O Mega Rayquaza (não é Primal, coisa "a ser explicada na história) foi hoje revelado e este tem a habilidade Delta Stream que não permite mudanças de clima mas também protege os Pokémons do tipo Flying das suas fraquezas ao receber apenas danos normais de ataques Rock, Ice e Electric.

Brimming with the overwhelming power granted by the energy of nature, this transformation was named by later people "Primal Reversion." And the people called their tormentors Primal Groudon and Primal Kyogre.

The people, unable to endure any more, cried out to their mighty savior Rayquaza before a great stone that shone with rainbow brilliance. And a change came upon Rayquaza, weaving in the sky above Primal Groudon and Primal Kyogre. Suffused in brilliant light, its body began to transform visibly. And then...
