Where can I get a Weak Armor Omanyte in Pokemon X/Y?

Question

I have crappy Friend Safaris so I'm crossing my fingers.

Answer 1

Unfortunately, it is only available through Poketransfer.

Omanyte's Hidden Ability is Weak Armor, and since the only way to get Omanyte is through fossil reviving, it is impossible. Therefore, you can only get it through transfer. Sorry. :(

Hope I helped. :)
