A former member of Vert's old team, the Wave Rippers. Far from the innocent racer who reconciled with his older brother, Kurt Wylde, at the end of Highway 35, Markie is aggressive, short-tempered, and easily riled by his older brother and Tork. Apparently before the Acceleracers saga began, Kurt talked Markie into joining a "business deal", but he ended up arrested when things went wrong and he refused to give up. After two years in prison, Markie joined the Metal Maniacs and refused to acknowledge his brother for abandoning him. He is determined to prove himself, even if it means breaking the rules. After the Metro Realm, he gets extremely angry towards Monkey and Tork; at Monkey for losing his car to the Sweeper, and at Tork for letting Monkey take the car in the first place. After this, Tork doesn't let Markie drive in the Realms because of his determination to get back at Kurt, other than winning. His first car is "Spinebuster", his second is "Flathead Fury". His previous World Race Wave Rippers car was a Corvette Stingray. It is unknown what happened to it after the World Race. He was a convict and him being a racer meant that he probably tried to drive away when the police were after him. Seeing as he was caught with his car might have been taken as evidence and later auctioned off. Between Tork letting Monkey race in and lose his car, and Tork not letting him race, Markie had enough of Tork and challenged him for leadership of the Metal Maniacs, racing to Dr. Tezla's old base and back. In the final leg he and Tork were neck-and-neck for the lead. But Tork remembered Tone's crash during their race. The shock of almost reliving the event caused Tork to hit the brakes, letting Markie win. However, his victory was short lived as a racing portal had opened when he and Tork were racing, and the other Maniacs had left. When the next portal opened Markie tried to get back at Tork by having PorkChop race instead of him. PorkChop, however, still had respect for Tork and wouldn't race in Tork's place. No one else on the team would either. Outraged, Markie left the team. Though in the Junk Realm, Markie still tried to get the Maniacs to do what he said. In the Junk Realm he crashes his car and has been captured by the Drones, leading Kurt to bring the Metal Maniacs and Teku together to infiltrate the Drones' headquarters using a Sweeper, Kurt soon sees that the Drones had replaced his arm with a Drone arm. After saving Kurt from a Drone controlled Kadeem, Mark thanks Kurt for coming back for him, which ends their conflict for good.
