So, this is my first...OFFICIAL Mewtwo OC, and one that I've been growing very fond of! Her name is Diana, and her bio in the upper-right is paraphrased, but otherwise, further details about her are as follows:

Diana is a bioengineer who works primarily for the US government (hence the no mysterious formatting this time! :P). She works to ensure that the people of the world can live without fear of any illness, however her work and findings aren't always published, due to needing to be mass produced and the extreme costs some of her comes to. Nevertheless, she has won the Nobel Prize for finding the cure for cancer, despite it not being released to the general public. As a testament to her own work, she has modified her body to be naturally INvisible and rubbery as well. She's still biological in the fact that she still had organs and such, but she is hyper-elastic and completely unkillable by conventional weapons. It also means that she loves to be without any clothes the majority of the time...Five guesses as to why.

As a Pokemon, though, her psychic powers are a little above the natural strength of normal Mewtwo, however she primarily loves using her powers to stretch her body. She cannot naturally stretch like a muscle, so she's gotten good about using her powers to pull her body in all sorts of ways, even giving her the ability to contort her own shape if she so chooses. Nevertheless, she has even dabbled in the notion of being able to control a person's biology and molecular compounds with her mind, and has had success with it, though she's never published her findings on it.

Otherwise, I think that's about it on her bio! Anything else, you guys may find out in an RP!

UPDATE:
Forgot to mention, this was made by  livinlovindude which I must say, did a very good job of this! I like the invisibility appearance he did!
