Chicken Little was originally written as a female character and was going to be voiced by Holly Hunter, though plans shifted when executives asked for more of a father-son dynamic in the film.
He is smart indeed. But Chicken Little worries about everything sometimes and try to get a lot of attention to everybody to prove that the sky is falling. Chicken Little is kind and supportive to the people he cares about.
Chicken Little has white feathers and a red rooster comb. He wears a green and white striped T-shirt, green glasses, and brown shorts.
After Chicken Little sees a hexagon-shaped object with an image of the sky fall from the sky, he believes that the sky itself is falling, and tries to warn the town, but in doing so, he throws the town into a panic that causes him to be accused of being insane. One year later, Buck then explains to him about the public getting more attention from Little as his father drops him off to school.
Unable to catch the bus, Chicken Little starts to get late for school as he uses a bottle of orange soda to get inside the school where he hides in one of the lockers to avoid getting caught by the other citizens. During Mr. Woolensworth's class, Goosey Loosey points out that he did not show up on time as he is marked "tardy" for a class as Woolensworth asks his class to translate each page into mutton by bleating like a sheep.
A misfit ever since and the target of bullies, Chicken Little and his small circle of friends have since been trying to figure a way for him to change his image; for example during a game of dodgeball, Chicken Little's classmate Abby Mallard encourages him to make closure with his father in which she explains to him to stop causing the same problem as he did to the town from last year. Later, he ends up getting bullied by Foxy Loxy and Goosey Loosey, launching him on a window dropping down to pull a lever triggering the fire alarm, shocking the coach. Later, Little is sent to Principal Fetchit's office where he talks to his father about the inappropriate things he did at school. After a talk with the principal, Buck explains to his son not to talk about the inappropriate things he did at school earlier. Later that night, Chicken Little explains to his father that he wants to be in the baseball team, but his father tells him to choose another activity such as chess. When Chicken Little and his father return home, Little sits on the rooftop where he looks at the sky where he wishes for his dream to come true.
The next day, Chicken Little sees an opportunity and tries signing up for the school baseball team, as his father did years ago, but he ends up training in order to be in a better player where Foxy Loxy constantly keeps winning many games. Later after Little trains hard, Chicken Little goes to the field to win the game, despite a puma being worried that he might lose the game again just like what Foxy did to him albeit almost getting three strikes during his game. Little ends up hitting the ball as the commentator, the crowd, his father Buck, and even Turkey Lurkey, tell him to run. Almost losing the game, the umpire explains to the crowd and announcer that he is still safe in which Chicken Little eventually ends up winning the game, beating Foxy. After winning, Chicken Little is satisfied with his victory at home as he talks to his father about his victory, making him popular again. Later that night, Little ends up getting hit by a hexagonal object where he discovers a large glow in the sky, where he grabs the hexagonal object as he decides to call his best friend Abby Mallard to warn her about the hexagonal object.
Little then explains to Abby, Runt, and Fish about the object falling from the sky. When Fish Out of Water interacts with the object, Little, Abby, and Runt leave the house where they see the green glow in the sky because of Fish interacting with the object in which the all of Oakey Oaks starts to tremble when a lot of galactic activity and hexagonal objects start to unravel things where aliens patrol Oakey Oaks where they plan to rescue Fish from the aliens in the UFO. Upon rescuing him, Little, Abby, Runt, and Fish are worried about the aliens preparing to take over Earth where they plan to escape the UFO where they plan to ask Little's father Buck Cluck. Later when two aliens try to close the hatch, they are unable to due to Chicken Little holding the button.
Eventually, Little, Abby, Runt, and Fish manage to escape albeit with the aliens attacking them. While hiding in a cornfield, Abby tells Chicken Little, Ruby, and Fish to go to the school bell at Oakey Oaks Middle School to warn all the citizens of Oakey Oaks about the alien invasion. Little then tells Abby, Runt, and Fish that he needs a bottle of soda to reach the school bell (just like what Little did to get to school when he is getting late). Reaching the bell, Little remembers trying to warn the town about the sky falling from the sky and the people accusing him of being insane, so he warns the citizens of Oakey Oaks again of the falling sky where the UFO constantly disappears when Little points out to the citizens about his experience where a big panic happens in Chicken Little's neighborhood as he tries to figure out the truth behind the falling piece. The citizens then believe that Little is making up the story, but Little explains to them about the truth in which the citizens do not see the aliens and the UFO.
The next day, Little feels sad that he is too worried to talk to his father about the falling sky last night, but eventually discovers a small alien named Kirby whom the aliens are planning to rescue last night. Later when dozens of UFOs invade Oakey Oaks as the aliens are planning to attack, Little's experience finally becomes true as the aliens send ground troops to protect Kirby from the citizens of Oakey Oaks. When Little goes after Kirby, he and Kirby end up in the movie theater where he explains to Buck and Abby about the truth he discovered. Chicken Little explains to Buck and Abby to return the alien Kirby back to his parents in order to stop the invasion.
Later after leaving the movie theater, Little explains to his father to take Kirby to the alien so that Kirby could return home. When the alien looks at Buck holding Kirby (thinking Little's father is attacking him), the alien plans to abduct him as he and Little hide to avoid getting caught as Little plans to bring Kirby back to his parents. Chicken Little and his father plan to go to the UFO where Kirby's parents would be at, albeit with the alien ground troops attacking with the help of Runt, Abby, and Fish to help Kirby reunite with his parents. Little eventually reaches to the top of the school where he tells the aliens that he is ready to bring Kirby to them to stop the attack. Later, Chicken Little and his father get abducted in the UFO where Kirby's father accuses the two of taking his son. Eventually, Kirby's father prepares to take out the two as his wife explains to him that Kirby is telling the truth as his wife tells him to put away the weapons as well as putting Chicken Little and his father down as a misunderstanding. The aliens then bring Chicken Little and his father back to Oakey Oaks as the aliens leave Oakey Oaks to get back to outer space.
After the aliens leave, Chicken Little and his father, along with the citizens of Oakey Oaks watch a movie about him where they watch a movie starring a future version of himself in they all like the movie about him.
Later during the credits, Chicken Little and the citizens of Oakey Oaks sing "Don't Go Breaking My Heart" where Little and his father dance along together.
Chicken Little is a Summon that appears in Kingdom Hearts II. He is obtained by talking to Merlin after visiting the Land of Dragons and Beast's Castle (or Olympus Coliseum if Sora skipped either of the aforementioned worlds). To summon him, Sora uses the Baseball Charm he receives from Merlin.
When Sora, Donald, and Goofy return to Hollow Bastion they reunite with old friends and Sora's magic instructor Merlin who re-teaches Sora some magic attacks, he then gives Sora a special baseball charm to help him along his journey. The charm summons Chicken Little who teams up with Sora and throws baseballs at enemies to stun them. Chicken Little also has a limit called FPS (First Person Shooter) Mode, which allows Sora to shoot firecrackers or baseballs at enemies through a scope in a first person shooter style.
