 * Angry Birds

 * Angry Birds Rio
 * Angry Birds (Google Chrome)
 * Angry Birds Friends

Release History
Mighty was first made available in the Angry Birds episode "Ham 'Em High", launched in December 2010. It was subsequently released for Angry Birds Seasons on August 22nd, 2011 with a bug issue and was fixed on August 23rd, 2011, Angry Birds Rio on October 28, 2011, Angry Birds (Google Chrome) on December 1, 2011 and was included with the launch of Angry Birds Friends on February 14, 2012.

Description
Mighty is stronger of all of the available Birds, and as such, has a limited use: If the Eagle is used on a level that hasn't been completed normally, it can't be used again on another non-completed level until a solid hour has passed. However, if the Eagle is used on a level that the player has already completed, the player won't have to wait before it can be used again.

Gameplay
 To summon the bird, the player must first purchase him (only once), then on the top left of the screen during gameplay, press the same eye button used to first purchase the Eagle. If this button is tapped, all of the standard Birds will instantly disintegrate and a can of sardines will land on the slingshot. Then, the player must simply fire the sardines at the Pigs' structure. After a few seconds, Mighty will come roaring down from the skies and strike the ground with incredible force, killing all pigs and piercing through any blocks he launched through. Any missed pigs will be instead killed by a massive earthquake the Eagle causes. Also Mighty has a unique ability-- if you place the can of sardines in front of the pigs structure, it will in turn cause him to hit the ground and spin out of control, which actually causes more damage.

If Mighty is used to pass the level, no stars will be awarded.. Instead, the standard scoring system will be replaced by a "Destruction" meter. Depending on how much damage the Eagle causes to the Pig's structure, this meter will fill up to a maximum of 100%. Scoring a perfect percentage ratio will award the "Total Destruction" feather next to the level's icon on the stage select screen. In some scenarios, the default birds will have to be used in conjunction with the Eagle to get 100%. If he is used in an incomplete level, the user cannot use the Eagle in this manner again until he either waits one real-time hour or completes the level again only without using the Eagle.

Mighty's Story
In the animated short film, Red, Chuck and Blue Bird happily stare at some newly-laid eggs. Then, a butterfly accidentally knocks over an egg, angering the birds, thus distracting them. The pigs took the opportunity to steal the eggs.

After going after the pigs to defend their eggs, in the process destrying several small pig forts, the pigs were eventually forced to retreat into a large steel fortified base invulnerable to the bird's effort.

Suddenly, Chuck pulled out a can of sardines as an idea to get help from Mighty. Then, Red, in fear, went to the cave where Mighty dwells, and asked for assistance while offering the sardines.

A chef pig came out of the base later on, scouting. He was suddenly knocked on the head by the sardine can. He looked around, saw the can of sardines, and the shadow of said eagle appears. The chef panics, squeals, runs inside, chucks the eggs out of the fortress, and waves a white flag, indicating a surrender. Unfortunately for him, he gets crushed by the eagle anyway. The eggs are finally safe. In the end of the video (Angry Birds and the Mighty Eagle), Mighty is closer to the camera making the noise of his approach and the scary music

Trivia

 * Mighty has been mentioned in the Angry Birds Peace Song.
 * In the Ham'o'ween animated backstory video, The Blues (dressed as Frankenstein, the devil, and a witch) trick or treat at Mighty's cave and he gives them candy.
 * In a previous installment of Angry Birds Seasons, titled Year of the Dragon, Mighty is replaced with the Mighty Dragon, which works the same way.
 * Mighty sounds like Terence when he destroys something.
 * Mighty has visited Santa's workshop according to the Christmas comic.
 * The Blues in the comics have mentioned Mighty having multiple places of residence, of "rejuvenation spots". The primary appears to be high atop a cliff, as depicted in Ham'o'ween and the comics.
 * Mighty is the eldest, strongest, and wisest of all the birds. He was likely feared by the Angry Birds originally, since Red was very afraid to go ask him for assistance in the Mighty Eagle trailer. As seen in a wallpaper, even Terence is afraid of Mighty. But as time progressed, especially in the comics, the Birds began to be less afraid of the Mighty now. In fact, the Birds not only go to him to help them stop the pigs, but in the comics, they go to Mighty for advice and listen stories that have took place a long time ago.
 * Another time when the Birds weren't afraid of Mighty was in the Ham 'O' Ween Animation, where the The Blues visited his cave during Trick or Treating and Mighty gave them candy.
 * In the christmas comic, when Mighty visits santa's workshop, the purple ring around his eyes are gone.
 * In the Year of the Dragon animation descriptions and shop descriptions, it is said that Mighty transformed into Mighty Dragon, but in the comic, it is said Mighty was an old friend of Mighty Dragon and Mighty Dragon was accepted to look after his rejuvination spot while Mighty is gone.
 * It seems that Mighty has a lot of different counterparts, such as Mighty Dragon, the Space Eagles from Angry Birds Space, and the Mighty Philadelphia Eagle.
