I did that thing where you went into a battle with your pokemon and someone ran and the video with my Umbreon on it was allowed on GTS it found the coding
It is 100% a hack then. The only Raikou that have the "Arrive from Hoenn" data are event Raikou's and said events all have the event name as the OT. Sorry man but your know my stance to hacks, still, at least you know.
I take that Milotic and I didn't really like the ev spread of them and I am going to make that eevee into a Defensive Leafeon oh and the Raikou arrived from hoenn aat lv.100
Yea I have an EV trained Milotic, need 100% sure on the EV's as it was a very long time ago but it's solid 335/115/276/249/292/189 Bold (Surf, Ice Beam, Rest Sleep Talk). I always use it in my mixed team and it always kicks ass.
BTW, I thought you were looking for Vaporeon, Leafeon, and Flareon?
