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". As the testing goes underway, with Marucho not doing so well, Mylene flies over, and in fury, Elfin and Marucho demand she and the Vexos return the stolen Bakugan. Angered at how cruel Mylene is to the Bakugan she already carries (by throwing them away like trash), Marucho and Elfin challenge her to a brawl. But Mylene soon begins to show her skill, and may end up winning Elfin as a new Bakugan! just when all of mylene's bakugan were no use, she unleshed a bakugan called a bakugan trap. Just when Mylene is about to seize Elfin, a hooded figure wielding Ventus Bakugan arrives and saves Marucho. Mylene states she's tired of losing to this hooded person and offers him to join the Vexos, but he leaves without saying a word and Mylene departs. Meanwhile, Marucho slowly awakens, despaired that Elfin was gone. But as it turned out, Elfin was merely off to find him some water, and then begins explaining how she couldn't let anything happen to her "goofy partner".

They plan to storm the Mother Palace and directly attack the Bakugan Termination System instead of protecting the Attribute Energies. But without a working Dimensional Transport system or the coordinates to the Mother Palace, it at first seems there would be no way out for the brawlers. But Dan quickly realizes that they can find the location of the Mother Palace by convincing Spectra. The brawlers are hesistant, as Spectra will not likely be cooperative, and they have no way to contact him. Mira adds that there would be no way Keith would trust any of them. Meanwhile, the Vexos discover that someone has opened a portal to Earth from an entirely different universe. As Spectra makes his way to Earth, Dan and Drago admit how similar they are in both brawling abilities and lifestyles. When Runo interrupts the two for dinner, Dan and Drago are suddenly transported to Spectra's ship now that the former Vexos had broken through to Earth. Once there, Dan learns that Spectra needs the Perfect Core from Drago in order to make Helios the ultimate bakugan. They strike a deal: if Spectra loses, he will take the Resistance to the Mother Palace, but if Spectra wins, Dan must willingly surrender the Perfect Core to Spectra. During the battle Spectra realizes that the only way Helios can defeat Drago is by using his own natural abilities and powerful will to survive and evolve. Eventually Spectra's doubt in himself and his previous methods to perfect Helios leads to his defeat. Dan wins the fight and Spectra agrees to the terms of the bet. Everyone except Runo, Julie and Billy are transported to Spectra's ship, since he states that he would only allow the brawlers and bakugan originally bestowed with the Bakugan Attribute Energies to go with him. As Gus prepares the ship for the transport, Spectra thanks Dan for enlightening him, and refers to him as 'my friend'.

Despite their power together, Zenoheld overpowers them with a last resort power transfer and takes the Pyrus attribute energy, making the BT system fully operational.

Helios chases after Drago, refusing to allow Drago throw away his life while Helios still has a score to settle with Drago. Drago and Helios agree to destroy the BT System themselves. However, their powers are not enough. So, in a last attempt, Drago lifts the BT System from the ground and lifts it up to the atmosphere. Just as the BT System detonates, Drago hears Wavern's voice telling him to not give up and that he cannot die yet. Drago, given new determination, absorbs the attribute energies from the BT System and evolves while easily destroying the BT System. He returns to New Vestroia, greeted happily by everyone excluding Spectra and Helios. Mira questions Spectra on their terms of partnership, but Spectra declares he works alone.

With the BT System destroyed and New Vestroia safe once more, the Bakugan are all moved back to New Vestroia from Marucho's house.

Baron, Mira and Ace decided to stay on Earth to train and head to Dan's house for dinner. However, Marucho calls them saying that a strange ghost data has appeared in Bakugan Interspace in the form of unknown Bakugan, which is later known to be digital clones of Neathian Bakugan. Everyone heads into Bakugan Interspace and meet four Bakugan that even Drago doesn't recognize! The Bakugan do not communicate, so Baron suggests battling with them. Marucho creates a digital copy of Baron so his challenger, Haos Aranaut, has a partner brawler. The battle does not go so well for Baron, and things get even worse when Aranaut uses Battlegear, the same thing which Helios had! Aranaut defeats Baron and Nemus and destroys the field of Bakugan Interspace. Everyone begins suspecting that Spectra may have sent the phantom data.

2x44 - Spectra's Last Stand

While wondering where the Bakugan from Bakugan Interspace came from, Mira has just about given up hope on waiting for Spectra. Then, Spectra and Helios telepathically contact Dan and Drago to challenge them to one final match to prove they are the best Bakugan team. Drago uses his new powers to locate Spectra and teleport them to his location. The match begins and Drago appears to have the upper hand, that is until Helios whips out his Twin Destructor Battle Gear, which gives Drago a hard time. In their final fight, Drago calls on the power of his friends and defeats Helios. Spectra and Helios admit defeat and admit that Dan and Drago are the best brawlers. Drago didn't care about being number 1. Spectra decides to take off his mask and "work with the best rather than against him." Spectra becomes Keith again and Mira hugs him out of joy, happy to have her brother back.

2x45 - Fusion Confusion

Keith has easily settled in as the newest member of the Resistance, with the exception of a jealous Ace. Due to failure, King Zenoheld abuses his son then Mylene tries to stand up for him. However, King Zenoheld rejects her until Hydron places the blame on Professor Clay. King Zenoheld agrees to pit the blame on Mira's dad. Professor Clay discovers the secrets of the DNA code as well as where the transmission originated from (from Neathia). Meanwhile, Marucho analyzes the same data, as well as the one Keith received anonymously and discovers they are identical. Keith then suggests to construct Battle Gear for Drago. Drago denies at first, feeling it would be wrong being part machine but Keith assures him that the Battle Gear will be constructed from Drago's own DNA. This along with the lasting Vexos threat, Drago agrees, but must undergo a battle to test the virtual prototype. They enter Bakugan Interspace and Keith volunteers to use Ventus Hawktor and Subterra Coredem to battle Dan and Drago as Spectra! When Dan equips the gear, Drago struggles with it as his body is rejecting the Battle Gear. However, Drago continues to push forward and wins the battle, but nearly passes out due to the amount of power needed to control JetKor. Fortunately, enough data was gathered to construct Battle Gear that would not harm Drago's body. Shun and the other brawlers hope that Keith finishes Drago's battle gear before King Zenoheld and the Vexos do. The episode ends with Professor Clay telling King Zenoheld he has begin making the ultimate weapon against the brawlers and King Zenoheld agrees with his research.

2x46 - Volt's Revolt

Keith, Marucho and Mira work on constructing Drago's Battle Gear. However, Keith notices that Mira is distracted. Mira admits that she wishes their father would come around like Keith did so they could be a family. Keith doubts he will but offers Mira Gus' robotic bee to contact him. She does so and asks him to change sides, but Dr. Clay angrily refuses. Meanwhile, King Zenoheld changes his plan to destroy any living thing that stands in his way. Volt finds this plan goes too far and leaves the Vexos to return home while Mylene wishes him luck. However, his home is no longer what it used to be. Volt meets some children who still see him as their hero despite the things he did as a member of the Vexos and even promises to teach them how to brawl. As the children leave, Prince Hydron appears and a battle quickly follows and Volt easily takes the victory. Hydron is furious and throws a grenade that opens a dimensional hole beneath Volt, sending him into a far dimension (possibly the Doom Dimension). As Volt sinks into the portal, he vows that Hydron will get what's coming to him for all the suffering he has caused innocent people. While JetKor has successfully been completed, King Zenoheld is glad to hear that Volt has been taken care of, he warns the others that they will suffer the same fate if they cross him.

2x47 - Payback

While the Resistance celebrate the success with Drago's Battle Gear, the Vexos begin to finish their plans for planetary domination. Lync remembers how nice Alice was to him and worries that she may be one of the casualties, so he copies the data for the Alternative System and heads to Moscow to give it to Alice. At first he hesitates, fearing that she may still be mad at him, but before he can make another move, Hydron appears and vows to destroy Lync. During the battle, Hydron implies that he wishes to leave the Vexos as well since he is mad that Lync has a choice to leave whereas he does not. Despite putting up a good fight, Lync is defeated and suffers the same fate as Volt. Before being completely dragged into the warp hole, Lync throws his glove with the chip inside in hopes that Alice will find it. After finishing cooking, Alice heads to find her grandfather and sees the results of Lync's battle with Hydron as well and finds his glove with the memory card. Alice gives the chip to her grandfather who insists they must show it to Dan and the others. When Keith asks how Alice found, she replied that Lync must have left it for her, but sadly adds that he may not be alive. Though the data suggests the Vexos Alternative System is incomplete, Keith states they will require the Bakugan DNA and Battle Gear data that they currently have, making them target for the Vexos once more.

2x48 - Mylene's Meltdown

King Zenoheld sends Mylene and Shadow Prove to collect the Brawlers' Battle Gear and Bakugan DNA Data so with the data the Alternative could be finished faster. Having followed Billy to Marucho's house in episode 37, Mylene and Shadow have prior knowledge to their hiding place. Once they arrive, they are ambushed by the Resistance, but Mylene takes Mira hostage! Keith quickly agrees to give them the data in exchange for Mira but instead he leads them to Bakugan Interspace. Despite Mira's attempts to change Mylene and Shadow's mind, a battle quickly follows between the four. Shadow is quickly and effortlessly defeated by Keith and MAC Spyder is destroyed in the process. Mira soon defeats Mylene and destroys Macubass. Keith offers Myelene a place in the Resistance but she bitterly rejects and throws one of Hydron's grenades. However, it results in a portal opening in Bakugan Interspace causing it to collapse, which means if it continues further causing the Interspace to shut down with the four of them still inside, they could be trapped there forever!

2x49 - An Heir To Spare

With Bakugan Interspace beginning to collapse on itself, Mira and Keith attempt to save Mylene and Shadow, despite her wishes to die rather than face dishonorment. Before she can change her mind, she and Shadow fall into the Death Ball's portal while Mira and Keith are extracted from Bakugan Interspace safely. Meanwhile, King Zenoheld learns of Mylene and Shadow's fall and blames their lose, as well as the Resistance obtaining the Alternative data, on his son Prince Hydron who he has tortured as a result. Later that night, Hydron has a dream in which Volt and Lync appear to him and tell him to take down his father and take the throne for himself. Though frightened by the dream, it motivates him to fight against his father. Meanwhile, Zenoheld's bakugan Farbros has been repaired and synchronized with the Alternative System. Hearing this, Hydron challenges his father and Prof. Clay transports them to the arena. Though Hydron quickly gains the upper hand, he is no match for Zenoheld's Assail Farbos. He loses and Zenoheld admits that they were never meant to be father and son and has Hydron imprisoned. While in his cell, Volt and Lync reappear telling him to overthrow Zenoheld. Hydron shouts he will defeat his father, while Gus Grav, presumed to have been killed in episode 39, listens from another cell.

2x50 - Ultimate Weapon

Hydron discovers that a fellow prisoner is none other than Gus Grav, who was presumed dead in episode 39. Meanwhile, Runo, Julie and Mira prepare a cake for Keith to officially celebrate his joining the Resistance. However, Keith's mind lingers elsewhere, something that Mira notices but Keith brushes off. Dan suggests that instead of waiting for Zenoheld's attack, they storm the palace. Keith, however, is too impatient and takes his ship to the Vest Palace on his own. A battle quickly ensues and Gus feels Spectra needs his help, so he tricks Hydron into battling so their bakugan can free them from their cells and Gus leaves to help Spectra while Hydron is left on his own. When Zenoheld nearly defeats Spectra, Gus arrives in the nick of time, shocking Spectra who is happy finding out that Gus had survived. The two then battle together, giving them the upper hand against Zenoheld. Partway through the battle, Prof. Clay informs Zenoheld that the Alternative System, a giant airship modeled after Farbros, is complete and targets Spectra and Helios for a test fire. The blast sends Spectra's ship flying and takes a huge chunk out of a small planetoid, with Spectra and Gus just barely escaping the impact. Farbros links with the Alternative System and King Zenoheld declares his quest for intergalactic domination to begin.

2x51 - All For One

With Keith having gone to the palace and having no way to find said palace, the Resistance are stuck. Luckily Alice and Dr. Michael arrive and use the teleportation signature left behind by Shadow and Mylene to back track to the palace. Meanwhile, Zenoheld continues his attack, forcing Spectra and Gus to retreat and come up with a plan of counter attack. The Resistance are saddened to hear that Tigrerra and Gorem do not wish to participate on the assault of the palace due to the fact that they know their limitations (which are lower than the rest of the team) and it would irresponsibly put Runo and Julie in danger. All of a sudden, Dr. Michael locks onto the palace's coordinates and the Resistance - minus Runo, Julie and Alice - head for the battle and arrive just in time to see Helios and Vulcan in trouble. However, the Alternative is far more powerful than any of them could have ever imagined (because despite the amount of damage they did, which was a pretty decent amount, the Alternative still repaired itself with Farbros). Keith realizes that because Prof. Clay built the Alternative, that he must be inside and asks Mira if she wants to confront him, which she does. Then, Keith uses a new battle gear, the Zukanator, on Helios, in hopes that it will even out the playing field. Keith blows a hole in the Alternative and he and Mira enter the machine.

2x52 - Final Fury

May 9, 2010

With the battle against the Alternative pressing on, Hydron shows up to lend a hand. Meanwhile, Prof. Clay receives a video transmisson from a faraway world just as Mira and Keith arrive to make one final appeal. Once the brawlers realize Mira and Keith are missing, they deduce that the siblings may have found a way inside, so Dan uses Jetkor to blast a hole in the Alternative while Gus and Marucho stay behind to guard the rear. Gus and Vulcan are nearly beaten when Hydron steps in and saves him. Shun, having suggested to find the Power Reactor of the Alternative AND having memorized the blueprints of the machine, leads the Resistance through the Alternative. However, they are all quickly caught in a trap against four mysterious bakugan, unrecognized by Drago. While Mira pleads with her father to abandon his evil plans with Zenoheld, Dan and the others destroy the four unknown Bakugan as well as the Power Reactor. As they make their escape, Prof. Clay saves Mira from falling debris, but is trapped on the ship and Hydron captures his father, forcing them both to "go down with the ship." Prof. Clay returns to this computer and finds that the video he received depicts Bakugan in war. The Resistance go their separate ways as Keith and Gus thank Dan for showing them the error of their ways. 3 weeks later, Marucho has completely repaired Bakugan Interspace and uses Akwimos to test it while Shun uses Hawktor and Dan sticks with Drago. Then, they are approached by a boy named Ren who asks them if they're the Brawlers.
