One-Off Villains are enemies and bad guys who serve the purpose of being the villain for a single adventure.
Despite being called "One-Off", occasionally a villain on this list may appear for 2 sessions. Sometimes they are introduced once, and then disposed of the next time. In any case, any villain who isn't carried along in the plot for longer than 2 sessions is considered disposable. Villains who continue to reappear for 3 or more games can be considered Reoccurring Villains.
