Okay, so here it goes, at the end of a long and tiring journey, unparalleled amounts of hype and maybe a few dragons or minor villains, the hero finally gets his chance at fighting the Big Bad, the character everyone has been waiting to see in action since the tale began. He's mean, he's evil and he's ready to kick the ass of everything within a two mile radius and...
He's been beaten. Just like that. Surely there has to be a mistake. This can't be the evil so-and-so everyone was writhing in their seats waiting for? Surely this guy is an impostor or isn't really dead! However, as the credits begin to roll, it finally hits you: the badass is dead and it's all over.
Ladies and Gents, the badass has just Pulled a Venom. When a character who is popular, foreshadowed or continuously hyped (either by other characters or by fans) appears extremely late into the story and exits faster than the blink of an eye, either being defeated anti-climatically or killed, in a manner which leaves NO room for him/her to return. This is usually used as a means of wrapping a story up in an alloted time whilst still appeasing fans, to create an impact on the audience or for comedic effect however, it can also be a method of an author or writer eliminating a character they dislike or due to incompetence.

needs a more detailed opener, perhaps and examples. Also, do we have this one yet?
