OK sorry for double posting but I am starting to "study" the base status of this Aevium versions and I'm doing that by leveling them without any EV trained and with neutral Nature, so far these are my findings:
A-Misdreavus: Her Sp.Def and Atk were swapped so now it's 60 HP, 85 Atk, 60 Def, 85 S.Atk, 60 S.Def and 85 Speed
A-Litwick: No changes
A-Paras: No changes
A-Feebas: No changes
A-Lapras: No changes
Will check later when I get the time the A-Mareep and A-Munna
