The Mayhem Machine is a prodigious achievement of technical wonder and marvellous science. It is a unique creation, built by a rogue line in an automotive factory in Capek Street; some link its misterious builder to the legendary Young Golem; what's certain is this machine raw power and unlimited badassery.
It comes equipped by many luxurious extras, such as four wheels, a gear box, some seats. Even if it's a unique piece, it can still be upgraded to higher versions with a lot of elbow-grease and spare time: it is already designed to host a bar, many secret rooms and even entire floors!
Some have observed the Machine change its painted colours to better adapt to its evironment, not unlike a chameleon would do. That's why it's the apex predator in the mechanical devices' food chain. Another observed behaviour of its is the irresistible desire to... punch things! The Mayhem Machine punches, rams, lounges, tricks and treats for the sake of it!
It has been observed that the Mayhem Machine now serves the cause of Bendy Bandit's rebellion, and shuttles her and her minions around in their questo to free all the ultras.
