You can't use something that you do not have.
Get one of your Pokemon to use HM Cut on it.
You can only use the HM dig in a cave, but it takes you to where you came in!
Yes you can. All HM items can be utilized numerous times.
Yes for HM Waterfall, Goldeen and Seaking can learn waterfall without using the HM by leveling up.
trade in a Pokemon that has it, but it wont be able to use it outside of battke
to get the hm dive use waterfall on the one leading to the Pokemon league and then go in the poke center and talk to the girl behind the till
In Pokémon FireRed, for defeating Brock, his Badge will allow you the use of the Flash HM, Misty's Badge will allow you to use the Cut HM, Lt. Surge's Badge will allow you the use of the Fly HM, Erika's Badge will allow you the use of the Strength HM and Koga's Badge will allow you the use of the Surf HM.
You use HM's just like you would with TM's, you click A on it and select use, then you select a pokemon who you wish it to learn the HM, then once it learns it you will be able to use that move outside of battle and inside of battle. TM's are one use only and should be used with caution. HM's have an infinite amount of uses, but cannot easily be forgotten, as they can only be forgotten by the Move Deleter
There are, specifically only hm in one km....since you asked: there are exactly 10 hm in one km so, there are 0,1 km in 1 hm
The first HM that you are able to use outside of battle is the Cut HM. You get it from talking to the captain in the S.S. Anne.
you go through Mt. Cornett with strength and rock smash and surf
No Pokemon learns cut on there own so you need to use the HM to teach the move.
