Sally (US)

Sally is an OC created by Fanfictiondreamer; she was a Dalmatian character that was from the Road Rovers, but she was based on a birthday gift she received from her grandfather. The washable 101 Dalmatian doll was a memo of sorts, as a way to still remember him. She debuted in the prequel to The Ultimate Story, the Lisa Simpson Chronicles. She's actually Lisa Simpson's and Maggie Simpson's own dog they retrieved from the Road Rovers, before they actually met The Powerpuff Girls. She goes on all sorts of adventures with them, even when they went to Mobius and received their magical powers from Taj. Since then, she functions as a telepath much like her Simpson owners.

In the first Ultimate Story, Sally stays behind to monitor Earth as Lisa and her team find the owner of the mysterious backpack Ly described, who later turned out to be Misty. Lisa doesn't see Sally for over a year, as she trains Misty for her fairy training in Corneria. She sees Sally again as the dog senses immense evil over the world causing her and Lisa to get sick. The latter was able to reverse it all as she cleansed the planet with her overdeveloping fairy powers. Them, she returns to Corneria and resumes her tutoring with Misty.

In the Journey through Kanto, Sally helps the team indirectly as she guides Lisa and Ash sensing out Darkness. Last time she became intrigued by Team Rocket and the Light energy from their benevolent clones, as well as tracing locations for the mysterious 10 Pokémon Stones.

She's been seen very scarcely after that. But she still stays loyal with Lisa and Maggie.
