A CRAU from a 6-year-old Pokemon-based game would be fine! Please list her powers out on the app and we will let you know any limits we might have to place. All powers will be nerfed upon arrival, and can be regained through bonus activity instead of canon abilities. For non-human characters, it's the player's choice whether they want to retain the appearance from the start, or have the character be humanized and regain other traits through bonus activity.

If you need any more clarification, please let us know!
