Gundalian Showdown is the 36th episode of Bakugan: Gundalian Invaders. It aired on January 8, 2011.
Before the Brawlers return to Neathia, they have to defeat Gill, Airzel, Kazarina and Stoica. For most of the battle, they seem to be evenly matched. However, Gill reveals to the Brawlers, that Drago's DNA was responsible for helping Dharak break through the third shield. This angers Drago to the point where he defeats Krakix, Strikeflier and Lythirus. With that the Brawlers use this opportunity to escape to Neathia, but hesitate when they realize that Fabia is still locked in battle with Kazarina. She tells the rest of the Brawlers to go on without them, and fights Kazarina one on one. The Brawlers decide to travel back to Neathia with Airzel and Stoica following them. Meanwhile, the Castle Knights are fighting to keep the Gundalians at bay. Rubanoid ends up fighting against Contestir... under Linus. It is revealed in a flashback that Ren gave Rubanoid to Linus since he lost his partner and would be better suited to battle with a Pyrus brawler. Meanwhile, Fabia is struggling against Kazarina. Eventually, Kazarina gets impatient and orders some Bakugan Mobile Assault Vehicles to finish off Aranaut. But just before they get to defeat him, Mason and Nurzak return to help her out. Back on Neathia it looks like the Gundalians are going to win and Emperor Barodius commented that Dharak may not have to battle, but a few moments later the Brawlers and Dragonoid Colossus arrive and a fierce battle is about to begin.
