Misfits & Mayhem is a TTRPG mechanics engine I developed that is meant to be easily customizable to any setting or story. The mechanics are modular, meaning everything outside the baseline rules can be included or excluded based on the type of story you want to tell. It is derived from the Powered by Kids on Bikes system and uses many of the same mechanics, but in my mind, it's distinct enough to warrant its own name and SRD.
