfather, Dr. Michael reveals that his transporter is not functioning properly and refuses to let Runo go. Later that night, Runo and Julie sneak into his lab and Julie prepares to send Runo off.

Dan, Runo, Mira and Baron make it to the human world but pick up some unwanted visitors in the form of Spectra, Gus, and Lync. Marucho manages to defeat Shadow and he, Shun and Ace decide to take out the Beta city controller to pass the time. Before Spectra takes his leave, he grabs Runo as a hostage and offers Dan an ultimatum: join the Vexos or risk Runo's safety. Dan, Julie, Baron and Mira split up and Dan and Julie run across Spectra and Runo. Mira chases after Gus to find Spectra and Baron fights Lync. Spectra reveals that he is actually against Prince Hydron's rule and wants to team up with Dan to take him down and in a show of good will, releases Runo.

While Mira and Baron help out at Runo's family's cafe, Ace, Shun and Marucho head to Beta City to shut down the controller, which has grown stronger due to Drago (and the Perfect Core's) absence. Hydron sends Mylene to deal with the resistance in Spectra's absence and states to himself that, when he returns, Spectra will find that the Vexos have a new leader. Later at night, Ace, Shun and Marucho hear the voices of Mira and Dan (respectively) and head out into the night, but it turns out that Shadow is the one making the fake voices. By the time Shun realizes it's a trap, Marucho and Ace fall for it.

With Ace and Marucho captured by the Vexos, Shun decides to head to Beta City alone to destroy the controller. On the way, he is ambushed by Shadow Prove, who is armed with Darkus Hydranoid. In the middle of the battle, Shun and Ingram realize that it is not the same Hydranoid they know, it is really mechanical bakugan Darkus Hades.

Spectra and Gus, stuck on Earth, stay in an abandoned factory. When Gus returns with "juice in boxes",(there's no such thing as juice boxes on Vestal) he finds that Spectra is gone. While Dan trains Baron, Spectra runs into a fortune teller who tells him that if he stays on the path he has chosen then he will meet his end, but Spectra does not listen to her. Spectra decides to take Drago by force, now being tired of waiting for Dan to join him. He sends one of Gus' hornets to challenge him and they meet in the arena where he last fought Masquerade. Mira, Baron and Runo worry about Dan being out on his own. In the first round Dan takes a major loss, but manages to strike back with Pyrus Scorpion.

Dan is upset about losing Drago but tries to move on and think of ways to get him back: starting with all-out intensive training. Meanwhile, on New Vestroia, Mylene wants to close to portal to keep Dan and the others on Earth, but Prince Hydron orders her not to, so as to allow Spectra and Gus time to return, which angers Mylene, who greatly enjoys her new power. Apollonir states that they must retrieve Drago as the Perfect Core is losing power and the other two dimension controllers are growing stronger. While training, Dan faints and develops a fever. He runs out into the park calling out to Drago, lamenting over how he lost Drago.

Dan, with the help of Apollonir, brawl against Drago, but Drago is not himself anymore. Spectra has turned him into a corrupted black dragon. Dan tries to reach out to his friend, but it seems that Drago is unable to listen. Spectra uses the power of many forbidden cards to access Drago's Perfect Core abilities, but it puts Drago under mounds of stress. The legendary warriors conclude that Drago should not have been able to access the Perfect Core's power and change attribute while in his new body, but the power of the forbidden cards allows him to do so. Things look bad for Apollonir, as Drago seems unstoppable with all of this infinitely limitless God-like power. Dan then notices that Drago is crying and that if he doesn't stop Spectra from giving Drago so much power, Drago could die.

The Resistance is ready to head back to New Vestroia and Dan wants to bring Runo, Julie and Alice along. But Mira suggests that they spend one last day for Dan to say goodbye to his parents. Alice uses her teleportation card and Lync convinces her to take him too, but he really just needs to meet up with Spectra and Gus. As Dan and the others meet Alice at the tower, Apollonir opens a portal to New Vestroia. However, they are ambushed by Spectra, Gus and Lync and to make matters worse, Mira betrays them and heads into the portal after explaining that Spectra is none other than her older brother.

As Dan and Baron safely make it back to New Vestroia, they find their base completely empty with no sign of Shun, Ace or Marucho anywhere. They discover that they are near Beta City and believe that Shun, Ace and Marucho have gone there to destroy the next dimension controller, so they decide to go to Beta to give the three backup. Meanwhile, as Spectra makes his return, the other Vexos are shocked to see that Mira is with him, saying that she has joined the Vexos. However, in her mind, she only wants to find out what Keith is really up to.

Mira is uncertain of her brother's intentions while in Gamma City. Meanwhile, Ace is unconvinced that Mira has betrayed them due to his feelings for her, but they all resolve to head to Gamma City for the final controller. That night, Spectra invites Mira to dinner where he asks her to join him because he needs her and cannot accomplish his goal without her. Mira is unsure and retires for the night. Later she contacts Spectra asking to battle him and let that decide her fate: if she loses, she will serve him but if she wins, he must go back to being her brother.

Mira and Spectra meet with Prince Hydron, who shows her his collection and later receives a message from his father, who is angered by the destruction of the other two controllers. Hydron then orders Mylene to divide and conquer the Resistance, since she has shown that they are weaker on their own and orders Lync to keep an eye on Spectra and make sure that his new mechanical bakugan is ready for battle. The Resistance arrives and Ace and Baron explain that the controller is underground and is the strongest of all bakugan.

With Mira returned, and the Resistance reunited, Dan and the others head for Prince Hydron's sky palace to free Skyress, Tigrerra, Preyas, Gorem, and Hydranoid from captivity. But before they can even get close enough, Hydron activates another dimension controller, causing the Bakugan to turn back into ball form. Quickly thinking, Shun grabs Mira and Marucho and grapples onto the top of a rising elevator and to safety. Down below, Dan, Baron, and Ace are saved just in time by their Bakugan. But before they can think of a way to get up to the palace, Spectra and Cyber Helios challenge them to a battle. As Dan and Drago struggle to fight back against the power Helios now possesses, Shun, Marucho, and Mira have managed to sneak into Hydron's throne room and discover the bronze statues of the five other Guardian Bakugan, just before meeting face to face with Prince Hydron himself.

As the battle between Maxus Drago and Maxus Helios rages on, Mylene interrupts Hydron in his collection room by dragging him off. She explains that they are leaving New Vestroia. Hydron refuses at first, being afraid to face his father due to his failure to successfully occupy New Vestroia, but agrees to Mylene's plan to label Spectra as a traitor.

As Dan and Spectra continue their battle, and the self destruct sequence begins counting down, the rest of the six fighting Bakugan are freed from their prisons. As Shun and Marucho are reunited with Skyress and Preyas, the Bakugan in Dan and Spectra's battle suddenly return to ball-like states, and the battle ends in a tie. But CyberHelios wants to continue fighting, even if the battle is over. Cyber Helios and Drago engage just as Ace and Baron, riding on Percival and Nemus, meet up with Shun, Marucho, Mira, and the rest of the six fighting bakugan. As Cyber Helios and Drago battle, Spectra draws a blade, and forces Dan to battle him one on one. Before either battle can reach a conclusion, the Vestal palace explodes, barely giving Dan and Drago any time to escape as Spectra and Cyber Helios retreat with Gus, Brontes, and Elico (who were thrown out of the escape craft by Mylene). Gus immediately informs Spectra that the others left New Vestroia to blame the occupation's failure entirely on Spectra's betrayal. Spectra merely states that he never really planned on returning to the Vestal home world anyway.
