Nidoqueen is a good one.
Flying and Psychic do 2x damage to Fighting-type Pokemon.
Fire/fighting type pokemon are good . such as pokemon in the charmander family
Fighting type is good against normal type, please come to me if you have any other type match ups that you want. I can also (based on the game you are playing) tell you where to get that type of pokemon.
Fighting type, ground type
The fighting type is weak against Ghost and Dark Pokemon, so a Sableye would be good.
Unfortunately, fighting Pokemon are not super-effective against dragon-type Pokemon. However, if the fighting-type (move or Pokemon) is strong enough, it can still do substantial damage against a dragon-type Pokemon.
the pokemon good against fighting are: flying ground fire (I think)
Ice type pokemon.
Fighting type pokemon are weak against psychic attacks
A fire and a fighting type Pokemon is good against steel.
Generally, Fire-type Pokémon are not good against Fighting-type Pokémon. Find a Fire-type Pokémon that can learn Ground- or Psychic-type moves, such as Earthquake or Psychic, since those are super effective on Fighting-type Pokémon.
machamp is good, hitmonlee, mankey and primape are good to
