To beat fire Pokemon do you have to a strong rock or ground Pokemon?

You're absolutely right! Rock and Ground-type Pokémon are super effective against Fire-types. This means they do double damage when attacking a Fire-type Pokémon.

Here's why:

* Rock: Rock-type Pokémon have a natural resistance to fire, making them ideal for battling Fire-types.

* Ground: Ground-type Pokémon have a similar advantage due to the fact that fire can't spread underground (think about trying to light a fire under the soil).

So, if you're facing a Fire-type Pokémon, your best bet is to bring out a strong Rock or Ground-type Pokémon!
