Dan heads to a cafe in town where Julie works to meet with his new friend Jake, a young brawler who is new to the game. The duo make their way to Bakugan Interspace where they meet up with Marucho, who gives Jake Subterra Coredem. They eventually meet up with Ren and Shun, who is locked in battle with Shuji. With Shun quickly seizing victory, Ren is scheduled to battle Dan next. As the battle between Helix Dragonoid and Linehalt intensifies, Marucho is forced to shut down Bakugan Interspace and Dan is knocked out cold because of an explosion during the battle. Before coming to, Dan has a vision of Bakugan at war each other, something which everyone, except Ren, brushes off as a hallucination.|- class="vevent" style="text-align: center; background: none repeat scroll 0% 0% rgb(242, 242, 242);"| id="ep02"|02| class="summary" style="text-align: left;"|'''"[[Revelation]]"''' ("Battlefield")''"Senjō"'' (戦場)|April 10, 2011|May 30, 2010

Unable to identify Drago, Barodius orders that this Bakugan be brought to them before it joins their enemy. Back on Earth, Jake and Julie believe that what Dan saw was a dream, though he is still convinced that it was real. Just then, Marucho calls and everyone heads to Bakugan Interspace, where Ren confesses that he is a humanoid alien being from Gundalia looking for strong battlers to help fend of the invading Neathians. Though hesitant, the Brawlers accept and track down two moles identified by Ren, Sid Arkale and Lena Isis and a battle ensues. Though Sid and Lena gain the upperhand, Dan pulls through with JetKor and wins the battle. However, there may be more to Ren than meets the eye.|- class="vevent" style="text-align: center; background: none repeat scroll 0% 0% rgb(242, 242, 242);"| id="ep03"|03| class="summary" style="text-align: left;"|'''"[[The Visitor]]" '''("Encounter")''"Deai"'' (出会い)|April 17, 2011|June 6, 2010

Dan, having slept in, rushes to Bakugan Interspace and runs into Fabia, literally. Dan tells them about the girl and Ren suspects she may be a Neathian spy. Before they can track her, Fabia arrives and is shocked to find that Ren, a Gundalian, has gained their trust first! Now that Dan has sided with the Gundalians, Fabia claims they are her enemy and a battle ensues between her and Dan. Dan quickly takes the lead but falters when Fabia summons Haos Aranaut, the original Aranaut from which the clone Aranaut, Coredom, Hawktor and Akwimos originated, meaning Fabia sent the Phantom Data. Defeated, Fabia leaves and wonders what to do now that Dan has sided with the Gundalians. While the others congratulate Dan on his victory, Shun disappears to ask Fabia what her side of the story is.|- class="vevent" style="text-align: center; background: none repeat scroll 0% 0% rgb(242, 242, 242);"| id="ep04"|04| class="summary" style="text-align: left;"|"'''[[Brawler To Be]]'''" ("Touchdown")''"Tacchidaun"'' (タッチダウン)|April 24, 2011|June 13, 2010

When another mole, Mason Brown, is located, Dan challenges him to a battle, but Jake steps in and wants to prove himself. Due to his inexperience, Jake quickly loses and feels he has failed Dan in proving himself. The next day, Jake is still upset over his loss, so Julie, being a Subterra master, offers to help him discover his own battling style. Jake returns for a rematch with Mason while being greeted by a bitter crowd. With his newfound confidence, Jake easily defeats Mason. Before the Brawlers can pursue Mason, he teleports out of the stadium.

The puzzling part is that each brawler is eventually returned to BI. Meanwhile, Sid and Zenet find their recruiting hard when Marucho puts out an announcement to everyone not to battle Sid, Lena, Mason, Jesse and Zenet. In retaliation, Sid and Zenet challenge Dan and Ren to a battle. Ren is quickly taken out, leaving Dan to fend for himself. Being outnumbered, Dan loses but Sid allows him to keep Drago. After the battle, Gill of the Twelve Orders orders Sid to not engage the brawlers and to leave it to Ren, who states their plan is working perfectly.|- class="vevent" style="text-align: center; background: none repeat scroll 0% 0% rgb(242, 242, 242);"| id="ep06"|06| class="summary" style="text-align: left;"|'''"[[Exposed]]" '''("Suspicion")<br />''"Giwaku"'' (疑惑)|May 8, 2011|June 27, 2010

Dan heads to the new arena to challenge him but is stopped by Fabia, who claims that Jesse is not who he claims to be, and battles him instead. Ren insists that they do not cheer for either of them and they should just let their enemies destroy each other. Despite this, Dan, Jake and Marucho cheer for Fabia. Although she puts up a good fight, Fabia loses due to a bug in the field, causing her to cry over her loss. Shun explains that the only person who could plant an unlikely bug that caused Fabia's defeat was someone familiar with the BI System, someone like Ren. Ren denies everything while Jesse flees. Fabia and Shun expose Ren for lying about how Neathia attacked Gundalia, causing him to run away.

Meanwhile, Fabia tells everyone her side of the story: Neathia was attacked by Gundalia and, due to their Bakugan's inexperience in battle, they quickly lost to the Gundalian Bakugan. Fabia then sent out a distress message via the Phantom Data which lead her to BI on Earth. Shun discovers the battle going on between Marucho and Ren and when they arrive, Marucho defeats Ren. Ren attempts to get Marucho to switch sides, but he refuses to leave his friends.

Relieved, Fabia gives Shun, Marucho and Jake the real Hawktor, Akwimos and Coredem. Meanwhile, Ren leads the other Gundalians to kidnap two brawlers named Taylor and Casey. The two are taken back to Gundalia where they are brainwashed into fighting against the Neathians. Dan and the others confront Ren who sends Taylor and Casey to attack them. Dan and Shun battle Mason and Taylor while Marucho and Jake battle Sid and Casey. Fabia, however, sneaks off in hopes for finding Ren to discover his plans. After winning their respective battles and freeing Taylor and Casey from the Gundalians' control, they are all forced out of BI.

Ren reminds him of the story behind their loyalty to Barodius: there were many ancient Bakugan with Forbidden powers but they were sealed underground. Eventually their numbers dwindled to just Linehalt. Ren was the last descendant of the Protectors of the Dark Bakugan and was assigned to take care of Linehalt. Over the years, they bonded and dreamed of escaping their underground prison until Barodius recruited them to lead the invasion team to Earth. Meanwhile, Marucho and Fabia infiltrate Bakugan Interspace. Marucho tries to regain control while Fabia and an Avatar Marucho battle Lena and Zenet. The Avatar is quickly taken out as Ren discovers Marucho's invasion. Fabia is defeated and Zenet and Lena decided to take her back as a prisoner, something that will give them an edge against Neathia. However, Marucho arrives in time to get her out. Though their mission was unsuccessful, Marucho reveals he installed a back door to better access Bakugan Interspace without alerting Ren and his team.|- class="vevent" style="text-align: center; background: none repeat scroll 0% 0% rgb(242, 242, 242);"| id="ep11"|11| class="summary" style="text-align: left;"|'''"[[The Secret Package]]" '''("Messenger")<br />''"Messenjā"'' (メッセンジャー)|June 12, 2011|August 1, 2010

As security tightens for the brawlers, their attempt to bring kids out safely is getting more difficult. After Shun returns from saving more kids, he runs into Linus who is looking for Fabia. Though reluctant to trust him at first, they are attacked by Ren and Jesse and a battle ensues. Linus' partner Neo displays incredible power but the battle eventually goes to Jesse, who takes Neo as his victory prize. Linus is taken back to the others after being injured during the battle.

With Drago evolving once again, Dan easily takes a win. Meanwhile, Neo appears to Linus in his dream to bid his friend a final farewell, his mission now complete.

Nurzak plans to use Kazarina's attack on the emperor as his chance to sneak away to Neathia and give the brawlers the Switch Code, something that can supposedly control the Sacred Orb. Meanwhile, Gill informs Barodius of Nurzak and Kazarina's betrayal and heads to stop him before he leaves for Neathia. Kazarina arrives with her troops and reveals that she is actually working for Barodius as a triple agent! However, Barodius decides to deal with Nurzak via battle. When Sabator begins absorbing Dharak's power, it proves to be too much for him to handle. Barodius destroys Nurzak and Sabotaur and the entire building as well. The Brawlers, still waiting for Nurzak, conclude that they have either been stood up or something has happened to Nurzak. Back on Gundalia, Barodius thanks Kazarina for her services while Gill vows to take Kazarina down, still not trusting her.|- class="vevent" style="text-align: center; background: none repeat scroll 0% 0% rgb(242, 242, 242);"| id="ep22"|22| class="summary" style="text-align: left;"|'''"[[Mobile Assault]]"'''|August 7, 2011|October 2, 2010

While Kazarina experiments on more Bakugan, she sends Ren to collect more battlers from Bakugan Interspace while Gill sends Stoica with him. Stoica however, bails to do things his way leaving Ren on his own. Meanwhile, the Subterra Brawler Fabia defeated in episode 3, Koji, attempts to get in to have a battle, but is stopped by Julie, who tells him about the Gundalian-Neathian war while Stoica watches from afar. Koji leaves, believing Julie's story is too farfetched, and Stoica convinces him to head to Gundalia where he and other kids are brainwashed by Kazarina. With more kids attacking, Dan and Fabia split off from the others and encounter a Bakugan Mobile Assault Vehicle, a highly evolved Battle Gear, named Implanton. Fabia immediately recognizes Koji but is unable to get him to remember her. Fabia decides to use an Assault Vehicle designed for Drago and has it uploaded to his Bakumeter, and while it is downloading, she holds off Koji. The upload is complete and Dan easily defeats Koji with Drago's Assault Vehicle, but Koji is still under their influence. Dan vows to free all the kids from Gundalian control. Kazarina releases control and the kids are returned to Bakugan Interspace. Koji tells Julie about what happened and how he doesn't remember anything after meeting Stoica but he vaguely remembers Dan's voice.|- class="vevent" style="text-align: center; background: none repeat scroll 0% 0% rgb(242, 242, 242);"| id="ep23"|23| class="summary" style="text-align: left;"|'''"[[Sid Returns]]"'''|September 11, 2011|October 2, 2010

Armed with a Bakugan Mobile Assault Vehicle, Drago quickly tears through the Gundalian forces. Drago is suddenly ambushed by Ren and Linehalt but the two are too evenly matched. Dan begins asking why Ren fights for Barodius to which Ren reveals Barodius gave him freedom. Dan mentions that the emperor put him in darkness and that Ren must have been happy being friends with Marucho, even though if it was a ruse. Ren shouts at Dan saying that he is Gundalian and he knows nothing, but Dan replies that he is also a Brawler. Dan tries to get Ren to join them, but Ren refuses to forget those who have fallen at his hands (Sid, Lena, Jesse and Zenet). The fight continues but Rubanoid suddenly enters, being commanded by Sid.
