This isn't exactly a new shiny per se, as I've had him for a while, but I'd thought I'd share this monstrosity with you all.

Yes, that is my shiny Zelrom's wing in the background. Or in the foreground, I suppose. Anyway yeah shiny Mega Rayquaza. Literally the most overpowered thing I have ever seen. Apparently it's only on par with Mega Mewtwo X and Y for both base attack and special attack respectively, but geez... Mine has 452 Attack in this form even without a beneficial nature or good IVs. It is fully EV trained though so I suppose that helps.
Soooo feel to correct me if I am wrong here. But Rayquaza can't be shiny in ORAS and only the Rayquaza from ORAS Sky Pillar can learn Dragons Ascent which allows it to go mega right? So how do you have a shiny Mega Razyquaza?
As for my Raikou hunt I am at 650ish SRs for him right now. Been slowly hunting with my bust work schedule xD
