Malefactors are troublemakers who engage in cantankerous and loutish behavior and acts of vandalism. They tend to be younger villains, but can be of any age and share some similarities to bullies. Malefactors generally engage in antisocial behavior for fun, or as a form of rebellion.

Examples of Malefactors include Vandals, Thugs, Gang Members (especially Street Gangs), and villains that generally have a bad attitude and lack of respect for other people or society's norms.
