Forget about the artificial/clay/magical duplicate stuff -- and stick to what worked for years. She was a regular human -- somehow ended up on Paradise Island -- and was embedded with Diana-level abilities -- either by scientific or supernatural means.

Eventually met up with the other 'sidekicks' and formed the Teen Titans.
