Zoey McMullen (character)

Zoey McMullen is the titular character of the Disney XD series of the same name. She is voiced by singer Selena Gomez, but occasionally she was voiced by Demi Lovato, as Gomez's stand in. To fans, she is branded as the "Disney Powerpuff Girl" due to her recycled design taken from the titular characters of The Powerpuff Girls.

Background
Zoey is a 6-year old heterochromic girl whose rather smart for her age as she is shown living in the animal-populated city of Theodore Street. She is sassy, friendly, optimistic, and selfless, but can get annoyed rather quickly.

She is hinted several times throughout the series to be Canadian, as evidenced by her love of pancakes topped with maple syrup and her rare catchphrase of "Eh", which she occasionally adds whenever she finishes speaking.
