Bringing the Thunder
Wait, this is different from any information I've seen thus far. All information I find is that only when a ditto is the other parent that a hidden ability can't be passed on. I'll have to test this myself soon....
I VMd Serebii about it and he says this is the case, but I have never heard any requirement beyond needing a female with the ability. Nowhere have I seen anyone say that DW abilities can't be passed down via Ditto.
