Bakugan Battle Brawlers (2007) : 2x45

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.
