Personality
Pinkie Pie is an outgoing, optimistic, cheerful, energetic, happy and hyperactive pony who loves sweets and often speaks and acts in non sequiturs. Loving to make ponies laugh and put a smile on their faces. She has a fondness of parties and a tendency to throw them on a whim. Pinkie Pie plays many instruments and frequently breaks out into song. She also tends to hop rather than walk, usually accompanied by a springing noise. She is often not taken seriously even by her closest friends. She is almost always excited, and manages to keep her excitement after winning thirty-five consecutive games of tic-tac-toe against Rarity while they wait for Fluttershy to catch up.

Pinkie Pie teaches the other ponies to laugh at their fears and helps Twilight Sparkle accept things even if she doesn't understand them. She plays a series of pranks on the residents of Ponyville with Rainbow Dash, saying that she loves to have fun. She is very conscientious about this, though: when she pranks someone it's in such a way that no harm is done and the victim gets a laugh from it too. As an example, she once painted all of the apples on Applejack's trees. Applejack was originally furious until she found that the paint was water-soluble. She'll never prank someone if she knows it might hurt them, such as Fluttershy, because of her extreme sensitivity.

Keyblade
Pinkie pie gained the ability to wield the Keyblade when her and her friends wished they could help Sora, Donald, and Goofy fight the Heartless to protect there home.

Partying
Pinkie Pie is first introduced as a talented party-thrower. She runs off to plan a party for Twilight Sparkle immediately after seeing her for the first time; Her first party ever was thrown for her family, which is how she got her cutie mark according to her own telling. She throws Gilda a welcome party and Gummy a birthday party.

Singing, dancing, playing music
Pinkie frequently sings songs of her own writing, but the other ponies' reactions are not always favorable. Her friends react skeptically when she begins singing for the first time, and her audience reacts very negatively to her song-and-dance routine. Similarly, Twilight Sparkle is not impressed with Pinkie's little ditty, and the ponies attending the Grand Galloping Gala don't take to her song at all.

Baking
Pinkie Pie works at Sugarcube Corner, a confectionery in Ponyville.

Pinkie also creates other edible treats and the like.

Ice-skating
Pinkie Pie is an exceptional ice skater, stating that she's been skating since she was "an itty-bitty liddle-widdle twinkie-Pinkie".

Pursuit
Pinkie Pie is very apt at appearing right next to her target. Pinkie can evenly match Rainbow Dash's flying speed, where she pursues the Pegasus and appears right next to her at her destination, sometimes being present even before Rainbow Dash reaches the destination.

Pinkie Sense
Pinkie Pie has a strange ability to predict the future through various twitches and involuntary motions made by her body. Applejack explains that the ponies in Ponyville pay heed to Pinkie Pie's "Pinkie Sense", even going so far as to catalog them, especially given that her twitches may just as easily end up affecting them. The ability goes largely unquestioned by Pinkie Pie and the others. This annoys Twilight Sparkle to no end, and she insists on finding an explanation for this ability. First she hooks her up to some sort of measuring apparatus that produces no results, then she follows her and makes notes of her various twitches and the ensuing events.

Memory
Pinkie is shown to have an Eidetic memory. It is stated that Pinkie Pie has a very strong memory, enough to "remember everything about everypony in Ponyville."

However, it was hinted at before that Pinkie Pie was able to remember every single citizen in Ponyville.
