Abby is a character appearing in Pokémon: Advanced Challenge.
Abby is a former Pokémon Coordinator that won the Grand Festival on her first and only year with the help of her Skitty, Johnny. Later on, she met Dr. Moss, who treated Johnny following a Flygon attack. Abby was inspired to become as great a doctor as he was, and was one day awarded a Moon Stone by him for her breakthroughs in Pokémon message therapy, evolving Johnny into a Delcatty. In the present she meets Ash Ketchum and friends, treating May's Skitty after breathing in smoke from Ash's Torkoal and teaching it Blizzard.
