Dragonoid, known as Drago, serves as Dan Kouzo's primary partner Bakugan throughout Bakugan: Legends. This dragon-like Bakugan wields the Pyrus attribute and exhibits significant evolutionary potential fueled by Nova Light energy. Drago stands central to confronting the planetary crisis threatening both Earth and Vestroia. When the gate linking the two worlds destabilizes, Drago accompanies Dan to Vestroia for investigation. There, the character encounters The Swarm, destructive entities draining planetary energy. Exposure to Nova Light during their escape triggers Drago's evolution, unlocking enhanced combat capabilities. This transformation also empowers other Bakugan allied with the Awesome Brawlers upon their return to Earth. Drago reveals crucial history about Hanoj, identifying this entity as an ultimate Bakugan sealed within Vestroia after nearly destroying it. The character participates in collective battles against Hanoj's Swarm forces. When Hanoj emerges personally to drain Earth's energy, Drago confronts it directly alongside Dan and allies. Drago's knowledge informs the strategy to initiate a Battle Judgement against Hanoj, offering energy rights based on combat outcomes to buy time for developing technological countermeasures. Training for this Battle Judgement leads Drago and Dan to discover Nova Cores, specialized energy manifestations resonating with their Nova Light. These Cores unlock new combat techniques: Drago obtains Nova Baku-Fusion during a battle against Chad, while Magnus later acquires Baku-gear from another Core. Drago demonstrates the Nova Technique, which involves landing on specific Nova Cores during battles to activate unique powers like Baku-Fusion or Nanogan enhancements. Mastering this technique becomes essential for the final confrontation with Hanoj. Physical representations of this incarnation feature light-up elements and specialized transformations. The Nova Dragonoid variant incorporates illumination effects during its pop-open Baku-Action sequence. Associated Character Cards indicate variable B-Power ratings up to 900 and Damage Ratings reaching 5.
