- For Dan Kuso's Guardian Bakugan, see Drago.
'Infinity Dragonoid' (インフィニティ・ドラゴノイド Infiniti Doragonoido) is the third and the final evolution of Dragonoid in Bakugan Battle Brawlers.
In The Good, The Bad and The Bakugan, Ultimate Dragonoid uses the power of the Infinity Core that Wavern gave him to defeat Naga.
In The Final Brawl, he continues his battle against Silent Naga
In Game Over, he continues his battle against Silent Naga and ends up winning, thanks to the other Bakugan (Alpha Hydranoid, Blade Tigrerra, Hammer Gorem, Preyas, Storm Skyress, and Angelo/Diablo Preyas).
After he absorbing both cores, Drago became complete by evolving into Perfect Dragonoid. After this, he said farewell to Dan and opens up a Dimension Tunnel to the core of Vestroia. He then returned both of the cores, creating New Vestroia and becoming the Perfect Core.
