Jade's Three-Stage

Stage 1- Copy
Can copy powers that she sees. Cannot copy any powers that are personal, or powers that she doesn't have the physical capability to perform.

Stage 2- Parallel
Can imitate powers that should be physically impossible for her, and can copy some personal powers. Doesn't have to see the ability to copy it, powers she's seen before can be imitated.

Stage 3- Clone
Can copy powers that people haven't even developed yet, and can even imitate three-stage abilities.
