Encounter 1: Cerulean Cave

Location: Cerulean Cave

After defeating the Elite Four, you will get informed by your Rival of a mysterious Pokémon in Cerulean Cave. When you go there, he will mention about both him and a girl wanting to go find Mewtwo. Capture Mewtwo and your rival will tell you that the girl is still inside the cave. Go all the way back to where Mewtwo was and you'll find Green. When you speak to her, she'll throw a Poké Ball at you thinking that you're a Pokémon as it's dark. She'll soon apologise and then will challenge you to a battle after seeing you had obtained Mewtwo. She uses Mega Blastoise.
