Lisa Fox is one of Emily Elephant's friends. She befriended Peppa in the episode Fantastic Lisa Fox, but hung out with Brianna Bear and Emily Elephant again in later episodes. She has a cat that hates spreadable ham even more than Brianna Bear's dog does. She doesn't dislike Peppa as much as Emily and Brianna do. She was the first character and the only fanon character to have freckles.

Lisa is the sister of Freddy Fox. She often says "I agree" and Brianna Bear says "Even more" afterwards on each episode. She has a green and purple dress. Like Rebecca Rabbit in Poppies and Puddles her dress's color does not change but it is now more muted. She has a green hat with a purple bow at the front that is only seen in Poppies and Puddles.
