Delta Zakuro, also called Delta Akane in Japan, emerges as a central figure in the Beyblade Burst series, first appearing as a pivotal deuteragonist. His tall stature, pale complexion, and sharp red eyes contrast with his sea-green hair, swept into long bangs masking the left side of his face. He dresses in a crisp white shirt, crimson tie, and black vest layered beneath a red jacket with a pink-lined interior, paired with gray pants and a cerulean belt. Known for his aloof, reserved nature, Delta maintains a detached air, dismissing others with cool indifference. His obsession with strength fuels relentless Beyblade training, championing self-reliance above all. Early encounters expose his icy arrogance, epitomized by his mantra — “the sky only needs one star” — a declaration of his quest to eclipse all rivals. This drive pushes him to confront elite bladers like Aiger Akabane and the Risen 3, though overconfidence shatters his original Beyblade, Venom/Erase Devolos Vanguard Bullet, during a rematch against Arthur Peregrine. Crushed by defeat, Delta spirals into desolation until Valt Aoi rekindles his resolve, inspiring the creation of Master Devolos Generate. This Beyblade embodies his emotional rebirth and tactical refinement. Post-recovery, he softens, embracing teamwork and forging bonds with Dante Koryu and Arman Kusaba, eventually acknowledging them as allies. His strategic prowess later aids the Victories’ triumph over foes like Arthur’s Inferno in team clashes. The Beyblade Burst Surge manga reintroduces Delta as a Legendary Blader (S-Tier #9), wielding upgraded Lightning-class Beys: Demise Devolos 4Turn Merge' 1D and Abyss Devolos 5 Fusion' 1S. Reluctant to mentor novices like Hikaru and Hyuga due to their unpolished tactics, he eventually refines their skills under Valt’s persuasion, showcasing his matured mentorship. His Beyblade evolution traces his arc: from Heat Salamander and Arc Balkesh to Venom/Erase Devolos. After its destruction, Master Devolos Generate emerges with innovations like the Generate Driver’s retractable tip for calculated strikes. Signature moves like Hyper-Flux and Dual Phantom leverage synchronization and precision, deploying mini-Beyblades to disrupt opponents. Key relationships shape his trajectory. Initially clashing with Dante over Valt’s attention, Delta grows to respect his rival’s growth. His bond with Valt evolves from mentorship to a balanced partnership, pivotal in his post-defeat recovery. Triumph over Arthur Peregrine not only avenges past humiliation but solidifies his legacy, intertwining rivalry with redemption. Physical traits mirror his internal shifts. When synced with Devolos, his left eye flares with a crimson glow — a trait dimmed after the Bey’s destruction but reignited with renewed purpose. This visual metamorphosis parallels his journey from solitary ambition to collaborative strength.
