Peter's ability was the power to copy other people's powers. In the beginning he had to be near them which is why it was considered empathic by most. By the end of the show he didn't have to be near them. I always heard his power called "copying". It's also why I won't allow it. It gives the person too many advantages.

Phoebe from Charmed is the perfect empath example.
