Julie Makimoto is a Subterra-attribute Bakugan brawler from Bakugan Valley, Australia, who later settles in Bayview. Childhood friends with Billy Gilbert, their bond deepens into romance by the original series’ end. She navigates a complex dynamic with her older sister, Daisy Makimoto, initially wrestling with insecurity before proving her worth in the Doom Dimension—a pivotal moment that triggers her guardian Bakugan Gorem’s evolution into Hammer Gorem. Her early arc centers on idolizing Dan Kuso, sparking rivalry with Runo Misaki, though the pair eventually forge a strong friendship. Julie’s partnership with Gorem emerges after losses against Billy, who briefly aligns with Masquerade. The bond cements her place in the Battle Brawlers, where she employs aggressive tactics and tenacity in combat. During New Vestroia, deprived of her captured guardian Bakugan, she supports the Resistance from the sidelines, coaching Mira Fermin in Subterra strategies for pivotal matches like the duel against Gus Grav. Without a Gauntlet for the updated brawling system, her direct battlefield involvement wanes as the narrative prioritizes other characters. In Gundalian Invaders, now based in Bayview, she balances waitressing and cheerleading while mentoring Jake Vallory, urging him to craft a distinct battle style. Her guardian Bakugan shifts to Taurus, though she rarely engages in active brawling. By Mechtanium Surge, she transitions to a news reporter role in Bakugan City, with guardians like Roadem, Adgaran, and Hippower receiving scant narrative focus. Her wardrobe evolves across seasons, featuring midriff-baring tops and shorts that mirror her outgoing demeanor. The original series highlights a pink crop top, New Vestroia a rainbow-striped shirt, and Gundalian Invaders a navy-blue belly shirt—each reflecting her journey from a spirited, flirtatious teen to a composed young adult. Her role diminishes progressively, shifting from core Battle Brawler to secondary figure—a trend reflecting the series’ broader marginalization of female protagonists in later arcs. Despite reduced screen time, she leaves a legacy through mentorship and sustained bonds with original teammates, anchoring her enduring influence within the group’s evolving dynamics.
