See, I think you're missing the point of what I'm saying here, so let me simplify:
Plot involving newcomers being turned against each other = potentially AWESOME
Plot involving a pokemon (or several) reacting negatively to the flood of newcomers = potentially AWESOME
Mewtwo, specifically, doing the things you outlined for the reasons (or lack thereof) given = noooooooooooot something I can say I'm cool with at this point!
Your plot idea, in terms of characters turning against each other, can definitely 100% potentially work. Your idea of having a pokemon reacting to the newcomers can ALSO work. It's just combining the two in this particular way that it feels like you're stretching it. The reasons you're giving for Mewtwo being the "only option" makes it feel like you're just trying to shoehorn it into the role for sake of having a legendary pokemon, and you're totally ignoring the possibility of having another, separate plot to fit the bill of having a pokemon reacting.
I know I would be more than happy to help brainstorm and flesh out ideas for either or both plot options, and I think a lot of other people here would feel the same. But it's definitely concerning to me that you're basically thinking that this one idea is the only possible way for the plot to work, first of all because it doesn't feel like a plausible setup right now to me, and secondly because I can speak from literally years of RP experience that any major RP plot will not go according to plan. Ever. So if there's only one way it could possibly work, then it's going to be terribly hard to play out, since you'll NEED to be flexible to actually run an event like this. So there's a nickel's worth of free advice, there.
In any case, you asked for input, and that's what I have to say about it. I think both parts of the idea are sound- messing with people to having some good old PvP action, and having a powerful pokemon REACT to all the newcomers- but I don't think they work well combined as you have them, and I'm especially still very uneasy about Mewtwo's apparent role in proceedings, as it feels very out of character and inconsistent with game canon to me.
