Belowski, known in Japan as Mokeo Motegi is an Obelisk Blue student and the former top student of Duel Academy who has the power to communicate with Duel Monsters. Belowski is a laid-back, carefree, peace-loving boy who isn't afraid to take a nap at the most precarious of times.
Those in his presence gradually fall asleep without proper precautions and therefore he is confined to his own personal dorm, "a secluded paradise within the depths of the school" as Dr. Crowler calls it.
Because of his unusual talent in making those around him woozy, Crowler sets up a duel between Belowski and Jaden Yuki in the hope that Belowski's power might affect Jaden long enough for him to lose the duel, thus expelling him from the academy. However, Jaden's excitement and passion for dueling overwhelms Belowski's power and he ends up winning anyway, in which Belowski promptly dozes off after their duel
