Silver

"Guys. This is Silver, the greatest kid sister in the world." "Well, I'm not exactly a kid anymore, Chuck." "Oh... You'll always be my kid sister!"

- Silver and Chuck, The Angry Birds Movie 2

is a bird that appears in the Angry Birds series. Her role in the franchise can alter based on a specific project, like she could be raised by the Pigs or she is Chuck's sister.

Concept and creation
During production of The Angry Birds Movie 2, the film artists were given the original look of Silver and decided to make drastic, significant changes to her design so that she would look almost completely different because they were aiming for a "cuter" look. She was originally going to be a vulnerable character with a more limited role, but was changed into a very important one in the final cut.

After the design for Silver was finalized, character artist Francesca Natale once thought up of the idea of having her being able to fly by spinning her crest and tail like helicopter blades, which was ultimately scrapped.

Appearance
In her original design, Silver is a Peale's falcon who is mostly covered in gray feathers. Her eyes have black pupils, and her beak has a red-colored end pointing downwards. Her head has long feathers pointing behind her body. She has two teeth in her mouth, with round ends.

In The Angry Birds Movie 2, Silver has a completely different design. She now sports a lighter plumage and aqua green pupils. On both sides of her head, there are two large horsetails. She is also very tall, with thin, yellow, scaly legs. In Angry Birds Journey and Angry Birds Reloaded, this design was altered to take out Silver's limbs, although the former's design would look more like a hybrid of the classic and movie designs.

In Angry Birds Bubble Trouble, Silver's design was switched back to her design from Angry Birds 2, though she now has limbs.

Personality
In the games, Weirdly, Silver was raised by pigs and doesn't even care about the eggs! But even though she's still got some pig-like ways, she's happier with the flock and is a great flyer who is very funny. Silver was initially a stolen egg by the pigs, who were just about to cook the egg until it had cracked open. Thus, Silver was born, and the pigs took her in as their own. Because of this, Silver notably has multiple physical and mental traits of the pigs, having a very goofy sense of humor and even having the same exact teeth as the pigs.

However, after the release of The Angry Birds Movie 2, Silver's origin and personality was completely changed. Now she is portrayed as Chuck's sister as well as being Red's love interest. It also introduced the idea that Silver was very intelligent, something that would carry over within appearances like Bubble Trouble or Reloaded.

Powers

 * Looping Legend - One of her main movements involves looping in the air and falling down, which she can use to crash onto a surface and destroy it. She can also use this move to send nearby objects flying away.
 * Transfomations - By being exposed to the radiation of the EggSpark, Silver was turned into both Windblade and Elita One (see details about their abilities above). In this state, she gains a robotic look. As an Autobird, she can change her form to turn into a small ship or a person. She can also shoot missiles that can destroy obstacles. This transformation only appeared in Angry Birds Transformers.
 * Star Pop - Only appears in Angry Birds POP!

Abillities

 * Intelligence - Silver is very intelligent and has crafted a variety of inventions, with one of them being superstring, which she readily has on hand to use as a grapple. She can also perform a huge number of calculations on the fly to anticipate what is happening in very tense, action-packed situations then uses them to immediately come up with and take the best action possible.
 * Skilled Acrobat - Silver has been shown to be a skilled acrobatic as she is seen doing some when leaping out of Bomb.

Weaknesses

 * Strength - While Silver is quite strong, she is able to destroy stone, but only in a limited number.
