talk with steven
in the MOSSDEEP
Steven will give it to you
go to mossdeep city. Go to the house behind the house that's to the left of the Pokemon center. this is steven's house. talk to him, and he will give you HM Dive.
it isn't in Pokemon platinum its in ruby and Sapphire
You cannot get HM Dive in Pokémon LeafGreen.Since Dive is not an HM in leafgreen the only way to get one of your Pokemon to learn Dive is to trade it to ruby, sapphire or emerald then teach it Dive using the HM then trade it back to leafgreen.
there's no hm dive in firered.so that means you can't find it.but you can find it in Pokemon ruby,sapphire,emerald and more.
After beating tate and liza head to steven's house in mossdeep city he will give you the HM Dive.
There is no HM called dive in Pokemon Diamond you fat oaf.
You can't unless you trade a Pokemon from Pokemon Ruby, Sapphire or Emerald and get a Pokemon that knows Dive. The HM Dive is not necessary in Pokemon Firered and is thus not avaliable. However, a Pokemon that knows Dive can be traded from Pokemon Sapphire, Ruby or Emerald version to Firered.can notI can't remember much, but I think you have to get it from Wallace or Juan.
Dive is not an HM in leafgreen however some Pokemon can learn it on there own, if you want to have a Pokemon with dive have the Pokemon that you want learn dive in ruby or sapphire or emerald then have them trade you it and now you can use dive but not outside of battle because its not an HM.
