This Gogoat is a Grass-type Pokémon owned by Alexa.
When Alexa managed to find Helioptile (who, due to its docile nature, was startled and attacked Ash and Pikachu), Gogoat came to Alexa. Alexa introduced herself, as well as her Pokémon, to the heroes, claiming she was from Kalos. Alexa explained she was a journalist and went through her bag to find a magazine, but Gogoat reminded her it was in the other one. Later on, Gogoat also reminded Alexa her recharger for the camera was also in the other bag, since she was forgetful. Seeing her camera was empty, Alexa split with the group for a while, since she needed to make a video for her article.
