Aiger Akabane, known as Aiga Akaba in Japan, emerges as the main protagonist in Beyblade Burst Turbo. Witnessing Valt Aoi and Wonder Valtryek’s strength inspires him to forge his own Turbo Beyblade, Z Achilles 11 Xtend, launching his Blader journey. His core ambition—to challenge and defeat Valt—culminates in victory through his Turbo Beyblade’s dark power, though this triumph exacts a toll on his character. Aiger possesses lighter skin, turquoise eyes, and maroon hair and eyebrows, distinguished by a red "A" tattoo on his left cheek and facial bandage strips. His Turbo-era attire includes a burgundy Letterman jacket with precise detailing, black shorts with suspenders, and burgundy sneakers. After battling Valt, he adds a dark-blue hand brace to his left wrist. In Rise, Surge, and QuadStrike, he grows taller and updates his wardrobe to long-sleeved jackets, patched jeans, and redesigned footwear, retaining the celestial-blue hand brace introduced in Rise. During Beyblade resonance, his hair turns crimson and escapes its blue rubber band. Personality-wise, Aiger begins as a hot-headed, competitive Blader who loathes losing, particularly after his initial defeat by Valt. Growing up on a farm, he bonds deeply with animals, even sleeping in Beigoma Academy’s petting zoo to stay near them. Though battle-strategic like Valt, he often brags about invincibility. A critical shift occurs during his clash with Free in episode 25, where Phi’s dark aura corrupts his resonance with Achilles, amplifying his ruthlessness and stubbornness. This drives him to overextend Achilles, destroying Wonder Valtryek. He dismisses warnings from figures like Shu Kurenai about his dark resonance and exhibits poor sportsmanship. Z Achilles’ destruction by Phi becomes a turning point, restoring his calmer, sportsmanlike demeanor. In Rise, Surge, and QuadStrike, he matures—accepting losses gracefully and heeding advice—though occasional overconfidence lingers. His Beyblades evolve across seasons: Turbo features Z Achilles 11 Xtend, upgraded to Z Achilles 11 Xtend+ (later destroyed by Phi), then Turbo Achilles 00 Dimension. Rise introduces Union Achilles Convert Xtend+ Retsu with Union Sword attachments. Surge showcases Infinite Achilles Dimension’ 1B, utilizing Infinite Sword and Infinite Shield for combat adjustments. QuadStrike deploys Zeal Achilles Giga-Q Massive-Q+Quattro II-10. Battle techniques include signature moves like Z Breaker (height-driven downward strikes), Z Defense (attack deflection), Turbo Whip (slashing assaults), and Turbo Crush (shield-to-smash combos). Advanced maneuvers encompass Lightning Launch—synchronizing for temporary speed and power surges—and Hyper-Flux, a golden illuminated state boosting his Beyblade’s capabilities. Aiger’s journey sees him become World Champion by defeating Valt in Turbo, defend his title in Rise’s Battle Island Tournament, and compete in Surge’s Legend Festival and Ultimate Tag Series as S-Tier #3. Between Surge and QuadStrike, Valt reclaims the World Champion title, but Aiger returns for QuadStrike’s Champion’s Challenge and Lodestar Battle Tournament. His character arc progresses from a wild, ambitious newcomer to a corrupted competitor, then into a wiser, balanced Blader. His bond with Achilles remains pivotal, reflecting his evolution from pursuing power recklessly to valuing resilience and mentorship. This transformation unfolds consistently across all seasons.
