Well, this was certainly another great chapter! It was really interesting learning more about Mewtwo specifically, as opposed to mostly the surroundings. I think you did an awesome job of characterizing by showing more than telling.
I think I noticed one mistake, though. The term "wetware-to-software" is written as "wetware-to-hardware" during the surgery. I'm not sure which one is correct, I guess it depends on whether Mewtwo sends commands to some kind of OS or whether she controls the components directly.
