Pokémon Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! This rematch can be repeated once per day. After being defeated again, she once again tries to catch the player in a Poké Ball, but fails once again, and runs off once more, swearing to not give up on trying to get the player and Mewtwo for herself. Green can later be re-encountered in Cerulean City, where she will challenge the player to a rematch. After failing in doing so, she runs away, asking the player to consider her offer. She will then ask the player to become one of her Pokémon, along with Mewtwo, and throws several Poké Balls at them, attempting to catch them like a Pokémon. After being defeated, she will hand the player both of Mewtwo's Mega Stones: Mewtwonite X and Mewtwonite Y. Upon learning that the player managed to catch Mewtwo before her, she immediately challenges them to a battle. When first interacted with, she will toss a Poké Ball at the player, having mistaken them for a Pokémon. Green can then indeed be found inside Cerulean Cave, at the same spot where Mewtwo was earlier. After the player has caught Mewtwo in Cerulean Cave and exited the cave, Trace will appear again and mention how the girl looking for Mewtwo had entered the cave earlier. She is first mentioned by Trace after the player has become Champion as a girl looking to catch a powerful Pokémon spotted in Cerulean Cave.
