'''Belowski''', known in Japan as '''Mokeo Motegi''' (茂木もけ夫, ''Motegi Mokeo'') 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 laidback, carefree, peace-loving boy who isn't afraid to take a nap at the most precarious of times.

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.

However, [[Jaden]]'s excitement and passion for [[duel]]ing overwhelms [[Belowski]]'s power and he ends up winning anyway, in which [[Belowski]] promptly dozes off after their [[duel]]. [[Belowski]] returns during the second year as one of the few [[Obelisk Blue]] students left untouched by [[The Society of Light]] and participates in a [[duel]] of the [[Genex Tournament]] against professional [[duelPro League|professional]]ist duelist [[Elroy Prescot]], who becomes so tired from the boy's special ability that he forfeits the match.  He is last seen rejecting [[Crowler]] and [[Jean-Louis Bonaparte|Vice-Chancellor Bonaparte]]'s offer to become a representative of the school and choosing to take a nap under the shady trees instead.

His character in the dub, as well as the title of his debut episode, are based on the film, [[Wikipedia:The Big Lebowski|The Big Lebowski]]. He speaks like a 1970's rebelling hippy, using terms such as "The Man" and "The Establishment". His Japanese given name is a pun off the name of his key card, "[[Mokey Mokey]]".

[[Belowski]] plays a [[Mokey Mokey]] [[Deck]], filled with low-level monsters. His main strategy is to destroy his own [[fairy]]-[[type ]] monsters, thus activating the [[effect]] of "[[Mokey Mokey Smackdown]] " and increasing "[[Mokey Mokey]]'s " [[ATK]] to 3000.

By combining this with "[[Human-Wave Tactics]]", [[Belowski]] is able to keep up a supply of [[monsters]] as fodder to trigger [[Mokey Mokey Smackdown|"Smackdown]]'s " [[effect]], at the [[Costs|cost]] of his own [[Life Points]] , but he can easily bypass this disadvantage with Life Point-increasing cards such as "[[Gift of the Mystical Elf]] " and "[[Mystic Wok]]".
