    This is good for mewtwo, giving younger viewers a taste of red and blue but with a twist

  • #2 ratrace2thegame

    I know that some pokemon spriters have been respriting Mewtwo like this I hope their happy to see this. But I cant believe that I have to get attached to another mega mewtwo form.

  • #3 jake20092

    This is amazing. I might get Pokémon X instead of Y just because of this form.

  • #4 Nightblade370

    This form is just too cool. I was a little disappointed that Mewtwo lost its edge with its Y form and I wished there was a better design for it, but this wins it for me. Pokemon X, here I come.

    And luckily i preordered X instead of Y... =u=
    That form looks a whole lot cooler c:

  • #6 I_Like_Milk

    I'm so glad I pre-ordered X. Everything I love is in X. I love Clauncher, I love Swirlix, and now I get an epic ninja alien that should consider being in Starfleet. Live long and prosper.

    now i'm begging my mom to pre-order pokemon x.

    No offense but why Darkrai? It may look awesome but probably won't be that awesome in battle... A Mega Thunderus would be OP
