Abigail is a character of the day who appeared in Cooking Up a Sweet Story. She runs a Sinnoh bakery café alongside her niece Theresa. Abigail is also a bake-off champion.

Her Pikachu, nicknamed Sugar, ran away to try to find a way to toast some Aspear Berries for an upcoming bake-off competition. Determined to assist Abigail, Theresa found Ash's Pikachu for a substitute for Sugar. The ploy worked for a while, with Abigail using Pikachu to forrage for Berries. Abigail and Pikachu later challenged Ash to a battle. Just before Aipom was about to hurt Pikachu for the first time, she threw in the towel and quit.

Finally, as Ash was about to reveal the truth, Abigail revealed that she already knew that Ash's Pikachu wasn't her Sugar. Soon after, Team Rocket came and kidnapped Pikachu. Abigail inspired everyone to chase after Team Rocket's latest mecha. Sugar came back as a Raichu and rescued Pikachu. In the end, Sugar helped Abigail make an amazing cake, using its powerful Thunderbolt and Focus Punch.
