Villain Opening Scene

A Villain Opening Scene begins the story with the villain. As it's an Establishing Character Moment, often the villain's first act will be a Kick the Dog or Moral Event Horizon crossing moment that serves to show how evil or Badass he is, and often sets up the situation that the hero then has to resolve.

Common in stories in which the villain and the plot are essentially synonymous.

Anime and Manga

 * The first scene of Magical Girl Lyrical Nanoha As involves Hayate and her Book of Darkness, though villain is used in the loosest sense of the word here.
 * A lot of Detective Conan stories open this way as well.
 * The first episode of Dragonball Z opens with Raditz landing on Earth and killing a farmer.
 * In the North American version of Kirby Right Back At Ya, the very first episode opens with an immense, evil crimson octopus Demon Beast/monster called Octacon attacking and eating a whole flock of sheep to a Cappy farmer's horror before flying back to King Dedede's castle. This scene actually switched places with the original Japanese opening scene where Kirby is flying through space asleep and eventually comes into orbit over Popstar in the dub.
 * Also, the episode "Masher 2.0" begins with Knuckle Joe in a battle against a newly-rebuilt Masher 2.0. And not doing too well against it. At least he does well against its helpers, some of Nightmare's kaiju-esque monsters seen in Meta Knight's flashbacks.
 * The tenth One Piece movie opens with hero antagonists Garp and Sengoku looking on grimly and expositing as movie Big Bad "Golden Lion" Shiki worfs an entire Buster Call-sized fleet of Navy battleships.
 * Arashi no Yoru ni begins with Giro and his pack of wolves attacking and killing Mei's mother, who tells her son to run away into a nearby forest for his own safety. Just right before she bids her son goodbye and is killed by the wolves, the mother goat attacks Giro and bites off one of his ears.
 * Pokémon: The First Movie begins with Mewtwo destroying the very laboratory he was created in, killing all of the scientists inside, and immediately escaping.

Films -- Animated

 * Mulan opens with Shan-Yu and his army attacking the Great Wall of China. Mulan herself doesn't appear till scene three.
 * For Disney, this trope goes back to the very beginning. The first proper scene of Snow White and The Seven Dwarfs is of the Queen consulting the Magic Mirror.
 * Dinosaur actually begins with the film's Big Bad, the Carnotaurus attacking the nest made by Aladar's mother, smashing all but one of the eggs (which was taken away by an Oviraptor, and later on a Pterodactyl, to Lemur Island) and presumably killing his mother.
 * Tangled begins with the villainess finding the magic flower used by Rapunzel's mother to heal her illness (and later transferring its magic to her daughter's hair), only to have it snatched away by the King to heal his aforementioned wife.

 * Flash Gordon: "Klytus, I'm boooooored."
 * All three original Star Wars films open with a shot of one or more Imperial Star Destroyers (though the Rebel Blockade Runner is seen first in A New Hope). Return of the Jedi most closely fulfills this trope with its first scene featuring Darth Vader.
 * Dirty Harry begins with the first Scorpio murder. More accurately, it starts with a pretty girl taking a swim in a rooftop pool, then zooms out at length until we see the barrel of a sniper rifle...
 * Kung Pow starts with a young Master Pain (before he took on the name Betty) killing The Chosen One's parents.

 * Clash of the Titans opens with a villain, King Acresius of Argos, crossing the Moral Event Horizon by sentencing his daughter and baby grandson Perseus to death by exposure in a sealed boat cast upon the waves.

 * Star Trek the Motion Picture opened with V'Ger and Star Trek V: The Final Frontier opened with Sybok. (The status of both as true "villains" is somewhat debatable, though.)
