Pinkie Pie

Pinkie Pie is a female Earth pony from the MLP:FiM series. Her MLP:FiM counterpart differs from her Goldieverse version in several aspects, but both versions still retain the same general characteristics.

Depiction in MLP:FiM
Pinkie in MLP:FiM is shown to be hyper, excitable, and outgoing. She loves parties and is very cartoonish. Shown to have an insecure side when feeling as if her friends don't like her.

Depiction in the Goldieverse
Pinkie Pie in the Goldieverse is shown to be a little more "detached" from her pony friends, even though they are still very close. Her friends don't seem to mind this. Pinkie is a member of Princess Goldie's "Dark Side", along with Sunset Shimmer, Discord, and a variety of other villains. She is also Goldie's apprentice. It is undefined what this means, but she has shown that she is able to do magic far greater than that of a normal earth pony. Although, this could just be Pinkie Pie.
