Since Heroes canon hasn't seen fit to make it 100% clear if Peter's powers are mutation, inherent, and/or some form of other:
Peter can copy the power of any power-inclined person he happens to be near. Touching them helps with the pickup but it is not required.
As far as canon's shown it looks like the power's strongest when he's right next to the person and that it gradually fades over time rather than disappearing entirely once there's distance (e.g. when he drew prophetic stick figures long after he'd been with Isaac).
For FH purposes I've been extrapolating that he can't repete gods, angels/devils, or things that are a matter of species (e.g. he couldn't gameface if he was next to a vamp).
