Zesty and Citrus (Pinky and the Brain):
Zesty is a child and has jet-black fur and red eyes. Despite her intimidating appearance, she is extremely bubbly, optimistic, and trusting, as well as a social butterfly. She talks with a slight Southern accent and has an older sister named Citrus. The two look a lot alike, except for Citrus has white paws, the tips of her ears are white, and she has a white patch of fur resembling an X on her stomach. Unlike her sister, Citrus is very distant, quiet, and bitter due to her being betrayed once. She won't trust anyone, sure that they will harm her or her sister, the only one who can make her smile.
Zesty and Citrus have a younger brother named Basil, who they are searching for. Basil has a very distinctive white stripe down his back, and he has one blue eye and one light green. Along the way, Zesty and Citrus encounter Pinky and the Brain on their nightly quest for world domination, and they agree to help each other.
