You should see the looks on your faces! Priceless!

Mischievous Villains are evildoers who are playful, misbehaved, disrespectful, and often childish, as they don't always seek outright harm on others. They are very similar to Tricksters: however, mischievous villains cross the line when they allow their misbehavior or love of play to override such things as basic law and order, changing them from harmless pranksters to reckless individuals who can harm themselves and others.

Pure Evil can almost never be in this category, as mischievous villains often are comedic, but they can still in rare cases be.
