Ultimate Weapon is the 50th episode of Bakugan: New Vestroia. It aired on May 8, 2010.


Hydron discovers that his fellow prisoner is none other than Gus, who was presumed dead in Avenging Spectra. Meanwhile, Runo, Julie and Mira prepare a cake for Keith to officially celebrate him joining the Resistance. However, Keith's mind lingers elsewhere, something that Mira notices, but he denies. Dan suggests that instead of waiting for King Zenoheld's attack, they should storm the palace. Keith however, is too impatient and takes his Vestal Destroyer to the Mother Palace on his own. A battle quickly ensues, and Gus flees from the jail when Spectra needs his help, by tricking Hydron into battling so their Bakugan can free them from their cells. Then, Gus leaves to help him and Helios, while Hydron is left on his own. King Zenoheld nearly defeats him, but luckily, Gus arrives in the nick of time, shocking Spectra who's happy finding out that he survived. The two then battle together, giving them the initial upper hand against Zenoheld who then starts to overpower them. At this point in the battle, Professor Clay informs Zenoheld that the Alternative System, a giant airship modeled after Farbros is complete and as a first objective it's target is 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 him and Gus just barely escaping the impact. Farbros links with the Alternative, and Zenoheld declares that his quest for intergalactic domination has begun.
