Alexander "Xander" Shakadera, known as Kaiza Shakuenji (灼炎寺カイザ, Shakuenji Kaiza) or just Xhaka (シャカ, Shaka) in Japan, is a recurring character who appears in the anime and manga series, Beyblade Burst. He is a member of the Supreme Four, as well as the leader and founder of his own team, the Sword Flames. He was formerly a member of the Big Five. His current Beyblade is Xiphoid Xcalius Xanthus-Q Xtend+-Q+Sword-1. He is currently the leader for SB Rios, and leads them through the World League. He returns in the Superking manga as a legendary blader. Xander is very tall (reaching about 6 ft) and has red-orange spiked hair, triangular teeth, and red eyes; he also has a muscular build due to his martial arts background. His regular attire consists of a tight black top which exposes his midriff, a red fur-trim vest which has a brown belt-type fastener at the bottom over it, brown pants with two red stripes at the ends of each leg, a yellow belt, and black gauntlets over his arms. Despite having the appearance of a fully grown adult, he is actually only 11 years old, the same age as Valt and Shu (evidenced by the fact that they were all in kindergarten together). In Turbo, Xander now wears a red, fur-trim vest with a brown border, a brown belt with a silver buckle adorned with an "X", brown pants with a yellow stripe on each side, and black boots with a red border and yellow wraps at the ankle area. The fur trim is visibly enlarged and resembles a fur-coat collar.
