Fat Pig

Big Bork combs the Universe looking for cosmic food to continually increase his size. He is massive with spots on him similar to the Big Brother Bird. The description of Big Bork according to The Daily is: "As ravenous as he is disgusting". Big Bork is first seen incased in a large planet of ice in Cold Cuts. He then breaks free from the planet and moves to Utopia to satisfy his stomach.

His first appearance in game is in level 4-10 (Utopia) as a regular character. He is smaller than he is in 2-20. Despite his extreme size, he is easily popped. On the Angry Birds Facebook Page, a picture shows that Big Bork has grown more larger because of it eating more Utopian food. Another thing to note about B ig  Bork is that he resembles the original/old designs of the Bad Piggies than the Angry Birds Google Chrome design.

Boss Strategy
The Big Burp, which is the Big Bork boss from the beginning cutscene, awaits the player on level 4-30, in which he is enormous and serves as a boss. Like its fellow pigs on Earth, the Big Burp is also unintelligent, as it eats everything in sight, allowing hazardous objects to easily harm it.

The player must wait until the Big Burp rotates so that the desired hazards can enter its mouth. The player can either knock asteroids into its mouth, feed it burnt popcorn by hitting the popcorn generators, or even hit the Big Burp with the Birds themselves. However, only Black Bird and Terence will do any noticeable damage. Continuously feed the Big Burp hazards until it coughs up an eggstroid, which cannot be obtained.

In the ending cutscene for Utopia, it was revealed that the Big Burp had consumed the eggsteroid belonging to the Ice Bird. Coughing up the eggsteroid reduced his size to a mere Large Pig with spots.

The Big Burp is one the three bosses who have achievements named after the respective bosses, along with Handy Man and Sub Pig.

Angry Birds Toons

Trivia

 * Big Bork seems to drastically reduce size when he is beaten. In Angry Birds Space, once the Space Flock defeats him he turns into a regular-sized pig. In Angry Birds Toons, he turns into a smaller version of El Porkador when beaten by Terence.
