Gayquaza

Is there any Pokemon stronger than Rayquaza?

And I’m not talking about base form Rayquaza. I’m talking about fully transformed Mega Rayquaza with maximum IVs and Dragon Ascent and with Dragon-Dancing techniques, V-Create, a perfect EV spread and control of the weather and his signature Delta Stream and flying-type STAB, with AZ's Infinity Energy and all keystones of the Draconids implanted in him so he has a mega form and can hold items at the same time.
