What is the Gen 2 Hidden Power Calculator?
The gen 2 hidden power calculator is a specialized tool for players of Pokémon Gold, Silver, and Crystal. In these Generation 2 games, the move “Hidden Power” (TM10) has a unique property: its Type and Base Power are not fixed. Instead, they are determined by a Pokémon’s intrinsic genetic values, known as “Deter Values” or DVs (the precursor to modern IVs). These DVs range from 0 to 15 for four stats: Attack, Defense, Speed, and Special. This calculator takes those four values and instantly computes the resulting Hidden Power, saving players from complex manual calculations.
Any serious Pokémon trainer from the Johto era should use this gen 2 hidden power calculator. It’s essential for competitive battlers aiming to give their Pokémon a specific type of coverage move. For example, a Fire-type Pokémon like Magmar could get a Grass-type Hidden Power to surprise its Water-type counters. It is also invaluable for breeders who are trying to hatch a Pokémon with the perfect combination of DVs for a maximum power Hidden Power of a specific type. A common misconception is that a Pokémon’s species affects its Hidden Power, but it is determined solely by DVs.
Gen 2 Hidden Power Formula and Mathematical Explanation
The mechanics behind the gen 2 hidden power calculator rely on binary math and specific formulas unique to Pokémon Gold, Silver, and Crystal. The calculations are split into determining the Type and the Base Power.
Hidden Power Type Calculation
The Type is determined by the two least significant bits (LSBs) of the Attack and Defense DVs. The formula is:
Type Index = (Attack DV % 4) * 4 + (Defense DV % 4)
This generates a number from 0 to 15, which corresponds to a specific type. For instance, an index of 8 results in a Fire type. Check out our hidden power type chart for a full list.
Hidden Power Power Calculation
The Base Power, which ranges from 31 to 70, is calculated using the most significant bit (MSB) of all four DVs, plus a value from the Special DV. The formula is:
Base Power = floor( ( (v + w + x + y) * 5 + z ) / 2 ) + 31
| Variable | Meaning | Value | DV Stat |
|---|---|---|---|
v |
Speed DV’s MSB | 1 if Speed DV ≥ 8, else 0 | Speed |
w |
Defense DV’s MSB | 1 if Defense DV ≥ 8, else 0 | Defense |
x |
Attack DV’s MSB | 1 if Attack DV ≥ 8, else 0 | Attack |
y |
Special DV’s MSB | 1 if Special DV ≥ 8, else 0 | Special |
z |
Special DV’s Remainder | Special DV % 4 | Special |
Practical Examples (Real-World Use Cases)
Example 1: Seeking a Max-Power Hidden Power Ice
A trainer wants a Starmie with Hidden Power Ice to counter Dragon-type Pokémon like Dragonite. To get Ice type, the Type Index must be 13. According to the formula, one combination is an Attack DV of 15 (15 % 4 = 3) and a Defense DV of 13 (13 % 4 = 1). `(3 * 4) + 1 = 13`. For maximum power (70), all DVs must be 8 or greater, and the Special DV must be 15 (15 % 4 = 3).
- Inputs: Attack=15, Defense=13, Speed=15, Special=15
- Calculator Output: Hidden Power Ice, 70 Power
- Interpretation: This Starmie would be a top-tier competitive threat, possessing a powerful and surprising coverage move. Using a gen 2 hidden power calculator is the fastest way to verify these DVs.
Example 2: A Randomly Caught Pokémon
A player catches a Jolteon and wants to know what its Hidden Power is. They manage to determine its DVs are not perfect.
- Inputs: Attack=10, Defense=7, Speed=12, Special=9
- Calculator Output: Hidden Power Ground, 53 Power
- Interpretation: The Type Index is `(10 % 4) * 4 + (7 % 4) = 2 * 4 + 3 = 11`, which corresponds to Ground. The power is calculated from the DVs being `(1+0+1+1)*5 + (9%4) = 15+1 = 16`. `floor(16/2)+31 = 8+31 = 39`. Wait, my manual calculation is off. Let’s re-check the formula and values. Attack(10>=8)=1, Defense(7>=8)=0, Speed(12>=8)=1, Special(9>=8)=1. Sum is 3. `(3*5 + (9%4)) = 15 + 1 = 16`. `floor(16/2) + 31 = 8 + 31 = 39`. My manual calculation was correct. Let me re-run the example with different DVs for a better power output. Let’s use: Attack=10, Defense=12, Speed=13, Special=9. The power is `(1+1+1+1)*5 + (9%4) = 20+1 = 21`. `floor(21/2)+31 = 10+31 = 41`. Still low. Let’s try to get 53. We need the first part to be 22. `(x*5+y) = 44 or 45`. Let’s try all high DVs except one. Atk=10, Def=12, Spd=14, Spc=15. Power bits: 1,1,1,1. Special remainder: 3. `(4*5+3)/2+31 = floor(23/2)+31 = 11+31 = 42`. Let’s use the calculator’s logic instead of trying to force it. With Attack=10, Defense=7, Speed=12, Special=9, the power is indeed 39. Let’s adjust the example to reflect that.
- Inputs: Attack=10, Defense=7, Speed=12, Special=9
- Calculator Output: Hidden Power Ground, 39 Power
- Interpretation: Hidden Power Ground provides excellent coverage for an Electric-type like Jolteon, hitting opposing Electric and Rock types. However, with a base power of only 39, it is quite weak. The trainer might decide to seek a different Jolteon with better DVs. This is a perfect scenario where a gen 2 hidden power calculator provides immediate, valuable feedback.
How to Use This Gen 2 Hidden Power Calculator
- Determine DVs: First, you need to find your Pokémon’s DVs. In-game, this is difficult. You can use an online Pokémon stat calculator for Gen 2, which can reverse-engineer DVs if you input your Pokémon’s species, level, stats, and Stat Exp. For emulators, you can often view the values directly.
- Enter DVs: Input the four DV values (Attack, Defense, Speed, and Special) into the corresponding fields in the gen 2 hidden power calculator above. Each must be between 0 and 15.
- Read the Results: The calculator will instantly update. The primary result shows the Hidden Power’s final Type and Base Power. The intermediate values show the calculated HP DV, the Type Index number, and the final power for your reference.
- Analyze and Decide: Use the results to decide if the Hidden Power is useful for your Pokémon’s moveset. A high-power move with a type that covers your Pokémon’s weaknesses is ideal. Using this gen 2 hidden power calculator is a key step in competitive team building.
Key Factors That Affect Gen 2 Hidden Power Results
- Attack DV: This is one of the two most critical DVs, as it directly influences both the Type and Base Power. The last two bits determine part of the type, and the MSB influences power.
- Defense DV: Just as important as the Attack DV, the Defense DV’s last two bits finalize the Hidden Power’s type, and its MSB contributes to the power calculation. A slight change here can completely alter the move.
- Speed DV: While it doesn’t affect the move’s type, the Speed DV is crucial for power. A Speed DV of 7 vs. 8 is the difference between a significant power drop and a step towards maximum power. You’ll often see this trade-off analyzed with a gen 2 hidden power calculator.
- Special DV: This DV has a double impact on power. Its MSB is a key component of the power formula, and its last two bits add a final, smaller value, making a high Special DV essential for achieving the maximum 70 base power.
- DV Parity (Odd vs. Even): The parity of a Pokémon’s DVs also determines its HP DV. While not directly related to Hidden Power’s calculation, it’s a critical component of a Pokémon’s overall viability, which is why our calculator shows it. You can learn more about this at our pokemon crystal iv calculator guide.
- The “8 or higher” Rule: The most significant factor for base power is whether each of the four DVs is 7 or lower, or 8 or higher. To get a high-powered Hidden Power, you almost always need all four DVs to be 8 or greater.
Frequently Asked Questions (FAQ)
- 1. What is the maximum power for Hidden Power in Gen 2?
- The maximum base power is 70. This requires all four DVs to be 8 or higher, and the Special DV to be 15. The easiest way to confirm this is with a gen 2 hidden power calculator.
- 2. Can Hidden Power be a Normal-type move?
- No, Hidden Power can never be Normal (or Fairy, in later generations) type. It can be one of 16 other types.
- 3. How do I find my Pokémon’s DVs in the game?
- There is no in-game judge or checker in Gold, Silver, or Crystal. The most common method is to use an external DV calculator tool by inputting your Pokémon’s stats at a certain level (preferably high, like 50 or 100, with known Stat Exp). Some players also use save file viewers. A pokemon gold silver hidden power guide can provide more details.
- 4. Why did my calculator give me a weak Hidden Power?
- A low base power is the result of one or more DVs being below 8. The power formula is very sensitive to this threshold. Even a single DV of 7 instead of 8 can cause a noticeable drop in power.
- 5. Is it better to have a perfect DV of 15 or a specific DV for a type?
- It’s a trade-off. Sometimes, getting the perfect type (e.g., Hidden Power Fire) requires a Defense DV that isn’t 15. For competitive play, having the right coverage move is often more important than having a perfect Defense stat, but this is a strategic decision. Using a gen 2 hidden power calculator helps you see these trade-offs clearly.
- 6. Does Stat Exp (EVs in later gens) affect Hidden Power?
- No. Stat Exp and EVs affect the final stats of a Pokémon, but the Hidden Power calculation is based purely on the base DVs (0-15), which are like a Pokémon’s genes and do not change.
- 7. Why does the calculator show HP DV?
- In Generation 2, the HP DV is calculated from the other four DVs. It’s a critical part of a Pokémon’s overall stats, so we include it for a complete analysis, even though it doesn’t directly affect the Hidden Power calculation itself. More info can be found on our page about how to calculate hidden power.
- 8. Is a Shiny Pokémon’s Hidden Power different?
- Yes, significantly. In Gen 2, being shiny is tied to having specific DVs (Defense, Speed, and Special must be 10, and Attack can be 2, 3, 6, 7, 10, 11, 14, or 15). This severely limits the possible Hidden Power types and powers a shiny Pokémon can have. All shiny Pokémon will have a Hidden Power of either Grass or Dragon, with a power of 49 or 68.
