Mr. Huffington, known in Japan as Kumazo Maeda (前田熊蔵, Maeda Kumazō) is Chumley Huffington's father and a former famous Duelist. Mr. Huffington visits Duel Academy to have his son pulled from his studies, as he believes Chumley was wasting his time at the school and would be better off at home working for him. However, Jaden managed to convince Mr. Huffington and Chancellor Sheppard to allow Chumley to fight for his right to stay. After a short but passionate Duel with Chumley, which results in his victory, Mr. Huffington realizes that his son has made friends at Duel Academy and allows him to stay. In the English dub, his voice may be a tribute to / parody of John Wayne.
In the Japanese version, Kumazo owns a sake company and has drinking problems, while in the English version, he owns a hot sauce company.
