Some random guy offered a trade in ORAS, and gave me a Level 100 Shiny Haxorus. At first I thought, "this is obviously hacked..." But after looking through his default stats in Bulbapedia, I noticed that he only had ONE maxed out IV, which was Attack, at 432. (He was adamant) Nothing else is even close to maxed out. In fact, the rest of his stats are mediocre at best:
Exp. Points: 1,250,000
-Sp. Atk: 128
-Sp. Def: 170
What do you guys think? Is this thing hacked, or could I take it with me to competitive battles?
