Angie is a girl who lives in Sinnoh. She was first seen in the episode when Ash, Brock, and Dawn, attended a Week-Long Summer School program for Pokémon Trainers. She showed her confident side by testing Monferno (as a test of the Summer Academy), telling it to hit her with Ember and Mach Punch. While doing so, she dodged the practice attacks and taunted Monferno, sparking frustration. The result was that its power grew, and it beat her up to the point of bruises, which she didn't mind.
She served as the tomboyish rival/friend for Ash, even though she develops a friendship with him and had a crush on him later on.
