Diane

Diane originally was friends with Butler and hated the fact that he joined Team Magma. However, she hated the fact that he stole Jirachi even more, because he thought she wanted it. When the fake Groudon was rampaging, she was the first human after Team Rocket to get swallowed up. She was later released. She and Butler made a cameo during the ending-credits of Lucario and the Mystery of Mew.
