FightingDragon
Fighting and Dragon types: weaknesses, resistances and Pokémon
Fighting and Dragon Pokémon take quadruple damage from Fairy moves, take double damage from Ice, Flying, Psychic and Dragon moves and resist Fire, Water, Grass, Electric, Bug, Rock and Dark moves.
The balance is even: 5 weaknesses and 7 resistances or immunities.
Fighting moves are super effective against Normal, Ice, Rock, Dark and Steel and not very effective against Poison, Flying, Psychic, Bug and Fairy. Dragon moves are super effective against Dragon and not very effective against Steel.
To beat these Pokémon, your best pick is Fairy moves. Avoid Fire, Water, Grass and Electric moves, which deal little or no damage.
There are 3 Pokémon with this combination, such as Hakamo O, Kommo O and Koraidon.
