I'd still trade but I need to figure out cloning first I'm still having some issues.
One way of checking hacks is location, check if the Pokemon can actually be caught at the location it says it was. You could also put the stats into metal kid's IV Calculator (google ) If it says they're impossible then it's hacked.
EDIT: Latios IVs: Latios - #381 (Calm) : 12 - 13 / 28 - 29 / 26 - 27 / Impossible / 28 - 30 / 30 - 31
Not sure if the SpA IV is because of Soul Dew or if it's a hack :/
