Ep 5. Into the Darkness! Dark Doomscizor!

As the fourth round of the Beyblade World Championship continues, Valt and Rantaro prepare for their match. Meanwhile, the rest of the team are worried about Shu, who has been missing since his defeat in the previous round. After being captured by the Snake Pit organization, Shu finds himself face to face with the leader, Xander. Xander reveals that he has been searching for a powerful beyblade to add to his collection, and believes Shu's Spryzen Requiem is the perfect addition. Xander puts Shu's beyblade to the test, battling it against his own Doomscizor. Despite Shu's best efforts, his beyblade is unable to withstand the power of Doomscizor's special move, leaving Shu in shock as he is defeated. Back at the arena, Valt and Rantaro begin their match. Rantaro shows off his skills with his spinning top, Wild Wyvron, but Valt manages to use his special move, Valtryek Rush Launch, to knock Rantaro out of the arena. Valt is declared the winner and moves on to the next round, but he can't shake the feeling that something is wrong. As the episode ends, Shu is left to wonder what Snake Pit has planned for him, and Valt realizes that his friend is in danger.
