Not necessarily. Individuals who have more extensive use and experience with their powers will usually be a step ahead of her.

That's not very different than what mystique does.

Mystique's mind also change with every transformation and her replication is as exact as could be.

Also unlike copycat, mystique can shape her body however she wants. If she wants claws, or a shark head, bat like wings, tendrils, a tail, she can as long as she imagines it.

I wouldnt say copycat is much better than mystique. Shes definitely not that powerful of a mutant

The only advantage copycat has is being able to mimic powers, but even that isnt super powerful. Shes not like Hope Summers level or Sync's level or even Rogues level

Yea even the superpowers the people have she can shapeshifters into people
