Delta Akane, also known regionally as Delta Zakuro, debuts as a top BC Sol Blader. He initially wields Heat Salamander 0 Unite before claiming his signature Gamma Beyblades. Tall and pale with striking red eyes, he sports distinctive sea-green hair styled with long bangs covering his left eye. His attire typically features a white dress shirt with a deep crimson tie, a black buttonless vest, gray pants, black loafers, and a red jacket boasting pink interior lining, dark-red borders, and a cerulean waist belt. During Beyblade resonance, his left eye emits a crimson aura; this vanishes after his Bey's destruction but reappears following his emotional recovery. Calm, reserved, and detached, he draws comparisons to figures like Shu Kurenai and Fubuki Sumiye. He exhibits fierce protectiveness over his Beys, notably snatching Venom/Erase Devolos from Dante Koryu when handled without permission. After obtaining Devolos, arrogance surfaces. He frequently declares "only one star in the sky can shine the brightest," believing he alone deserves that position. This drives him to challenge powerful opponents like Aiger Akabane and the Risen 3, ultimately resulting in his Beyblade's destruction. Profound despair follows, leading him to wander the streets heartbroken until Valt Aoi helps rebuild his Bey and confidence. This recovery fosters newfound openness to friendships with Dante and Arman Kuroda, though his reserved core remains. His journey starts as a BC Sol student under Valt Aoi, witnessing Sword Valtryek and Hyper-Flux. Inspired, he creates Venom and Erase Devolos Vanguard Bullet, achieving Hyper-Flux synchronization. After winning the European Championship, he joins the Risen 3 and departs BC Sol. He later defeats Dante in the Bey Carnival finals but suffers a crushing defeat against Arthur Peregrine, resulting in Erase Devolos' destruction. Returning to BC Sol in despair, Valt aids in rebuilding his Bey into Master Devolos Generate and advises accepting Dante's support. Delta subsequently defeats Arthur in a rematch and joins the Victories team, contributing to their victory against Team Inferno. In the Beyblade Burst Surge manga, he reappears as a Legendary Blader ranked S-Tier #9, wielding Lightning Beyblades Demise Devolos 4Turn Merge' 1D and Abyss Devolos 5 Fusion' 1S. During this arc, he mentors Hikaru Hizashi on battle strategies after initially rejecting battle requests from Hikaru and Hyuga Hizashi. His Beyblade evolution progresses from Heat Salamander 0 Unite to Gamma-type Venom/Erase Devolos Vanguard Bullet. Post-destruction, he rebuilds it into Master Devolos Generate. In the Surge manga, he upgrades to the Lightning system with Demise and Abyss Devolos. His Beys feature unique gimmicks like the Bullet Driver splitting into a mini-Bey for coordinated attacks. Special moves include Dual Phantom (Bullet tip splits to release the mini-Bey), Bullet Attack (mini-Bey weakens opponents), Bullet Cannon (striking the mini-Bey for increased speed/power), Shining Cross (pincer attack with both Beys), and Hyper-Flux (synchronization enhancing speed/power). Master Devolos techniques are Master Upper (uppercut) and Master Smash (high-speed collision after rail acceleration). Key relationships involve a rivalry with Dante Koryu, initially dismissed but later accepted as a friend. His bond with Devolos includes literal conversations, the Bey's spirit demanding battles to "consume Bey light." He harbors strong animosity toward Arthur Peregrine for destroying his Bey and interfering in his championship match. He views Aiger Akabane as a primary target, believing victory over the World Champion will solidify his status as the "brightest star."
