To delete HM moves go to the move deleter in canalave city,
This was my first answer on wikianswers- !!
The only way to delete HM's is to have the Move Deleter in Canalave City do it for you.
To delete an HM move, you must go to the move deleter in Fushia city. He can delete any move you want to... even a HM move! but don't forget that after that HM is deleted that Pokemon only has 3 moves left so teach it another move!
yes
It's impossible to deleat a HM.
go to the move deleter to delete moves such as HM
Go to blackthorn city and find the move deleter's house he will delete anyone of your pokemon's moves including HM's.
Go to Lillycove City and in that town there is a move deleter who will delete any move (Including HM's) for free.
If you mean delete a HM move that has already been learned, you can go to the Move Deleter's house which (I think) you can find in Lilycove City. But if you meant delete the whole HM item, it cannot be done because it is an important item.
If by delete a HM you mean get rid of said HM you can't. Otherwise if you want to get rid of an HM move a Pokemon has learned, go to the Move Deleter in Lilycove City. His house is to the left of the Lilycove Department Store.
you cant our you will have to a cheat
You can delete HM Moves via the Move Deleter, who is located in Canalave City.
after you get more than for moves by the pokemon's level or using a hm or tm you can select one to delete. if it is an HM, then you need to go to canvalae city and go into this house with a old man in it he will ask you if u want to delete a move
