Fennekin first appeared in XY003 as one of the three starter Pokémon new Pokémon Trainers could choose from Professor Sycamore. In XY004, Serena chose Fennekin as her starter Pokémon. Later in the same episode, Fennekin chased a wild Vespiquen that was about to attack Serena away with Ember, demonstrating courage and care for its trainer.
In XY005 Fennekin woke up with Serena at a Pokémon Center and enjoyed a large breakfast with her. Fennekin mimiced Serena's actions during their breakfast by stretching as the same time she did. Later in the same episode, it was introduced to Ash, Clemont, and Bonnie and greeted them happily.
