Pok-mon Type Coverage Calculator: Gen 9 Battle Guide
Victory in competitive Pok-mon battles like VGC or Smogon is about synergy over raw power. I built this Type Coverage Calculator to help you identify 4x weaknesses and pivot opportunities. Mastering the type chart is the difference between being a casual trainer and a top-tier strategist.

How Do You Check Team Effectiveness?
Advanced Type Coverage Strategy
Competitive Pok-mon isn't just about knowing that Fire beats Grass; it's about understanding Defensive Cores and Offensive Coverage gaps. For example, the famous "Regenerator Core" often relies on types that resist each other's weaknesses. If you have a Poison-type like Toxapex, you want a teammate that can switch into the Ground and Psychic moves that threaten it. This tool allows you to plug in potential teammates and see if your team has a "shared weakness" that a single opponent could exploit to sweep your entire squad.
Dual-Type Matchup Examples: The Math of Meta
Understanding dual-type chemistry is the hallmark of a Pro trainer. Generation 9 (Scarlet & Violet) has introduced complex new threats that require precise calculation. Here are three examples of how this tool computes multipliers for the current competitive meta:
1. The Scizor Trap (Bug/Steel)
Scizor is famous for having only one weakness, but it's a massive one. This is why trainers often use a Fire-resistant teammate to pivot.
- Type 1 (Bug): Weak to Fire (2x)
- Type 2 (Steel): Weak to Fire (2x)
- Math: 2 (Bug) × 2 (Steel) = **4x Weakness**
- Strategy: One Fire move will likely OHKO (One-Hit Knockout) Scizor regardless of its health.
2. The Kingambit Wall (Dark/Steel)
Kingambit is a powerhouse in Gen 9, but its dual typing makes it extremely vulnerable to Fighting moves.
- Type 1 (Dark): Weak to Fighting (2x)
- Type 2 (Steel): Weak to Fighting (2x)
- Math: 2 × 2 = **4x Weakness**
- Note: While it resists 9 types, a single 'Close Combat' can end its sweep instantly.
3. The Spiritomb Shadow (Ghost/Dark)
Before the introduction of Fairy types in Gen 6, this combination was legendary for having zero weaknesses.
- Fairy vs Ghost: 1x (Neutral)
- Fairy vs Dark: 2x (Weak)
- Result: 2x Weakness to Fairy. It remains immune to Normal, Fighting, and Psychic moves.

What is the Math of Matchups (1x to 4x Damage)?
Damage calculation in Pok-mon is a multiplicative process. When a dual-type Pok-mon is hit, the game checks the effectiveness against both types separately and then multiplies those values together. This is where 4x weaknesses come from, and it's as critical to understand as a percentage increase in your business revenue.
Multiplier outcomes include:
- 0x (Immunity): The move does no damage (e.g., Ground vs Flying).
- 0.25x (Double Resistance): Both types resist the move.
- 0.5x (Resistance): One type resists while the other is neutral.
- 1.0x (Neutral): The types cancel out or both are neutral.
- 2.0x (Weakness): One type is weak.
- 4.0x (Double Weakness): Both types are weak.
Offensive Move Coverage Strategy
While defensive typing is about survival, Offensive Coverage is about ensuring your moves hit at least neutrally (1x) against the entire meta. I always recommend the "Bolt-Beam" strategy (Electric and Ice moves). Because very few Pok-mon resist both Electric and Ice, having this combo ensures you are rarely stuck in a "Not Very Effective" situation. Competitive players use my tool to check for "Gaps" in their team's offensive pressure.
Terastallization: Solving Your Biggest Weakness
Generation 9 introduced **Terastallization**, a mechanic that allows any Pok-mon to change into a single "Tera Type" once per battle. This effectively resets your defensive profile. If you have a Dragon/Ground Garchomp terrified of Ice-beams, you can Tera into **Steel** to resist that Ice move perfectly.
This calculator is perfect for "Simulating Tera Shifts." Input a single type in our tool to see how your defensive profile changes after clicking the Tera button in-game.
The Impact of the Fairy Type
The introduction of the Fairy type in Generation VI was one of the most significant balance shifts in Pok-mon history. Before Fairy types, Dragon types were notoriously difficult to counter, as their only weaknesses were Ice and other Dragon moves. By making Fairy immune to Dragon and super-effective against it, Game Freak successfully curtailed the "Dragon dominance." This tool allows you to see how contemporary Fairy-types like Zacian or Flutter Mane match up against the traditional titans of the meta.
Pok-mon Battle Strategy FAQ
What Pok-mon type has the most resistances?
Steel is the king of defense with 10 resistances and 1 immunity (to Poison). It is often the core of competitive teams because it can switch safely into almost any non-offensive threat.
What is 'STAB' damage in Pok-mon battles?
STAB (Same Type Attack Bonus) grants a 1.5x damage multiplier to any move that matches your Pok-mon's current typing. If you are a Fire type using 'Flamethrower', you do 50% more damage than a non-Fire type using it.
Can a Pok-mon be immune to two or more types?
Yes. A **Ghost/Dark** type like Sableye or Spiritomb is immune to Normal, Fighting, and Psychic moves (3 full immunities). This profile makes them incredible wall-breakers and stallers.
What is a 4x weakness move?
A 4x weakness occurs in dual-type Pok-mon when both of their types are weak to the same move. For example, Scizor is Bug/Steel, and both are weak to Fire, resulting in 4x damage multiplier. It is almost always a One-Hit Knockout (OHKO).
How does Terastallization affect weaknesses?
Terastallization changes a Pok-mon to its single Tera Type, completely resetting its defensive profile for the remainder of the battle. It is the ultimate defensive card to turn a 4x weakness into a resistance.
