Do I keep it? I got it off the GTS after trying to get rid of my own Naughty natured Manaphy. After raising this one to lvl 18 in the daycare, I used MetalKid's IV calculator. All 27-31 IVs, and with levelling up they should be perfect. So should I use it regardless of the lousy nature? I'm not that bothered that it was probably (99.999%) hacked.
