Fighting-type weaknesses depend on the system you’re asking about. If you’re referring to Pokémon, Fighting-type moves are weak to Flying, Psychic, and Fairy-type attacks, while Fighting-type Pokémon themselves are commonly vulnerable to Flying, Psychic, and Fairy defenses. If you meant real-world martial arts, “weaknesses” aren’t defined in the same way as game types; effectiveness depends on rules, environment, and matchups rather than a fixed chart. Below are concise breakdowns for the two most common contexts: Pokémon (games)

• Weak to: Flying, Psychic, Fairy
• Common counters against Fighting-types: Flying-type moves (e.g., Acrobatics, Brave Bird), Psychic-type moves (e.g., Psyshock, Psychic), Fairy-type moves (e.g., Dazzling Gleam)
• Strong against: Rock, Ice, Normal, Dark, Steel (these are some of the types that Fighting is effective against)

Real-world martial arts context

• No universal “weakness graph.” Effectiveness is situation-dependent:
  • Range and reach: Strikes can dominate in longer-range styles; close-quarters are often won by grappling-focused arts.
  • Training emphasis: Sports rules, protective gear, and competition formats shape which techniques are practical.
  • Environment: Ground, obstacles, and multiple attackers dramatically change outcomes.
  • Skill and conditioning: Speed, precision, defense, and experience are primary determinants.

If you can specify which system you’re asking about (e.g., Pokémon games, a specific fighting game, or real-world martial arts), the exact weaknesses and counters can be tailored precisely.
