Throughout the series, Chumley participates in only two duels: the first against his father, Mr. Huffington (Kumazo Maeda), and the second against Vellian Crowler (Cronos de Medici). His father believed that his son's efforts at Duel Academy were worthless and that he would be better off leaving. To put an end to the conflict, Chumley struggled valiantly against his father's special tactics, but ultimately lost. Despite this, he allowed his son to continue his studies, as he saw that Chumley had actually learned something, and that his friends would always support him.
Maximillion Pegasus (Pegasus J. Crawford) offers Chumley a job at Industrial Illusions as a card designer nearing the end of the first year. In order to determine whether or not he will be permitted to leave the school, Crowler duels with him in one final test. Although Chumley manages to hold his own, even getting the chance to play the first card of his own creation, [[Ayers Rock Sunrise]], he is again defeated. Crowler, however, lets him move on regardless, impressed by how far in his studies he has come.
Chumley returns with Pegasus during the Genex tournament to give Jaden a new card, Skyscraper 2 - Hero City, to aid him in his duel with Frantz, a fellow card designer who stole the only remaining copy of The Winged Dragon of Ra from Industrial Illusions.
