Lain Valhalla, known as Lean Walhalla (レーン・ヴァルハラ, Rēn Varuhara) in Japan, is the main antagonist of the anime/manga series, Beyblade Burst Surge. He fights with his Beyblade, Vex Lucius Mobius 2D. He was a member of the Raging Bulls, and the former student of Shu Kurenai. Following his loss to Shu, Lain evolved his Bey into Lucius Endbringer Kou Drift.
Lain is a tall boy with pale skin, yellow eyes with thin rings, pointed incisors, magenta markings on his face, and spiked up magenta hair with lighter pink highlights.
His attire consists of a dark-blue sweatshirt with light blue markings on the front and a mint green fur collar, indigo pants, red boots with mint green collars and light-rose soles, three red-buckled violet belts on the arms and two on the thighs, a harness-like violet belt on the torso with red buckles and red studs, and a dark-red, square-cuffed fingerless glove on his left hand. When he's not Beyblading, Lain wears a black coat with four violet buttons and red-buckled straps on the chest section.
When he resonates with his Beyblade, Lain's eyes and facial markings glow. After his power increases, the light pink highlights in Lain's hair glow cyan and the belts around his arms, legs, and torso break loose.
