Bakugan Battle Brawlers - Season 4 Episode 15 Interspace Under Siege
8.30 25 minutes With Bakugan Interspace under heavy attack from Chaos Bakugan, the Brawlers quickly jump into action. Anubias gives his team all his Bakugan before meeting up with Sellon to observe. The Brawlers make a plan to lure all the Chaos Bakugan into a single area and then delete it, despite the massive damage it could cause to the system. The plan is successful, but Marucho is halted by a lingering Team Anubias. All of a sudden, a mystery figure enters and when the dust parts, it is none other than Spectra! Spectra easily wipes out all the Chaos Bakugan with Darkus Infinity Helios when all of a sudden Team Anubias and Team Sellon's Bakugan attack them, followed by another wave of Chaos Bakugan. Dan suddenly arrives, having felt the distress in New Vestroia, with Drago to help.
