Valt Aoi (蒼井バルト, Aoi Baruto) is the main protagonist of the anime and manga series, Beyblade Burst and Beyblade Burst Evolution. He is an enthusiastic Beyblader who founded Beigoma Academy's Beigoma Academy BeyClub, where he served as the team's captain. He competed in the National Tournament with Victory Valtryek Boost Variable and was the runner-up, but gained enormous popularity due to his incredible performance.
In Beyblade Burst Evolution, Valt's Victory Valtryek was evolved into Genesis Valtryek 6Vortex Reboot and was scouted by BC Sol to participate in the World League, where he served as team captain. Following their tournament win, Valt upgraded Genesis Valtryek into Strike Valtryek and competed in the International Blader's Cup, where he defeated his long-time best friend and rival, Shu Kurenai, in the tournament finals for the title of "World Champion".
In Beyblade Burst Turbo, Valt entered his second year as the World Champion and evolved his Strike Valtryek into Wonder Valtryek 12 Volcanic to prepare for upcoming competition. With his Wonder Valtryek, he successfully defended the title against multiple challengers, including Big Five members, Lui Shirosagi and Silas Karlisle, but he lost to Aiger Akabane in a match that destroyed his Wonder Valtryek.
Even after the loss to Aiger, Valt continued to pursue his Beyblading career and seeked to help Aiger Akabane, who had became possessed by Z Achilles and he evolved his shattered Wonder Valtryek into Turbo Valtryek. He also won back his title of World Champion from Hyde, which he later lost to Aiger again.
In Beyblade Burst Rise, Valt returned with his brand new Gamma Bey, Sword Valtryek Blitz Power Retsu. After revealing Sword Valtryek's Hyper-Flux, Valt inspired two BC Sol rookie bladers, Dante Koryu and Delta Zakuro, to set out on their own journeys to achieve Hyper-Flux.
As "The Legend of Legends" and Number One Blader in the World, Valt returned in Beyblade Burst Surge with his new Lightning Bey, Brave Valtryek Evolution' 2A, to start a Blading revolution and compete in the Legend Festival and Ultimate Tag Series tournaments, becoming the former tournament's runner-up.
In Beyblade Burst QuadDrive, Valt returned as the season's deuteragonist, reclaiming his role of the reigning World Champion. He battles with his newly evolved Quad Bey, Salvage Valtryek Shot-7. Following a loss to Rashad Goodman, he evolved his shattered Salvage Valtryek into Ultimate Valtryek Legacy Variable'-9.
