Stephanie Mitchell is the co-leader of the Invasive Mew Mews, along with her best friend, Tiffany Bell. She is one of the primany antagonists and is the first Invasive Mew to be introduced along with Tiffany. She was willingly injected with the DNA of the Common Myna because she was bullied and wanted to be able to defend herself, and the prospect of super powers was too good to pass up. However, the DNA she was injected with was corrupted because it was from an invasive species, and she, like the rest of the Invasive Mews, was overpowered by the instincts.
- Stephanie has an odd attraction to shiny things, much like a bird. She collects them and displays them about her living quarters.
- She likes to do Tiffany's hair, like social preening seen in many bird species.
