What is {primary_keyword}?

The {primary_keyword} is a tool that determines how effective each attacking Pokémon type is against a specific Pokémon based on its primary and optional secondary type. Trainers use it to plan battles, choose moves, and build balanced teams. Common misconceptions include thinking that a Pokémon with two types always has double weaknesses; in reality, multipliers combine multiplicatively, which can result in neutral (1×) outcomes.

{primary_keyword} Formula and Mathematical Explanation

Each attacking type has a base multiplier against a defending type: 2× for super‑effective, 0.5× for not very effective, and 0× for no effect. When a Pokémon has two types, the overall multiplier is the product of the two individual multipliers.

Formula:

Overall Multiplier = Multiplier(Attack vs Primary) × Multiplier(Attack vs Secondary)

If the secondary type is “None”, the second multiplier is 1.

Variables Table

Variable Meaning Unit Typical Range
Attack Attacking Pokémon type Type name All 18 types
Primary Defending Pokémon primary type Type name All 18 types
Secondary Defending Pokémon secondary type Type name or “None” All 18 types or None
Multiplier Effectiveness factor × 0, 0.5, 1, 2

Practical Examples (Real-World Use Cases)

Example 1: Charizard (Fire/Flying)

Inputs: Primary = Fire, Secondary = Flying

Result: Weak to Water (2×), Rock (4×), Electric (2×). Resistant to Grass (0.5×), Bug (0.25×), Steel (0.5×). No immunities.

Example 2: Gengar (Ghost/Poison)

Inputs: Primary = Ghost, Secondary = Poison

Result: Weak to Ground (4×), Psychic (2×), Dark (2×). Resistant to Poison (0.5×), Bug (0.5×), Grass (0.5×), Fairy (0.5×). Immune to Normal (0×) and Fighting (0×).

How to Use This {primary_keyword} Calculator

  1. Select the Pokémon’s primary type from the dropdown.
  2. If the Pokémon has a secondary type, select it; otherwise leave “None”.
  3. The results update automatically, showing the most damaging type, a full list of multipliers, and a visual chart.
  4. Use the “Copy Results” button to copy the summary for sharing or note‑taking.
  5. Refer to the intermediate values to understand each type’s exact multiplier.

Decision‑making guidance: Prioritize moves of types that have a 2× or 4× multiplier against your opponent, and avoid using types that are resisted or immune.

Key Factors That Affect {primary_keyword} Results

  • Primary Type: Determines the base interaction with attacking types.
  • Secondary Type: Modifies the multiplier multiplicatively, potentially creating double weaknesses or neutralizing them.
  • Generation Mechanics: Some type interactions changed across game generations (e.g., Fairy type added in Gen 6).
  • Ability Effects: Abilities like “Levitate” can grant temporary immunities, altering effective results.
  • Weather Conditions: Certain weather (e.g., “Rain”) can boost Water‑type moves, effectively increasing damage beyond the base multiplier.
  • Item Modifiers: Items such as “Expert Belt” increase damage from super‑effective moves by 20%.

Frequently Asked Questions (FAQ)

What if a Pokémon has only one type?
The secondary multiplier defaults to 1, so the overall multiplier equals the primary interaction.
Can a type have a 4× weakness?
Yes, when both primary and secondary types are each weak to the same attacking type (e.g., Rock vs Fire/Flying).
Do abilities change the {primary_keyword} output?
The calculator shows base type interactions; abilities that grant immunity or boost damage are not included but can be considered separately.
Why does the chart sometimes show 0.25×?
When both types resist the same attacking type, the multipliers multiply (0.5 × 0.5 = 0.25).
Is the “None” option required for secondary type?
Yes, it ensures the calculator treats single‑type Pokémon correctly.
How often are type charts updated?
Official type charts have been stable since Generation 6, with only minor adjustments in later games.
Can I use this calculator for Pokémon in different generations?
The base type effectiveness is consistent across generations; however, generation‑specific abilities or moves may affect real battle outcomes.
Is there a way to export the chart?
Use the browser’s “Save image as…” on the canvas to download the chart.
