"The name... is Wylde."
- Mark Wylde
He is a scruffy man with spiked black hair with sideburns. He has a five-o-clock shadow and wears dark round sunglasses. He wears a black tanktop and jeans, plastered with various belts and Metal Maniacs branding. He has a dark blue tribal tattoo on his right arm.
He is tough and has a short fuse, blaming his brother for sending him to prison.
- "Kurt’s younger brother Markie ‘Wylde’ Wylde is a fearlessly reckless racer. Buff and tattooed, Wylde has grown a great deal since he first started competing. Unlike many of the other Metal Maniacs, Wylde doesn’t race for the love of racing or fight for the love of fighting. He’s out to prove that he’s the best and — more specifically — better than his older brother." - Meet the Drivers description
The Greatest Challenge
Mark can be first seen driving in Kurt 's Sling Shot performing moves. Kurt confronts Mark to get out of his car after he stops. Mark later begs Kurt to recruit him to his team, he rejects him and drives off. Vert Wheeler recruits him to the Wave Rippers. Mark is one of the twenty-two drivers racing in the second leg.
Prior to the events of AcceleRacers, his brother Kurt got him involved in a shady "business deal", but then backed out on him when he refused to give up. As a result, Mark went to prison for two years and after he was released, he refused to acknowledge Kurt as his brother after he abandoned him and joined the Metal Maniacs.
Wylde becomes the leader of the Metal Maniacs after Tork allowed him to win in a race spanning from the Acceledrome to the Handler Proving Ground and back. However, in spite of this, his members refused to listen to his orders. This causes the team to fall in a state of anarchy for the remainder of the movie. In the Junk Realm, Wylde failed to follow the apex, which at the same time, a wrecking ball launched him and his car off the track, landing in a pile of debris and losing Wylde's sunglasses. He failed to activate his EDR in time because he was knocked out, resulting in him getting trapped inside the realm, and was later captured by the Drones then flathead fury got abandoned in the junk realm and several hours later wylde wakes up in the drones headquarters
The Ultimate Race
Still in captivity, Wylde's left arm was replaced with leftover Drone parts. He appeared to be battered up because the drones must've tortured Wylde. Wylde managed to finish off RD Kadeem, who nearly killed Kurt in a fight battle. The brothers use the EDR from the Battle Spec to escape from Drone City, only to be surrounded by more Racing Drones on Earth. The brothers fought through the Acceledrome and escaped inside a hijacked Sweeper before the building blew up into flames. They realize Vert is still missing, and they continue their search to find him.

- Mark Wylde entered the fewest realms of any human driver, entering only 5.
- Despite him driving Chevrolet Corvette Stingray in the movie, the World Race game features him with Golden Arrow, a Hot Wheels car, probably due to licensing issues.
