The Mutant Formally Known As 'The Beast of AAARGH!' is a reclusive and ingenious scholar in the art of violence blood-sports and has a past that is mostly kept secret from all the other members of the Mean Machine. Because it mostly doesn't exist.

The Beast of AAARGH! Is actually a series of cloned mutants kept by the enigmatic Doctor Mxylpxyl in an attempt to create the ULTIMATE BIOWEAPON TO RULE THE WORLD WITH.

Unfortunately they tend to wear out after a few days of being spawned, so they instead choose to put the mask on every new clone and pretend it's still the same beast after all this time.
