Under Hot Wheels City live the Mutant Machines. Half animal, half machine, these creatures, born from a failed laboratory experiment, are lurking to conquer the world. Thanks to their spines modeled after those of animals, the cool-looking Mutant Machines don't drive in the traditional sense; instead, they can bend, stretch, and slither in unique ways. With the individual vehicles that can connect at the front and back to form a long Mutant Machine train, boys can experience the most exciting stories. The range includes Mutant Machines like Street Shark, Skullface Skeleton, and Power Tread Tanker. Cool action with the entire fleet for new, fantastic underworld adventures.
