Defensive Matchup
Every Pokémon battle comes down to type matchups. Choosing the right move can mean the difference between victory and defeat. A Pokémon Weakness Calculator helps trainers quickly find out which types a Pokémon is weak to, resistant to, or completely immune against.
Whether you’re battling online, facing a Gym Leader, or preparing for competitive play, knowing weaknesses instantly gives you the winning edge.
🔍 What is a Pokémon Weakness Calculator?
A Pokémon Weakness Calculator is a tool that shows how much damage a Pokémon takes from different attack types. You just enter a Pokémon or select its typing, and the calculator instantly displays:
- Weaknesses (2× or 4× damage)
- Resistances (0.5× or 0.25× damage)
- Immunities (0× damage)
This way, you know which moves to avoid and which opponents can counter your Pokémon.
📊 Pokémon Weakness Table Example
Here’s a simplified version of how type weaknesses look:
| Pokémon Type | Weak Against (2×) | Resistant To (0.5×) | Immune To (0×) |
| Fire | Water, Rock, Ground | Fire, Grass, Ice, Bug, Steel, Fairy | — |
| Water | Electric, Grass | Fire, Water, Ice, Steel | — |
| Flying | Electric, Ice, Rock | Grass, Fighting, Bug | Ground |
| Ground | Water, Grass, Ice | Poison, Rock | Electric |
| Ghost | Ghost, Dark | Poison, Bug | Normal, Fighting |
(This is a short version; a full chart covers all 18 Pokémon types.)
🧮 Formula for Weakness Calculation
The weakness calculator uses the standard type effectiveness formula:
Damage Multiplier=∏(Type Effectiveness)\text{Damage Multiplier} = \prod (\text{Type Effectiveness})Damage Multiplier=∏(Type Effectiveness)For single-type Pokémon, it’s straightforward (e.g., Fire takes 2× from Water).For dual-type Pokémon, multipliers stack.Example: Charizard (Fire/Flying) vs. Rock attack → 2× (Fire weak to Rock) × 2× (Flying weak to Rock) = 4× weakness.
