Well... in Y there are dragalge, noivern, garchomp, and flygon.
For stats:Dragalge :
Sp. Atk: 97
Sp. Def: 123
Overall, I would recommend noivern because it has a wide move pool and an amazing speed. The only problem is that you get noivern at the end of the game. But luckily you have a friend that can trade you one early in the game. Hope this helps!
