Red

"I'm Red! The mighty defender of the nest! The smasher of pigs! The castle-busting wrecking ball!"

- Red, Angry Birds Comics #10

Red J. Bird (born in August ) is the main protagonist of the Angry Birds series. He is a desert cardinal native to Bird Island with a short-tempered and rude personality.

Born an orphan on Bird Island, Red was an anti-social person with rarely any contact with anybody else. After Leonard's attacks on the island however, Red was accepted by the Bird Island society and had many new friends. He currently lives on Piggy Island with some of his closest friends and takes care of the eggs.

Appearance
Red is a desert cardinal with red feathers that cover most of his body, hence his name. On his head, he has two small red feathers with a circular end, and on his tail, there are two short black feathers with square ends. His belly is peach-colored, and he has small, crimson spots ordered in a line across his face. In the Wreck the Halls short in late 2011, he was slightly modified to have him with a more cartoonish look. This design was not used again until Angry Birds Toons in 2013, and has become the most common design since then.

Originally, Red had a spherical body without showing any limbs at all. After the release of The Angry Birds Movie, he received an anthropomorphic, pill-shaped body with his head directly connected to his torso without a neck. His crest and tail feathers are also much longer and detailed than before. In addition, his irises were tinted brown. Future releases would occasionally switch between Red's new body and his old one.

In Angry Birds Dream Blast, Red was re-designed again to resemble a hatchling. In this game, he is much shorter, with a round body and small limbs. Angry Birds Journey uses a similar design for its trailers and promotional artwork, though it was somehow more simplified. In the levels of said game, he uses his design from Angry Birds Toons, though modified to have a small beak and brown irises.

Personality
Red is a short-tempered person. The angriest of all the birds, he is not above using violence when someone annoys him. He is someone who takes his duties very seriously, not willing at all to leave them aside. However, he also likes to discover new things when he is in a day off.

"Hey, Red! How are 'ya?" "Oh! I'm horrible!"

- Early Bird and Red, The Angry Birds Movie

During his earliest years, Red was an antisocial person who was rejected by the rest of people. With an unstable anger (despite him trying to state otherwise), he had always hated being disrespected and made fun of, as he took jokes very seriously. This would result in him getting enraged and/or sad. As he grew up, he was also someone who could get frustrated by anything, acting rude in front of other people not matter who friendly they were towards him. However, after he stopped Leonard from cooking the eggs from Bird Island, Red became much more outgoing and was approved by the rest of the birds, which allowed him to control his anger issues much more than before. Nevertheless, even after these incidents, it was shown that Red could still get angry at anything, sometimes cursing himself for his actions, and showing an open hatred for ridiculous holidays. He himself has admitted that he still suffered from anger issues from time to time. However, he is not ungrateful and appreciates the effort others make for him.

Since he moved to Piggy Island, Red has been very fond of the three eggs he sometime ago found there. As he believes that they will be very important for his species' survival, he takes good care of them and is not willing to leave them alone; once, he was shown spending entire seasons only looking after them. Whenever he is left alone with them, he softly strokes them and tells them bedtime stories, being one of the rare moments where he shows a soft side. Similarly, he spends hours in the morning cleaning and polishing his propierties, specially the slingshot, and constantly checks that its band is perfectly elastic. He easily loses his temper whenever something, such as an insect or a leaf, touches either the eggs or the slingshot. He also returns back to his usual serious self when others come in.

Ever since the first time he met them, Red has had a mutual dislike for the pigs, being skeptical about them during their stay on Bird Island. After he and his friends moved to Piggy Island, his hatred for them was just aggravated. As a result of all the times they tried to steal the eggs, Red has become even more determined to keep the latters safe, which has bordered him on schizophrenia when he is not near them; a notable example of this was shown when, while he was having a forced vacation, Red started to have hallucinations where he saw all surrounding objects as eggs. A similar case was when he had saw everything round as pigs, though this was due to his rage after he defeated a group of pigs. This also made him very paranoid, interpreting small things as a declaration of war, such as imagining the sound of the wind as a battle cry of the pigs. Despite his friends' best attempts of making him forget about them for a while, he never managed to take them out of his mind. He even is enraged by the smallest sight of green due to this.

"Huh? Me? Lonely? Never."

- Red, Angry Birds Comics (2016) #1

While serious and hostile, Red likes being with other people, and appreciates their company. He is afraid of losing his friends and being ignored by others, just like in his childhood and adolescence, though he keeps this fact a secret to everyone. It has been confirmed that Red never managed to get rid of this trauma; a notable example of this was when Chuck asked him if he feared something. While Red said that he was not scared of anything, he had some flashbacks of him being left alone by others. Another example was when his friends were preparing him a surprise party for his birthday. Unaware of this, Red thought that his friends had died during an incident, or that they had abandoned him. However, when he realized that they were completely fine, he was so happy to see them that he shedded a tear. Despite him sometimes treating his friends badly, Red respects and trusts them, and is not above leaving aside his duties to visit them, such as when he wanted to go to Rio de Janeiro to visit Blu and Jewel.

Angry Birds (game)
In the original Angry Birds, and its Chinese version, Red appears as one of the main playable characters, first making his appearance in the very first level of Poached Eggs, or the first level of Tutorial in the newest versions. He would later appear in every other episode as a playable character, except in The Big Setup. In the levels and most cutscenes, he appears in his first design, though the card of Tutorial, the shop, the profiles of The Mighty League, and the cutscenes of Piggy Farm and Jurassic Pork have him in his design from Angry Birds Toons.

In gameplay, Red is a common bird used mostly to weaken buildings due to him being rather weak, losing his momentum instantly when he destroys glass. However, the Power Potion and the King Sling power-ups can make him stronger. When tapping onto the screen when Red is launched, he will scream, but this will not do anything. Each Red the player does not use to complete the levels will award them with a bonus of 10.000 points.

In Red's Mighty Feathers, and some of the levels of Flock Favorites and Golden Eggs, Red was transformed after being surroundered by some of the Mighty Eagle's feathers. When tapping anywhere onto the screen when this Red is launched, he will head towards said direction until he crashes onto something. Nonetheless, he is still as weak as in his normal state. This version of Red also appears as the only playable character in the Egg Defender minigame, in an unlimited number. Here, the player will hav to use the least amount of Reds as possible to destroy the pigs' vehicles and prevent them from stealing the egg. Unlike other episodes, the player cannot use power-ups on Red due to them being disabled in the minigame.

Angry Birds Seasons
In Angry Birds Seasons, and its Chinese version, Red is a playable character first introduced in the first level of Trick or Treat, or the first level of Hammier Things in the most recent versions of the international version. While the levels and the level selection screens until South Hamerica have him in his design from the original Angry Birds, the level selection screens from Power-Up Test Site, Ham Dunk, Tropigal Paradise, and Fairy Hogmother have him in his design from Angry Birds Toons; while, in the level selection screens from Marie Hamtoinette and Piggywood Studios, he is seen in his design from The Angry Birds Movie. In addition, in the international version of the game, since October 2015, Red can be given optional Bird Hats to wear in the levels, though these are entirely cosmetics.

In gameplay, Red has the same strength as in the original Angry Birds, and, like in said game, can be powered up with the Power Potion. He also appears as the powerup Homing Bird, and the Powerbird Telebird. Each Red the player does not use to complete the levels will award them with a bonus of 10.000 points.

Angry Birds Rio
In the "Rio" storyline of Angry Birds Rio, Red and the other birds were all kidnapped and sent to a lair in Rio de Janeiro, Brazil. The being responsible of the kidnapping, an anthropomorphic cookatoo named Nigel, showed up and revealed that he had kidnapped Red and his flock to sell them in exchange of one hundred thousand dollards, due to them being part of an "exceptionally rare species". Seeing many other birds trapped in the lair as well, Red and his comrades broke free and liberated the caged birds, including two macaws named Blu and Jewel, who were united by handcuffs. Red and his friends, alongside Blu and Jewel, escaped to a jungle as Nigel sent his marmosets to go after them.

After venturing through the jungle and defeating the marmosets and Nigel himself, Red and his group met Rafael, a friend of Blu, who guided them to a beach where they could find Luiz, a bulldog who could take the handcuffs out of Blu and Jewel. After going to the beach, they found the bulldog, who managed to separate the macaws from each other. However, Jewel was soon after caught by Nigel.

That night, Red and his flock ended up in the middle of a carnival, where they defeated Mauro, the leader of the marmosets, and found Jewel, alongside many other kidnapped birds, hidden in a chicken-like vehicle. Just as Blu was about to free his friend, he was caught by Nigel, who escaped with him and the other birds as Red and his friends went after them. Ending up at an airplane, the birds managed to get aboard one plane that had Blu, Jewel and Nigel. After freeing the other birds, Red and his comrades had a final showdown against Nigel. When the cookatoo was defeated, he tried to escape, only to be caught by one of the plane's propellers, damaging it. Despite the odds, Red and his flock managed to control the plane and crash-land on Piggy Island, right before Foreman Pig and Minion Pig stole their eggs.

In the "Rio 2" storyline, Red and his friends received a postcard from Blu and Jewel, inviting them to go to Rio de Janeiro to visit them. Accepting the invitation, the birds put themselves inside a wooden box that was supposed to be sent to the city. However, they were sent to many different locations throughout the world, and even ended up on the Moon, much for Red's wrath. From there, they entered the earth's atmosphere and landed at the outsides of Rio as they watched the a firework display, for their pleasure. However, they were soon after forced to deal with the remaining hordes of marmosets. Eventually ending up in a harbor, Red and his comrades freed some birds and dolphins, before committing the error of freeing Nigel himself, who had somehow survived the past incident. Later, on a lake, Red and his flock managed to throw Nigel to the waters. They and Blu later dealt with the remaining marmosets.

In gameplay, Red has the same strength as in past games, though he can be even stronger with the Power Potion. In the "Rio" segment, he uses his design from the original Angry Birds, while the "Rio 2" episodes have him in his design from Angry Birds Toons. He is first used in the first level of Smuggler's Den, or in the first level of Playground in the newer versions. When tapping onto the screen when Red is launched, he will scream, but this will not do anything. Each Red the player does not use to complete the levels will award them with a bonus of 10.000 points.

In addition, Red is featured as the powerup Samba Burst. Here, he will be wearing a fruit hat, and will have a happy expression. When he collides onto any surface, he will make all the surrounding objects shake and launch them.

Angry Birds Space
In Angry Birds Space, Red appears as Super Red. At the start of the events of the game, he and his friends were taking care of their eggs as usual, until they spotted a wormhole in the sky and, from it, Ice Bird and an eggsteroid. Eventually, they saw a large metallic claw fall from the wormhole, which grabbed a chunk of soil with the eggsteroid and the left with it. Furious, Ice Bird used the group's slingshot to enter the wormhole. While Red and his friends initially did not care about this, they soon after found out that their eggs were stoen as well. Enraged, they used the slingshot to enter the wormhole as well. They soon after found themselves in space, with new transformations, stopping King Pig from stealing the eggsteroids.

Angry Birds Friends
In Angry Birds Friends, Red appears as a playable character. He has the same strength as in past games.

Bad Piggies

At first, he will be sleeping, though he can be woken up with the the noise of the player's vehicle. If the camera is not showing Red, an icon showing his location and if he is about to be woken up will appear. When Red is awake, he will try to detect the player's presence. If he succeeds, he will jump onto the slingshot and launch himself towards the player's vehicle. Red is be quite strong, and can damage fragile vehicles, unless they use the Super Glue.

Angry Birds Epic
"Protects the party. A real hero!"

- Description, Angry Birds Epic

In Angry Birds Epic, Red appears as the main default character. At the start of the events of the game, he and Chuck were minding their business as usual, until they were attacked by hordes of Minion Pigs led by Wizpig and Prince Porky. The pigs managed to defeat the birds in no effort, stole their eggs and their personal equipment, and kidnapped Chuck. Furious, Red ventured through the South Beach and rescued his yellow friend. At the Cobalt Plateaus, they got one egg and found Matilda crying because her garden was destroyed by Porky. The white bird soon after joined their group. The flock then chased Porky through the Golden Fields, until the pig used his air balloon to escape to Desert Island, which supposed a problem for the flock as they could not cross the Limestone Lagoon that separated Pig Island and Desert Island. Fortunately, Bomb came in with his Bird Ship, only for him to be attacked by a Pirate, who stole the ship's rudder. After retrieving the rudder and rescuing Jake, Jay and Jim, who had been surrounded by the prince and some troops, Red and his comrades managed to retrieve the second egg on the castle.

Later, the flock passed through the Pirate Coast, the Slingshot Woods and the Great Cliffs, before going to the Star Reef to rescue the third egg. Back at the Great Cliffs, Red, Chuck and Bomb were fooled by the pigs and kidnapped. While Chuck and Bomb were fred, the cage Red was in was taken to the sky by Prince Porky's airship. However, the other birds, with the help of Professor Pig, managed to build their own Airship and rescue the red bird. At the Snowy Peak, they got the fourth egg and ventured through the Islands in the Sky, the Pumpkin Plateau, and the Square Forest.

Right outside of the entrance of Pig City, where the fifth and final egg was, Red and his flock found themselves unable to continue with their adventure due to the walls and catapults blocking their way though. By Professor Pig's advice however, they went to the Moorlands and got a Submarine, which they used to pass through a mine field and enter the city. There, they had a duel against Wizpig. Later, they broke through the castle and got the fifth egg.

In a sudden turn of events, Wizpig revealed his true colors to the others and used his magic to get the egg and King Pig's crown before going to the Hog Head Mountain and make himself a Magic Shield to protect himself there. The flock followed him and managed to destroy the shield by defeating the enemies that protected it. Red and his comrades had a definitive showdown against Wizpig, who was aided by Lefty and Righty. However, the pig was defeated. With his last strengths, Wizpig used his own magic to transform into Demonic Wizpig, a state so powerful that no bird could defeat him. However, with the help of Prince Porky, who gave Demonic Wizpig the final strike, the flock got the fifth egg and King Pig's crown. The group then went back to Pig City and gave the king his crown, with him thanking them.

In gameplay, Red's statistics in Angry Birds Epic are as follows:

Angry Birds POP!
In Angry Birds POP!, Red appears as a permanent character. Initially, when the game was called Angry Birds Stella POP!, he was a limited character who could only be used during an event.

In gameplay, Red appears in the "Drop the Pigs" and "Defeat King Pig" levels, though he can be optionally replaced with a Guest Star. When the Bird Gauge is full, he will be able to use the Rock Pop, where he will be able to pop a short line of bubbles.

Angry Birds Fight!
In Angry Birds Fight!, Red was the first out of six playable characters the player could choose to use. Other than being a playable character, he also appeared as an icon in the matching board. Like all of the other birds in the game, Red was customizable to the player's preference, and the player would be able to purchase costumes and weapons for Red with in-game currency.

In gameplay, the player could not play directly as Red; rather, they had to make him attack his enemy by till-matching various small birds. Matching three birds would have popped them out, and matching four or more would activate the specific bird's special ability. If four of Red's icons were matched, then random panels would be blocked out with wooden boxes on the opponent player's matching board.

Once the round was over, the two battling players began fighting, and the player's success would entirely be based on how many points they were able to gather.

In gameplay, Red can be used in any level as long as the player has a card of his. When tapping onto the screen when he is launched, he will make a small scream that will produce a short, red line. If a building is caught by that line, it will be pushed to the other side. This ability works better in tall, unstable buildings, and will not have much effect in structures that are well held. While Red can normally be used only once, filling the Destructometer can give the player a card with Red, allowing them to use him again. The amount of points Red can gather depends on his Bird Power, which can be leveled up by giving him enough feathers, upgrading the slingshot, etc.

However, if he is touched by other bird, or is not used by the player when they complete the level, he will split into two and will run either horizontally or vertically. This means that, for example, vertically, one Red will be running towards the top part of the screen, while the other one will run to the bottom part.

Angry Birds Dream Blast
In Angry Birds Dream Blast, Red appears as a supporting character. This is also the first time in the Angry Birds series where he uses a new design that does not come from past games or media; instead, he now looks like a hatchling.

He can also be added as an optional character in the Level Builder mode. In this game, he has his sound effects from Angry Birds 2, which are taken from some episodes of Angry Birds Toons.

Powers and abilities
Despite not having undergone any notable training, Red is a very skilled and powerful fighter, having been able to break though Pig City on his own many times with no wounds or scratches. His strength is one of his most notable abilities; though most of the time he cannot break stone blocks, Red is strong enough to pick up and launch pigs with ease, and has even been capable of breaking though many different walls and a metal wall within a few seconds with no additional equipment. In addition, his speed has let him run though entire mountains and onto water with no problems.

Red has demonstrated to have a great durability and resistance against attacks. He has been able to survive massive explosions and falls from high heights, and even withstood atmospheric entry once.

Strength and speed aside, Red is able to hide all his limbs to turn himself into a ball, though this ability has only been used once.

Super Red
By passing though an extraterrestrial wormhole of some kind, Red can transform into Super Red. In this state, Red has some different body features, the most notable of which is his black and white glasses, which he can use to track and analyze enemies. However, most of his abilities remain the same. This transformation first appeared in Angry Birds Space.

Unnamed Angry Birds transformation
By using a few of the Mighty Eagle's feathers, Red can have a, so far, unnamed transformation. He looks the same as his normal counterpart, except that he is now surrounded by a few white and red feathers. In this state, Red can head himself towards any location he wants to. However, he can only use this ability once before losing the feathers. This transformation only appeared in the original Angry Birds and its Chinese version.

Telebird
Through unknown means, Red can transform into the Telebird. In this state, he now wears a magenta and yellow helmet on his head. As the Telebird, Red now can teleport himself and surrounding objects to any place he wants to, allowing him to pass through solid objects. However, he can only use this ability once. This transformation only appeared in the international version of Angry Birds Seasons.

Homing Bird
By unknown means, Red can transform into the Homing Bird, where he wears a gray radar on his head. In this state, Red automatically heads himself towards any pig that is near him. However, he can only use this ability once. This transformation only appeared in Angry Birds Seasons and its Chinese version.

Weaknesses
While not having any physical weaknesses, it is confirmed that Red is allergic to pollen. In addition, he can be scared quite easily by a scarecrow, and will be unable to do anything whenever he finds one. Also, he can be distracted whenever he is trying to aim with the slingshot, being scared by other birds' sounds, and even his own farts.

Chuck
Red's best friend is Chuck. The two first met when they assisted Matilda's anger management classes. While Red was initially annoyed by the yellow bird's quick-paced personality, which often made him feel uncomfortable, they quickly became friends. Though Red can still be annoyed by Chuck's arrogant personality, he acts as a parental figure towards him and respects and trusts him. In addition, when Chuck was seemingly crushed by the slingshot, Red regretted his friend's "loss", only to immediately afterwards find out that he was indeed alive and perfectly fine, confusing him.

Bomb
Other of Red's friends is Bomb. The two first met when they were forced to assist Matilda's anger management classes. While they did not get along very well at first, they quickly became friends as they investigated about Leonard and the pigs' hostage on Bird Island. Red acts as a parental figure towards Bomb and respects and trusts him, though he can be annoyed by his stupidity.

Jay, Jake and Jim
Red is good friends with Jay, Jake and Jim. Before the Blues were born, Red saved the egg containing them from the claws of Leonard and his minions. Despite the brothers' irresponsibility and disobedience, Red still tolerates them and acts as a parental figure towards them. Also, whenever the triplets save the eggs from the pigs, Red likes spending a while playing with them as a reward.

Terence
"And this is Terence!" "..." "More like 'Terrifying'."

- Matilda, Terence and Red, The Angry Birds Movie

Terence is a close friend of Red. They first met when they were forced by law to attend Matilda's anger management classes, though they did not get along at first, as Red feared Terence, even calling him "Terrifying" the first time he saw him. However, after Leonard stole the eggs from Bird Island, Terence and the other birds cooperated with Red to get the eggs back. Since then, Terence and Red started to have a better relationship with each other.

Silver
"So, I'm curious. Why didn't we just team up with Chuck? He is definitely faster than me." "No. he is too laid." "Why not Bomb then? You know, he is heavier than me." "Just no. You're perfect." "Oh. That's funny. I though we weren't... compatible."

- Red and Silver, The Angry Birds Movie 2

Silver is another of Red's friends. She was introduced to him by Chuck, though they had a rather tense relationship, as Silver did not trust the red bird. As time passed however, they started to get along. Currently, they are good friends, and have a mutual respect towards each other.

Leonard
"Look, Red, I know we've had our differences..." "Oh, like when you tried to eat our young?!"

- Leonard and Red, The Angry Birds Movie 2

Perhaps Red's first enemy was Leonard. The two first met when Leonard and the other pigs went to Bird Island. Despite the pigs acting friendly towards the birds, Red was skeptical about Leonard, insulting him many times and even making paintings about him dying in multiple ways. It soon after turned out that Red was right about Leonard when he and the other pigs stole the eggs from Bird Island and bombed Bird Village. One day later, Red and the other birds managed to go to Piggy Island, the pigs' home, and destroy Pig City and rescue the eggs, which only aggravated Leonard's hatred for the red bird. Despite this, the two were forced to cooperate to stop Zeta from conquering the earth.

King Pig
It is shown that Red hated King Pig Smooth Cheeks much more than he hated Leonard. While it is unknown how the two first met, perhaps the earliest incident involving both the monarch and the bird was when the former decided to steal the birds' eggs to eat them. Despite having been defeated countless times, King Pig has never given up, and this, as well as him surviving his encounters with the Angry Birds, has made him a constant threat to the eggs and a thorn to Red's side.

Prince Porky
Red is in neutral terms with Prince Porky. The two first met when King Pig sent Porky and Wizpig to steal the birds' eggs. While both were initially enemies, they had to team up after Wizpig betrayed the pigs and stole King Pig's crown and an egg. Later, at the Hog Head Mountain, Porky cooperated with the Red and his comrades to defeat Wizpig, who had just turned into Demonic Wizpig. Following that battle, Porky shared a time with the Angry Birds. The current state of Red's relationship with Porky remains unknown.
