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

Silver is a character that appears in the Angry Birds series. She is a bird and Chuck's sister.

Concept and creation
During the 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 square bird 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.

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

Past
In the past, Silver was born and raised as part of Chuck's family. Initially, she was seen as a "weirdo" by her relatives, though her incredible intellect and achievements at a young age made the rest of the family start to respect and appreciate her.

The Angry Birds Movie 2
Chuck and Bomb ask Red to speed date, where he meets Silver but she deems him incompatible. Red quits the meeting and finds Leonard, the king of Piggy Island, comes to his house to negotiate. Later, Red, Chuck, Bomb and co. visit Avian Academy to find the brains of the group and ends up finding Silver, who is revealed to be Chuck's twin sister and is creating the Super String, a fiber with a very high tensile strength. Red reluctantly agrees to build an alliance with the pigs and they recruit Chuck, Bomb, Silver and Mighty Eagle. They hold a special meeting in Mighty Eagle’s cave. When Red shows a photo of Zeta, Mighty Eagle behaves abnormally. The meeting is disrupted when Zeta's ice ball hits Eagle Mountain and destroys it, but they escape just in time.

Later on, the team travels to Eagle Island via submarine. Once there, Mighty Eagle reveals that Zeta is his ex-fiancée that he abandoned due to his cowardice, retreating to Bird Island. Red insists on fighting alone and Silver decides to follow him. They intrude the base from the mouth of the weapon only to be captured by the her guards. The other team members disguise themselves as Harvey, grab a key card from a staff member in a washroom, and get into the base. The guards are driven into a breakdance battle by the disguise's unusual movement, and the team find that Red and Silver were being caught. They are forced to escape when their disguise rips apart, but the guards are too busy dancing to notice.

Zeta tells Red and Silver her plan to fire lava balls at Bird Island and Piggy Island, while the former regrets telling the islanders to not evacuate. After she leaves to start the countdown, Red admits to Silver that he put himself before anyone else as he's afraid of not being liked if he's no longer a hero. Silver frees them both using her Super String hair braids, reuniting with the team. Red transfers the leadership to Silver, who establishes a plan to destroy the weapon.

Silver and Red put themselves in an ice ball and roll towards Zeta's superweapon, but it misses the target, and the whole team are confronted by Zeta and her guards. At the same time, Mighty Eagle arrives to apologize to Zeta, but she quarrels with him, revealing his name as Ethan and that she gave birth to a chick he was unaware of named Debbie. While Zeta is distracted, Silver tells Chuck to tie up the weapon using a powerful rope she invented, which catches and decelerates the lava balls when Zeta fires them. As the rope breaks, the hatchlings and the piglets traveling above Eagle Island help grasp it. The lava balls slide back into the weapon, destroying the base.

Everyone escapes the base, and Mighty Eagle protects Debbie from being crushed by a metal plate. Zeta shows gratitude to him and they finally hold a wedding ceremony on Bird Island, with Red as the chief witness. Everyone cheers Red for saving the islands, but he reveals Silver and the team deserves the real credit instead of him, unveiling a Mount Rushmore-style monument to them. To his surprise, Red finds he is beloved even more now because of his honesty and selflessness. The birds have a huge party to celebrate while Red and Silver begin a romantic relationship, until Chuck arrives and interrupts the two.

Angry Birds 2
Silver is first introduced in Angry Birds 2. Originally, she was unlocked in level 24 of the game, in New Pork City, though in later updates, she can now be unlocked after completing a level with a Bird key. Silver can be upgraded with gray feathers to give the player extra points.

In gameplay, Silver can be playable any time the player has a card of her in their hands. While not very powerful, Silver can destroy stone with no problems. When tapped onto the screen when launched, Silver will loop forward and up in a circle to fall downwards. When she impacts with an object, shw will slightly push objects away. In addition, with this ability, Silver will be able to hit bosses with an incredible strength. While she cannot be used if the player does not have a card of her, they can play as her again after they obtain, by random chance, a card of her by filling the Destructometer.

Angry Birds on The Run
In season one of Angry Birds on The Run, Silver appeared on various posters in the girl's room.

Powers and abilities
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.

Aside from her intelligence, Silver is very athletic and acrobatic. 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. To add to this, she is quite strong, being able to destroy stone, though in a limited number.

Windblade
By being exposed to the radiation of an extraterrestrial device, Silver can turn into Windblade. In this state, she gains a robotical 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.

Elita-One
By being exposed to the radiation of an extraterrestrial device, Silver can turn into Elita-One. In this state, she gains a robotical look similar to Windblade's. Being an Autobird, she can change her form to turn into a small ship or a person, and can also shoot missiles that can destroy obstacles. This transformation only appeared in Angry Birds Transformers.
