King Pig

The King Pig a.k.a (The King) was the main antagonist of the Angry Birds series of games, and serves as the leader of the Bad Piggies. His grand scheme is using his minions to capture three unhatched eggs from the Birds to use as food. While he does succeed on most occasions, the Birds are able to destroy his army and retrieve the eggs, while badly injuring the King Pig.

Trivia

 * In Angry Birds Space, King Pig now supports the idea of Boss Battles which is similar to the same setup in the game of, Angry Birds Rio where Maruo, the leader of the Marmosets appears on level 8-15 as a boss battle and Nigel, appears on level 2-15 and 12-15. The two major boss battles in which King Pig stars in so far until more updates in Angry Birds Space appear is on level 1-30 as a UFO tank and as a UFO Spaceship on level 2-30 where as in other Angry Birds Games (except Angry Birds Rio) he is located in a Castle-Like Fortress along with the other pigs that surround his Fortress.
 * As there is only one King Pig in the entire game, it's the most rare variety of Pigs seen, and when it does appear, no more than one King Pig will ever appear in the same stage together. The only exception is Golden Egg Level 13, which features four King Pigs, but isn't considered part of the official Angry Birds canon due to the stage being a bonus level.
 * For some reason, the cardboard King Pig can move, and do things such as laugh, smile, and blink. However, the King Pig may have designed it like that to heighten the illusion that it was real. It's also possible that the King Pig placed the cardboard cutout and escaped just before his defeat.
 * The King Pig is the only pig to have two ears on one side, rather than one on either side of its head. In Angry Birds (Google Chrome), all pigs share this trait due to their redesign.
 * In 4 Angry Birds board games, Knock on Wood, On Thin Ice Catapult Deluxe Set, and Spring Is In The Air, the King Pig's crown is removed and replaced by one of his ears.
 * In Mine and Dine, he appears in the final level of each world. In Mighty Hoax, if his cardboard cutout is considered real, he appears in the final level for both worlds.
 * In the original game, he does not appear in Mighty Hoax (all the pigs are Cardboard Cutouts) or Birdday Party.
 * In Angry Birds (Google Chrome), in the SD Version, the King Pig only makes the deep "hul", and "ul" sounds along with the Mustache Pig, however this does not happen in the HD Version.
 * In the comics, where the pigs have their own side of the story, the Pig King is occasionally a sympathetic antagonist.
 * The Moon Festival comic shows also that despite his greed and arrogance, the King cares for the other pigs. When he is separated from them when he goes to the moon, he is told by the Yellow Bird about how the Birds, despite bickering on occasion, still get along, because they are family, and at this the King begins to cry, missing the other pigs back home.
 * Ironically, the King Pig has a three-pointed crown, for as a three-pointed crown is used only for a Queen.
