I posted this in another thread, but from what another anon said, Mewtwo Y's maximum possible Special Attack it can get is 570 normally, and 2280 with 4x boostan. I'll assume for the sake of sanity until we get stats on Mewtwo X that it's the same here.
I decided to figure out the damage this thing can do to a pokemon that's 4x weak to it, say Toxicroak that's set to maximum defense stat for it. With that said, this is about what I got for math-wise:
0.84 (lvl 100 Mewtwo) * (570/251) * 100 + 2 = 192
0.84 * (2280/251) * 100 + 2 = 765
Then, we use the modifier to get total damage for a normal max defense Toxicroak:
192 * 6 = 1152
765 * 6 = 4596
And since a crit means * 2, that means for your grand total.....
A psystrike with Mega Mewtwo Y maxed out on Special Attack will do about 1152 damage, 2304 damage if it crits normally, and will do 4596 damage, 9192 damage if crits for maximum possible damage.
Either way, one psystrike, and this thing is killing a LOT of thing in one hit if not ready for it. Trust me, I've done the math, and unless it's a dark type, this thing is a god damn BEAST.
