Kinda funny how just like that, Mewtwo having a new form is nothing special now for the most part... And I noticed among the list of "Mega" Pokemon in the link posted, that MegaMiniMewtwo is the only one to not have a changed ability, while MegaBlaziken has Speed Boost, etc. So what, the awakened form just has Pressure like regular Mewtwo normally does? Lame sauce. Wasn't expecting it to have a different type or anything, but still.
I guess there's always that other new form that's said to resemble Mew more. Having two Mega forms while Blaziken, Lucario, etc. only have one would make Mewtwo stand out still at least.
