Could I have a list of Hidden Abilities that are available as of gen VI?

Question

Not only am I asking for Hidden Abilities of Pokemon from Friend Safari, but also Pokemon with Hidden Abilities that can be transferred from B/W/B2/W2 that are from Hidden Grottos and special events such as the Musharna that appears every Friday, the Braviary/Vullaby that appears on the Route near Desert Resort in B2/W2, etc.

Answer 1

Here is a list, you have everything your asking for. The one from bw/bw2 are at the bottom of the list.
