Chicken Little was originally written as a female character, to have been voiced by Holly Hunter, though plans shifted when executives asked for more of a father-son dynamic in the film.
After 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. This causes him to be accused of being insane by everyone, including his own father Buck, and Little is shocked that own father will not believe him.
This supposedly incident that Little caused has become so popular that the movie directors are advertising a movie called "The Crazy Chicken" which will be about Little's havoc he caused. Buck wonders if everyone will ever forget his mistake. Chicken wants to show everyone he is not crazy.
An outcast however ever since and the target of bullies, Little and his small circle of friends have since been trying to figure a way for him to change his image. Little sees an opportunity and tries signing up for the school baseball team, like his father was years ago.
Little ends up winning the game and is seen as popular again, but another incident with a hexagonal object and other signs of alien activity begins to unravel things.

Kingdom Hearts II
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 Little who teams up with Sora and throws baseballs at enemies to stun them. 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.
