So, I think in essence there isn't much difference between a copycat and Peter, right? Both acquire abilities without conscious efforts.

Except perhaps a copycat needs to stay alive in order to mimic... Oh, I'm not sure about that, does she really need to maintain a breathing status while copying new ability? The extend of her potentials is not fully disclosed yet; can she learn indestructabiliy and applies the very convenient skill in the future...errr...death occasion?

I'm glad the super-size copycat Peter is back in action.
