Assunta is a minor character who showed up in the Indigo Plateau Conference episode "Friends to the End." She's best known for her first-round match against Ritchie, which came down to a one-on-one showdown between her Ivysaur and his Pikachu, Sparky. Assunta pulled off the win, catching Ash and the others off guard and earning her spot in the semifinals.
What happened to her after that remains unclear, though there's a silhouette near the end of the episode that looks a lot like her—suggesting she might've made it all the way to the finals before losing out.
