Mitchell McClurg, better known as Monkey, is a member of the Metal Maniacs, as well as the team's mechanic. He is very hyperactive, jumpy, and "afraid of everything" but is also very friendly. Monkey drives rolling thunder and it got destroyed in the storm realm and Porkchop brings him a replacement but can't drive it in the metro realm due to nolo smashing the windshield he drives spine buster in the metro realm instead but gets destroyed by the drone sweeper causing wylde to throw a tantrum and Rollin' Thunder is last seen in the Pipeline Realm because Porkchop snapped the door off when attempting to go into the Junk Realm and help the Metal Maniacs get rid of the sweepers by riding Old Smokey, destroying the truck in the progress!
Monkey can be described as a bit jumpy and nervous, but is also very friendly and despite being an Metal Maniac also very Neutral. He usually hangs around Porkchop, and has a crush on Lani. Though, he is also very smart, as shown when he built the robot "Sparky" and created a new version of Nitrox called Nitrox 3... and a half!
Monkey's first car was Rollin' Thunder (which couldn't handle going 300MPH, as the needle on his speedometer broke). The car is destroyed during the Storm Realm when he attempted to take on RD-L1 (which was chasing him) and the drone destroyed his car with an electric ball. Porkchop brings a replacment Rollin' Thunder to the Acceledrome. The second Rollin' Thunder mysteriously vanishes between "Breaking Point" and "The Ultimate Race", though it could have been destroyed in the Ruins Realm, from then on Monkey drives Rat-Ified, which he sacrifices to take over a Sweeper in the effort to save Markie and drives spine buster in the metro realm due to nolo smashing the rollin thunder windshield
- Monkey is the first Metal Maniac newcomer to enter a racing realm
- Monkey is the first and currently only person to reverse engineer a Dr. Tezla "Creation".
- Monkey contributes the most into saving cars in the realms:
- He created a new Nitrox boost, Nitrox 3 1/2; which helped Taro escape the Drones Headquarters and make it to the end of the realm before it closed.
- He brought back racing drones tires: which helped all the drivers stay on the road in several realms.
- He put and E.D.R and a Nitrox booster in Old Smokey, which later saves Wylde, Tork, and Taro from drones.
- Monkey somehow has a picture of Vert's mom on his dresser. It can be seen before the Metro Realm opens.
