Tricksters

Tricksters are antagonists and villains that often appear to be more of an annoying nuisance than a outright fearsome or dangerous enemy. A Trickster antagonist/villain may take many forms of deception, from disguised con artists to mischievous imps with so much thrill. These antagonists and villains enjoy pulling pranks, engage in hoaxes for attention, cheating the unsuspecting public, or generally screwing with the hero, often moreso than doing anything actively malicious. Adventures with trickster-type villains tend to be light and comedy-oriented, and the hero typically finds a way to defeat them non-violently (or given the storytelling, having the heroes foil these antagonists/villains in a equally deceptive and unpredictable way if the heroes are also happen to be sly tricksters themselves).

Sometimes, there may be a lesson learned from the trickster, even if it's unintentional; the best example of such a character is Bill Cipher, who torments the Pines family, especially Stanford and Dipper.

Other times, however, they are dangerous and serious antagonists/villains that deploy very sneaky tactics, random plans of chaos and deceptive techniques to fool other people, their foes and/or the heroes. Pulling tricks onto anyone is their expertise.
