Laughably Evil

An laughably evil character is a purely comedic type of villain/antagonist that is evil yet they are downright enjoyable and entertaining as diabolical characters whose antics & shticks are done in the form of comedy/entertainment.

NOTE: This trope should not be confused with a comic-relief villain. These kinds of antagonists range from villains that are taken seriously in the show but still have funny moments like having a sadistic/cruel or witty sense of humor that makes them more heinous and threatening (ex. Hades from Hercules and Shaw from Open Season), to being depicted as ridiculous-looking villains who have committed serious misdeeds despite their goofy and comical presence that makes viewers not take them seriously (ex. Plankton from SpongeBob SquarePants).

Why This Trope Rocks

 * 1) They solely exist for providing tons of amusement value to their continual acts of villainy, and their humorous and comical traits are downright perfect for the entertainment value, sometimes reaching to the point of providing comic relief levels of being fun to watch!
 * 2) They tend to have a strong sense of humor, which brings a level of charm to their nefarious traits while doing both; posing a threat or doing villainous actions while making you laugh at the same time.
 * 3) Even if there are shows where the protagonists aren't the most interesting or funny, these villains can be such a riot that viewers get hyped to see the villains for their hilarious and entertaining antics that can make a show or movie much more exciting and rewatchable (or it makes video games replayable just for them stealing the show).
 * 4) * Likewise, some of these villains' antics can potentially redeem a bad episode or a bad scene from a good episode that took place given the right amount of timing and writing for that episode.
 * 5) Despite most of them being rather laughable, some of them can still be taken seriously given the right amount of balance to their traits between being formidable or humorous.

The Only Bad Quality

 * 1) Even though comedy is subjective, there are viewers that can find these villains' comedic traits rather tiresome, unfunny, poorly written, or forced.
 * 2) * If they're not treated as a threat or have too many humorous moments even though they're meant to be intimidating, this typically makes them fall into Flanderization and/or Character derailment territory of being incompetent shells of their former selves. Especially if making them more "funny" or "ridiculous" was meant to make them lovable when it didn't make them any better and just makes them more of a joke than necessary.
 * 3) The way this trope is used often confuses the rules on how to make villains a genuine threat if they're meant to be threatening.
 * 4) * Because the definitive "Laughably Evil" villain is a villain who is funny in appearance or behavior, but their villainous actions are taken seriously in their universe in comparison to a comic-relief villain, while they can share similar qualities of Laughably Evil villains with their evil or nasty moments, but they are typically meant to be unthreatening and humorous to make the audience laugh in relief (ex. Dr. Weird from Aqua Teen Hunger Force, Professor Monkey-For-A-Head from Earthworm Jim and Robbie Rotten from the LazyTown show).
