Selfdestruct at 38

Ferrothorn:
Power Whip at 40 (no surprise here)
Iron Head at 46
Payback at 53
Flash Cannon at 61

 

[El_Sargento]

Apparently, Ferrothorn Hidden Ability is Anticipate.
Discovered in a Inverse Battle in that house within Route 18.

 

[leingodf8]

Can relearn Rock Climb (level 1 i assume)

 

[Blitz]

Since it's not mentioned here, Selfdestruct has been renamed to Self-Destruct (and it does get it at level 38).

[VioletPumpkin]

Ferroseed supposedly gets Acid Spray and Rock Climb as egg moves now, which someone should confirm. While Ferrothorn already learned Rock Climb, Ferroseed could not.

 

[VioletPumpkin]

Confirming both of the above moves. Acid Spray from Trubbish, Rock Climb from Ferrothorn.

Proof
