This has been asked before here, but the info is outdated with the release of X and Y, so it'd be nice to know the list of Gen VI signature moves.
If I had to name them they would be:
Chesnaught - Spiky Shield (Protect with a bonus)
Delphox - Mystic Fire
Greninja - Water Shuriken and Mat Block
Pancham/Pangoro - Parting Shot
Inkay/Malamar - Topsy-Turvy
Hawlucha - Flying Press (A flying/fighting type move)
Klefki - Crafty Shield
Xerneas - Geomancy
Yveltal - Oblivion Wing
Zygarde - Land's Wrath
And I'm thinking Aegislash with King's Shield also counts though not sure if it can be breed.
