Mater Private Eye
In Mater Private Eye, Big D is the mastermind of a counterfeit tire traffic, which produced counterfeit Lightyear tires (labeled "Lite Yeer") that caused blowouts on those who were equipped with them. He had carnapped Tia's sister Mia.
He first was mentioned by Tia when she said that she last saw Mia working for Big D at his nightclub. Then at the nightclub, Mater asks Carmen if she's seen Mia anywhere, and Carmen says she saw her a few days ago with Big D, but with the smell of salt like the ocean.
When Mater investigated the docks, he was uncovered by a crane and captured by Big D's henchmen. Big D then reveals himself. Mater said that he will tell the DA. Big D replies he won't tell the DA anything. Upon seeing Lightning McQueen and other police cars arrive, he tried to flee, but Mater moved the crane with his tow hook and made it drop a crate of tires on Big D, which were revealed to be counterfeits. Lightning and the police then arrested Big D.
