A year ago I got a Dragonite in Wonder Trade. Here is the info:
Max IVs lvl 100 HA Adamant (Knows all Physical moves) OT: DANIEL (All caps) ID: 273000 Where: Faraway Place (XY) Fly (I taught it that) Dragon Claw Waterfall (I taught it that) Iron Head HP: 323 Attack: 403 Sp. Atk: 213 Sp. Def: 236 Spd: 259
This Dragonite doesn't seem to be hacked. The stats are easily reached, as long as it has max attack, 4 EV's SpA, and 252 EV's in Speed. If you could provide the stats in Defense, it would be easier. And you can get a Dragonite in X+Y
