When MK escaped with the Golden Staff, Red Son uses his Inferno Truck to go after him. The truck eventually stuck in a narrow street, letting MK outran Red Son the second time on his Cloud Board. Red Son eventually abandoned it and uses the cockpit of the truck, a race car instead.
Red Son used the Inferno Truck to escape with the Skeleton Key after taking it from MK and Mei. Mei later used her bike to chase down Red Son. After Red Son ejected the race car out of the Inferno Truck to get Mei off of his tail, Mei jumped out of her bike and destroyed the Inferno Truck with the Dragon Blade.
