fire blast
Beat Byron then get strength and then you can use it.
it is either overheat or blastburn
Any fire type pokemon, or a pokemon with a fire type move, I think poison too...
You cant. You will have to get fire red or leaf green if you want to trade kanto pokemon.
train all your Pokemon to level 70 and up or use hacks and get the 1 hit kill hack. Get every type of move (ground move, flying move, fire move, etc.) also get a bunch of hp potions, revives and status healers.
the most probable mistake is that you did not beat the gym.
You can find TM38 - fire blast at Lake Verity. You have to surf to the other end of the lake, and it is in the grass.
In Pokemon Pearl version, Rapidash is capable of learning various different moves. For example, it can learn the move fire blast.
If you are talking about Jasmine you just need a fighting type pokemon or a pokemon that knows a fighting type move. Or a fire pokemon or a pokemon that have fire type move is fine. And if you are talking about Sabrina she is a psychic type master so you will need a bug/ghost/dark type pokemon or a pokemon that have the move type.
Get a strong ground type (Torterra Garchomp*) or anything that has a ground type move
dig isn't a hm move on Pokemon pearl
Cut, Earthquake, Grass Knot and Razor Leaf. It beat my level 100 Infernape.
