King Pig

The King Pig (also spelt as Pig King and just The King) is the main antagonist of the Angry Birds series of games, and serves as the leader of the Pigs. His grand scheme is using his minions to capture three unhatched eggs from the Birds so that they may satisfy their hunger. While he does succeed on most occasions, the Birds are able to destroy his army and retrieve the eggs, while seriously injuring the King. When he recovers, he once again swipes the Bird's eggs using a different method each time. In some cases, he will distract the Birds with a cardboard cutout of himself (in Mighty Hoax), or enslave multiple Birds, as he does with the Boomerang Birds in Danger Above and almost the entire Bird tribe in The Big Setup in order to prevent his schemes from being foiled, but in the end, all the Birds end up succeeding.

Trivia

 * As there is only one King Pig in the entire game, it is 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 is not considered part of the official Angry Birds canon due to the stage being a bonus level.
