I don't know if it's been mentioned yet, but Greninja seems to learn Spikes by level up, sometime before evolution. The move showed up at the relearner's place, but it wasn't grouped with all of the other moves Greninja learns at level 1 -- which included Night Slash, by the way. I have no pictures to use as proof, but it shouldn't be too hard to confirm.
My Greninja just tried to learn Haze at level 56, and was not compatible with the Swords Dance TM.
Aerodactyl learns Iron Head at level 1 now.
