Alius Academy ArcEdit
Xavier is the captain of Alius Academy's strongest team, Gaia (receiving the title "The Genesis") and reveals himself in secret to Mark. Going under the alien name "Gran", he becomes dead-set on crushing the Raimon soccer team. Though he wasn't inherently evil, Xavier's devotion to his stepfather led him to become corrupt and carry out the orders of destruction under the guise of Alius Academy. After a climactic battle between the Raimon Eleven and The Genesis, Xavier is freed from his stepfather's influence and returns to a normal life for a brief while. He was also adopted for a while by Raimon Eleven's Alius Academy Arc Coach, Lina Blitz.
