Based on a new scan this features Gogoat and a character named Pansy. Since the image isn't clear, i am not sure but it seems that a Helioptile is also there.
"Alexa is a Pokémon journalist who would travel with Ash and friends until they get back to Kanto. She also brings with her Helioptile, Gogoat, and Noivern."
