About Y/n: Y/n is a aura guardian from Alola, he travels to Kalos to learn more of mega evolution. He along with his shiny Latias and Latios will meet Ash at Professor Sycamore's lab. Y/n will have three Pokemon with him at the start, and their all shiny. Y/n himself doesn't know how it happened.

Y/n's Pokemon

1) Latias*/female (luxury ball)

2) Latios*/male(luxury ball)

Y/n and the shiny eon duo met when the latter two were hunted by Pokemon hunters, Y/n was near by and made some traps, the hunters were not to bright and was captured. Y/n then nursed the two back to health and they were  inseparable ever since. The duo also had their mega stones on them and F/n gave Y/n a Arceus ring keystone to help them mega evolve. 

3) Gyarados*/male(dive ball)

Y/n fished Gyarados up as he is, it took him awhile to get him to trust Y/n but now their bond is very strong. Gyarados has a habit of swathing anything that annoys him or his trainer, he found his  mega stone at a waterfall, he had to fight another Gyarados for it. 

If there any Pokemon you want in Y/n's team tell me in the comments, Y/n will have two people with him when his join's Ash, try to guess who they are.

Should Y/n catch the Kalos legends?

What trail type should be first? psychic, dragon or water?

Any legends outside of Kalos that you want me to catch, tell me how Y/n'll meet them.
