Meowzie is a female Meowth.
Meowth met Meowzie in Holywood and fell in love with her. He attempted to gain trust from her, but she refused, as she wanted someone rich and more human. Meowth was pounded by her owner, but Meowth got an idea how to impress her. Meowth learned how to walk and talk like a human. However, he was turned down as he was not rich, so he joined Team Rocket to become wealthy.
After Meowth talked with his former gang, he saw Meowzie, who told him that her owner abandoned her, as she couldn't afford more money to keep Meowzie. When Meowth defeated Persian (his old gang's leader), Meowzie took care of Persian, as Persian offered her help when nobody other did. Meowth was heartbroken and left them.
Although never physically appearing in any other episodes, she appears in several fantasies of Meowth's.
None of Meowzie's moves are known.
