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 and had a crush on him later on.
Angie's only known Pokémon that she herself owns, she has it wherever she goes. During the Pokémon Summer Academy it became friends with Ash's Pikachu.
Angie received a Monferno during the Pokémon Summer Academy to train. It was her responsibility to train it for a battle later on in the day, but it had a bad attitude and wouldn't follow her orders. After Angie gained its respect, it fought for her against Ash's temporary Pokémon Raichu but ended the battle in a draw.
While taking care of a Lickitung for her parents, she accidentally allowed it to evolve into Lickilicky. Fearing her parents would be angry, she hid the Pokémon in its Poké Ball in a cave but it escaped and caused the people of the town to believe it was a monster. After finally gaining control over it, its Trainer came back for it, overjoyed, because his Lickitung had evolved.
