Daniel "Dan" Kuso, a fiery human protagonist from Wardington, forges a legendary bond with Drago, his Pyrus Dragonoid partner capable of evolving into Neo, Cross, and Helix Dragonoid forms during battles. At 15 in the New Vestroia conflict, he joins the Bakugan Battle Brawlers Resistance to free enslaved Bakugan from Vestal forces wielding Dimension Controllers. His reckless impulsiveness and competitive drive prompt early missteps, including abandoning Drago after a clash, but defeats like his loss to Gus Grav spark introspection. Through reconciliation with Drago and tactical growth, he tempers his brashness into calculated strategy. Dan’s evolving appearance in New Vestroia features a gold-trimmed long-sleeved overcoat with dark shoulder pads layered over a light blue sleeveless shirt, white pants edged in blue, and black fingerless gloves. He wields a Pyrus Scorpion Trap Bakugan gifted by Resistance leader Mira Fermin and a battle gauntlet activated by the command *"Gauntlet, Power Strike!"* His rivalry with Ace Grit, a Darkus brawler, ignites during a stalemate duel that fosters grudging respect. Mentorship emerges in his dynamic with Baron Leltoy, a Vestal youth he trains to conquer insecurity. Critical arcs involve Drago’s capture by Spectra Phantom—later unmasked as Mira’s brother Keith—and Drago’s retrieval via a forbidden card and aid from Apollonir. Absorbing Six Attribute Energies from the B.T. System propels Drago’s evolution, countering threats like Zenoheld’s Alternative Weapon System. Dan’s leadership unites allies to dismantle Vestal control, though his temper flares during tactical disputes. Post-New Vestroia, Dan moves to Bayview and Bakugan City, confronting challenges from stabilizing Code Eve’s power to thwarting Gundalian invasions. He maintains persisting bonds with original allies like Runo Misaki and Shun Kazami, alongside subtle romantic undertones with Runo. His parents, Miyoko and Shinjiro Kuso, bolster his journey, with Shinjiro mirroring Dan’s exuberance. Expanding his arsenal, Dan temporarily allies with Bakugan like Apollonir and Dragonoid Colossus, deploying Battle Gear and Mechtogan in later conflicts. Though power instability leads to losses in advanced seasons, his reputation as a legendary brawler resonates across factions from Earth, Vestal, Neathia, and Gundalia.
