Fluttershy's Mega Mewtwo · 5:33am Jan 29th, 2017
In the next chapter of Ponymon Girls 2, Fluttershy's Mewtwo will finally Mega Evolve, however, like Charizard, Mewtwo has two possible Mega Evolutions available to it, Mega Mewtwo X and Mega Mewtwo Y (although I beg to differ on the "Mega" concept for the second one because Mega Mewtwo Y is smaller and significantly lighter than Mewtwo is). Now this isn't a "you get to choose which one it'll get" post because before I started writing the story, I had already decided which one would be used. But you can still guess which one I'm going to use!
The Mega Mewtwos (X is on the left, Y is on the right)
y seems more like something flutters would have
