The Bad Piggies (or simply "The Pigs") are the main antagonists of Angry Birds. They seek to steal the Angry Birds. To prevent the birds from reclaiming their eggs, they construct buildings and other structures. The Pigs reappear in Angry Birds Rio as balloons.
They are all green in color and come in different variants: small, medium, and large and sometimes wear different accessories and hats.
- King Pig
- Moustache Pig
- Helmet Pig
- Chef PIg
- Minion Pigs
Throughout the levels of Angry Birds, the pigs can be seen standing on or near obstacles which the player must knock down by launching the Angry Birds from a slingshot. Depending on the impact of the launched bird, the pig may show signs of injury (such as a black eye) if the impact wasn't strong enough. If the impact was strong enough, the pig would vanish into smoke, indicating its defeat. The next level begins once all the visible pigs are killed by the knocked over obstacles.
Other than plotting and stealing eggs, they do not seem to do much else. They do not pose as much of a threat as they do not fight back when under attack. In fact, in Angry Birds Toons they are shown to be rather incompetent. In the cartoon, they also always ended up overpowered every moment they attempt to fought back. The King Pig in cartoon depicted as overweight, chubby pig with slighty different crown unlike his game counterpart, whom body is round like other pig.
