Shapeshifting

Summary

Capabilities
Just as said above one more, Shapeshiftng allows the user to reshape and transform themselves on a genetic level to in order to impersonate someone or something, like another human being or an alien or even an animal/machine and so on.

By doing this, and depending on what form they take, one can enhance their abilities based on the particular form they've chosen weather its through becoming a type of animal, a machine, or just whatever form will allow them to boost their stats altogether.
