Pure Evils which can be funny to the audience in some way; however their actions are still taken completely seriously in-universe, and their humor is often sadistic and only serves to make them even darker, edgier and heinous than they already are. Syndrome, the Joker, Kilgrave, and especially Bill Cipher are prime examples of what can be expected from such villains. In some cases, the villains might not have any real comedic moments at all but they are so over-the top-that it's hard if not impossible to laugh at them (e.g., Dio Brando, Light Yagami and AM), Pure Evils can still seem comedic in-universe as long as they are using it as a façade to get others to like them so they can do something diabolical later on (Aku). Some Pure Evils get away with their crimes with their charisma and the survivors never find out that their comedy was fake, and still laugh at them (unknowingly).

They are the more evil counterpart of Comic Reliefs, since their humorous moments don't lighten the mood of the story, and the complete opposite of Seriously Good.

Some Laughably Evil Pure Evils can be Game Changers as well. To achieve this, the story needs to be a comedy with a Pure Evil who generally darkens the comical mood, but still has funny moments here and there. This can only happen if the villain has a cooling-off period and/or uses black comedy. Agatha Trunchbull, Melisha Tweedy, Dr. Henry Miller and Porky Minch are perfect examples of that, because they are the main reason their story is so dark, yet due to the story's comedic nature, they are so easy to laugh at once they let their guard down and are not a threat for a few seconds.

NOTE: A Pure Evil having one, two, or an overall small number of minor comedic moments is not sufficient to make them Laughably Evil (e.g., Dag, Emperor Belos, Ozai, The Lich, Goku Black, Professor Kindly, Peter Pettigrew, Lots-o'-Huggin' Bear, William Afton, Dropkick, the Skar King and Moff Gideon). A Laughably Evil Pure Evil has to have their comedic moments more prominent, memorable, and in greater abundance.
