Here's the breakdown of Fighting type moves and their effectiveness:
Strong Against (Super Effective):
* Normal
* Rock
* Steel
* Ice
* Dark
Weak Against (Not Very Effective):
* Flying
* Poison
* Psychic
* Bug
* Fairy
Immune to (No Effect):
* Ghost
So, when a Fighting Pokémon uses a Fighting type move:
* It will deal more damage to Normal, Rock, Steel, Ice, and Dark type Pokémon.
* It will deal less damage to Flying, Poison, Psychic, Bug, and Fairy type Pokémon.
* It will have no effect on Ghost type Pokémon.
Remember, this is just the effectiveness of Fighting type moves. Individual Fighting Pokémon may have different strengths and weaknesses due to their other types or abilities.
