Does anyone know how to make a Pokemon forget a HM?

Move Deleter in Canalave City. His house is north of the Mart

You have to go to the move deleter in Canalave city.

You can't make a Pokemon forget a HM move. Sorry. Unless there is a code. I don't have an AR or GS so I wouldn't know about them. But I do know that once you teach a Pokemon an HM move, it can never forget it. ChEaTfReAk123

You must go and see the Move Deleter in the house just below the PokeCenter in Canalave, and ask him to delete the HM you want

In Canalave City from the Pokemon Center you go down, I think he's the house at the bottom.

Ok first go to canalave city and go inside the house above the poke mart then talk to the old dude and then you can delete the hm move

Go to Canalave City, and go to the first house south of the Pokemon Center. The Move Deleter should be in there. You should know the rest from there. Hope I helped.

Yes go or fly to Canavale City and the house right below the Pokemon Center has the Move Deleter who delete's ALL HM's & TM's.

go to a move deleter

In Canalave City, the third-highest house (from the bottom) has a move deleter. You can forget moves there.

To make a Pokemon forget a move go to calvane city and into the house below the pokemart and there you will meet the move deleter. For free he will delete any pokemons move .

Go to the move guy in canalave he is the "move forgetter"
