Julie Makimoto, also recognized as Julie Hayward in the Japanese adaptation, emerges from Bakugan Valley in Australia as a recurring figure distinguished by her tanned complexion, long pinkish-white hair swept into a side ponytail with left-parted bangs, and vivid blue eyes. Her wardrobe consistently aligns with summer aesthetics, highlighting crop tops, belly shirts, and shorts that expose her midriff and legs. Seasonal variations define her style: a pink crop top paired with white boots during her debut, vibrant rainbow half-shirts and red shorts in later arcs, and darker-toned attire like blue or black tank tops in subsequent appearances. Beginning as a Subterra brawler allied with Hammer Gorem, her journey progresses from virtual interactions to physical integration with the Battle Brawlers. Early struggles involve navigating insecurities fueled by comparisons to her accomplished older sister, Daisy, and mending ties with childhood friend Billy Gilbert after his brief alignment with the antagonistic Masquerade. A defining trial orchestrated by the ancient warrior Clayf forces her to confront an illusion of Daisy, catalyzing Gorem’s evolution into Hammer Gorem and marking her embrace of self-worth beyond sibling rivalry. Her dynamic with Billy shifts from camaraderie to romance, solidified through joint battles against foes like Tricloid and unwavering support during clashes with the Vexos and Gundalian armies. Initial friction with Runo Misaki over shared admiration for Dan Kuso softens into friendship as Julie’s affections pivot toward Billy. Later arcs reposition her from frontline combat to mentorship. In New Vestroia, she coaches Mira Fermin on Subterra tactics and aids anti-Vexos resistance efforts, though her absence of a gauntlet restricts direct battle involvement. Relocating to Bayview during the Gundalian conflict, she balances waitressing and cheerleading while mentoring novice Subterra brawler Jake Vallory. By *Mechtanium Surge*, she resurfaces in Bakugan City as a news reporter, remaining peripherally involved until a fatal encounter with Mechtavius Destroyer—a death later undone through timeline alteration. Characterized by a lively, outgoing nature tempered by tactical acumen, she consistently uplifts allies through encouragement and guidance, exemplified in her support of Mira and Jake. Though her narrative prominence wanes over time, her arc illustrates a deliberate shift from competitive brawling to community-focused roles, preserving connections to her core team while pursuing independent aspirations.
