Xerneas, Yveltal and Zygarde are post game through a quest from Mable. I think thats it????

Answer 1

All three available legendaries are postgame exclusives.

Xerneas
L will tell you about Xerneas and Yveltal after you complete the story. Talk to Mable, and she will mention Alpha Pokemon in Wild Zones 3, 5, and 9. Defeating these will make Xerneas appear in Wild Zone 11.

Yveltal
After L informs you about Yveltal, talk to Vinnie to initiate battles against Rogue Mega Victreebel, Mega Hawlucha, and Mega Tyranitar. Defeating all of them will make Yveltal available to battle on the roof of Rouge Sector 2's Galerie de la Lune.

Zygarde
L will battle you after you catch Xerneas and Yveltal. Defeat him to make Zygarde appear; it can be caught after a battle.
