Bug Type Weakness

Bug type weakness: Fire, Flying and Rock moves deal 2× damage to the Bug type. Scizor and Forretress (Bug/Steel) have exactly one weakness: Fire, at 4×. Shedinja (Bug/Ghost) has five, Fire, Flying, Rock, Ghost and Dark, and its Wonder Guard ability blocks most other damaging moves. Status moves and indirect damage still work on it.

Rules & history

Bug type rules beyond the chart

Battle effects tied to the Bug type, and what was different in older games.

Beyond the chart

  • U-turn and Sticky Web
    U-turn hits and then switches the user out. Sticky Web (Gen 6+) drops the Speed of grounded foes by one stage as they switch in.
  • Stealth Rock: 25% on switch-in
    Bug is weak to Rock, so Stealth Rock takes twice the usual 12.5% of max HP. Heavy-Duty Boots (Gen 8+) block it.

How Bug changed across generations

  1. GEN2Gold & SilverBug moves lost their 2× on Poison and now do ½ damage, and Poison moves hit Bug for normal damage instead of 2×.
  2. GEN4Diamond & PearlSince Gen 4, each Bug move is physical or special based on the move itself. Before that, every Bug move was physical.
  3. GEN6X & YFairy type added. Bug moves do ½ damage to Fairy.
