The doctor trained the monkey Wheeler as a Duelist. After Wheeler escaped from the lab, he, Tatewaki and a man armed with a tranquilizer gun tracked him down and found he had taken Jasmine captive. They explained some of their project to Jasmine's friends and Jaden Yuki challenged Wheeler to a Duel for Jasmine's freedom. During the Duel, Jaden realized how poorly the doctor had been treating Wheeler and keeping him away from his family and asked that Wheeler be let free. The doctor then offered to let Wheeler be with his family, by taking them to the lab too. He ordered the armed man to capture the other monkeys, but Lyman Banner and Pharaoh interrupted. Banner threatened to report the doctor and his men for animal abuse, leaving them no choice but to free Wheeler.
