Ace "Chicken Little" Cluck

Ace "Chicken Little" Cluck is the titular protagonist of the 2005 Disney animated film of the same name.

Development
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.

Personality
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.

Physical appearance
Chicken Little has white feathers and a red rooster comb. He wears a green and white striped T-shirt, green glasses, and brown shorts.

Chicken Little
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. An 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, Chicken Little's best friend Abby Mallard encourages him to make closure with his dad. Chicken Little sees an opportunity and tries signing up for the school baseball team, like his father was years ago. Chicken 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. A lot happens in Chicken Little's small neighborhood as he tries to figure out the truth behind the falling piece.

Kingdom Hearts II
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.

Disney Parks
Chicken Little and Abby used to have appeared as figures in Disney Parks. Afterwards, Chicken Little has not been seen in the US parks for a few years, except for special events such as the Easter parade. Anyone's best bet to meet him is at Disneyland Paris; however, even there he is a rare character.
