—Ultimate Dragonoid before evolving into Infinity Dragonoid
Ultimate Dragonoid is the second evolution of Drago before he evolves into Infinity Dragonoid
Ultimate Dragonoid was included in the Bakugan Arena commercial when it said "there are now 30 more new Bakugan to collect". But Ultimate Dragonoid was never released as a Bakugan toy.
Drago evolved into Ultimate Dragonoid after he fought Storm Skyress as Delta Dragonoid. Due to Storm Skyress being the Guardian Bakugan of Shun, the last Brawler Dan needed to defeat. He has markings on his wings which are now split and he also has two horns that are merged.
He defeated Alpha Hydranoid in episode 38, and then teamed up with him to defeat Centorrior and Druman but they needed a very precise stategy to beat them. He later appeared to battle Centorior and Druman again but this time with Runo's Haos Blade Tigrerra. In the end Drago beat Centorior and Tigrerra took down Druman, later Drago tried to beat Naga and save Wavern but he destroyed her on her own request and got the Infinity Core and evolved into Infinity Dragonoid.
In End of the Line, he appeared briefly in a flashback.
