If you’ve ever jumped onto the Battle Stadium Singles ladder or entered a VGC tournament only to find your Pokémon getting outsped and knocked out by the exact same species you’re using, you aren’t alone. It feels like a glitch in the Matrix. Your Garchomp and their Garchomp are both Level 50. You both used Earthquake. So why did their Garchomp move first and hit significantly harder?
The answer lies in the "Hidden Numbers" of Pokémon. While the games have become much more transparent about these systems in recent generations (specifically Pokémon Scarlet and Violet), there is still a layer of complexity that separates a casual playthrough from a competitive masterclass. To truly understand your Pokémon’s potential, you must master the Trinity of Pokémon Stats: Individual Values (IVs), Effort Values (EVs), and Natures.
By the end of this guide, you won’t just know what these terms mean; you’ll know how to manipulate them to turn a "room temperature" team into a heat-seeking missile.

Individual Values (IVs): The Genetic Code
Think of IVs as a Pokémon’s DNA. Just as some humans are naturally taller or have faster reflexes from birth, every Pokémon is born (or caught) with a set of innate potential markers for each of its six stats: HP, Attack, Defense, Special Attack, Special Defense, and Speed.
How IVs Work Every stat has an IV ranging from 0 to 31. An IV of 0 means that stat is as low as it can possibly be for that species. An IV of 31—often called a "Perfect" IV or "Best"—means the stat is at its maximum genetic potential.
At Level 100, each IV point translates directly to one stat point. If you have two Charizards with the exact same personality and training, but one has a 0 IV in Speed and the other has a 31 IV, the latter will have 31 more points in its Speed stat. In a game where moving first is often the difference between winning and losing, those 31 points are an eternity.
The Myth of "All 31s" While you generally want 31 IVs in every stat, there are two major exceptions where a 0 IV (often called "No Good" in the in-game judge tool) is actually superior: 1. Special Attackers and Confusion/Foul Play: The move Foul Play and the self-inflicted damage from Confusion are calculated based on your Pokémon's physical Attack stat. If you are using a Gholdengo or a Flutter Mane, you want your Physical Attack IV to be 0 to minimize the damage you take from these sources. 2. Trick Room Teams: In the "Trick Room" field effect, the slowest Pokémon moves first. Competitive players often hunt for a "0 Speed" IV on Pokémon like Ursaluna or Torkoal to ensure they are the fastest things under Trick Room.
How to Fix Them: Hyper Training In the old days, getting perfect IVs required hundreds of hours of breeding. Today, we have Bottle Caps. Once a Pokémon reaches Level 50, you can take it to an NPC in Montenevera (in Scarlet/Violet) to participate in Hyper Training. This effectively "masks" your low IVs, bumping them up to the equivalent of 31. Note that this doesn't change the actual genetics for breeding purposes, but for battling, it’s a game-changer.

Effort Values (EVs): The Result of Hard Training
If IVs are genetics, EVs are the gym sessions. Effort Values represent the training your Pokémon receives. Unlike IVs, which are set at birth, EVs are completely under your control.
The Math of EVs A Pokémon can have a grand total of 510 EV points. A single stat can have a maximum of 252 EV points. At Level 100, 4 EV points = 1 Stat Point*.
This means you can "max out" two stats (252 + 252 = 504) and have 6 points left over to dump into a third stat.
The Logic of Distribution How you distribute these points depends entirely on the Pokémon’s role. Let's look at a classic example: Flutter Mane. The Glass Cannon Route: You put 252 into Special Attack and 252 into Speed. You want it to hit as hard and as fast as possible. The Bulky Route: You might put 252 into HP and some into Defense to help it survive a hit from a physical priority move like Dragonite’s Extreme Speed.
How to Earn EVs 1. Battling: Every Pokémon you defeat in the wild or in a trainer battle yields specific EVs. Defeating a Chansey gives HP EVs; defeating a Floatzel gives Speed EVs. 2. Power Items: If your Pokémon holds a Power Bracer or Power Lens, they gain extra EVs in a specific stat every time they win a battle. 3. Vitamins: This is the "rich player" method. Using items like Protein, Iron, and Carbos grants 10 EV points per bottle. In modern games, you can max out a Pokémon’s EVs in seconds if you have enough PokéDollars. 4. Feathers: Items like the Muscle Feather or Swift Feather give exactly 1 EV point. These are perfect for "fine-tuning" a stat spread when you don't want to go all the way to 252.
Resetting EVs Made a mistake? In The Teal Mask DLC, you can use Fresh-Start Mochi to wipe a Pokémon's EVs clean. Alternatively, certain berries (like Pomeg or Kelpsy berries) reduce EVs by 10 points while increasing friendship.

Natures: The Personality Modifier
Natures are the final piece of the puzzle. Every Pokémon has one of 25 possible Natures. Most Natures do two things: they increase one stat by 10% and decrease another stat by 10%.
Why 10% Matters A 10% boost might not sound like much, but on a Pokémon with a high base stat, it is massive. Take Baxcalibur. At Level 100 with max EVs, an Adamant Baxcalibur (which boosts Attack and lowers Special Attack) has an Attack stat of 427. If it had a Modest nature (which lowers Attack), that stat would drop to 349. That’s a 78-point difference!
Common Competitive Natures Specific Natures dominate the competitive scene because they maximize a Pokémon’s strengths while sacrificing a stat they don't use: Adamant (+Atk, -SpAtk): For physical attackers like Palafin or Roaring Moon. Modest (+SpAtk, -Atk): For special attackers like Gholdengo. Jolly (+Speed, -SpAtk): For physical attackers that need to be fast, like Meowscarada. Timid (+Speed, -Atk): For special attackers that need to be fast, like Iron Valiant. Bold (+Def, -Atk): For physical walls/supports like Amoonguss. Impish (+Def, -SpAtk): For physical tanks that still want to hit hard, like Great Tusk.
Mints: Nature Without the Trauma In older games, if you caught a Shiny Pokémon with a "Relaxed" Nature but wanted it to be "Jolly," you were out of luck. Now, we have Mints. A Jolly Mint won't change the name of the Nature on the summary screen, but it will change the stat bonuses to match the Jolly profile. Look for the blue and red arrows in your stat hexagon: Red is increased, Blue is decreased.

Bringing it All Together: The Garchomp Scenario
Let’s revisit our intro. Why did your Garchomp lose to the opponent's?
Your Garchomp: IVs: Decent (20 Speed IV) EVs: Randomly distributed from playing through the story (100 HP, 50 Attack, 40 Defense, etc.) Nature:* Careful (+SpDef, -SpAtk) — Not helpful for Speed or Damage.
Opponent’s Garchomp: IVs: Perfect (31 Speed IV via Hyper Training) EVs: Fully optimized (252 Attack / 252 Speed / 4 HP) Nature:* Jolly (+Speed, -SpAtk)
Even though both are Level 50, the opponent's Garchomp might have a Speed stat of 169, while yours might be hovering around 125. They will always move first, and because they have 252 Attack EVs and a positive Nature, their Earthquake will deal significantly more damage than yours.
How to Optimize a Pokémon in 3 Steps If you want to take a Pokémon from "Casual" to "Competitive," follow this checklist: 1. Check the Nature: Use a Mint to ensure the 10% boost is in the right place (usually Speed or your primary attacking stat). 2. EV Train: Buy 26 Vitamins for your primary stat and 26 for your secondary stat (e.g., 26 Proteins and 26 Carbos). This will max them out. 3. Hyper Train: Go to Montenevera with Bottle Caps and max out the IVs for HP, Attack (or Sp. Atk), Defense, Sp. Defense, and Speed.

Advanced Tip: Speed Creeping and Survival Benchmarks
Once you understand the basics, you can move into "Advanced EV Spreads." Most pro players don't just go 252/252/4. Instead, they calculate exactly how many EVs they need to survive a specific hit.
Example: Incineroar in VGC An Incineroar player might realize that with 156 EVs in Defense, they can always survive a Surfing strike from a Choice Spec-boosted Urshifu-Rapid Strike. They put the rest of their points into HP and Attack. This is called benchmarking.
Similarly, "Speed Creeping" involves putting just enough EVs into Speed to be 1 point faster than a specific threat. If you know most people run their Gholdengo at a certain speed, you might put enough EVs to reach that number plus one, allowing you to get the KO before they can touch you.

Final Thoughts
The jump from casual play to competitive Pokémon can feel like learning a new language, but IVs, EVs, and Natures are the grammar that makes the whole thing work. By mastering these three systems, you stop relying on luck and start relying on math and strategy.
You don’t need to be a human calculator to enjoy this level of play. Start by using Mints and Vitamins on your favorite Pokémon, and observe the difference in the next Tera Raid or ranked match. Once you see your "slow" Pokémon suddenly outspeeding the competition, there’s no going back. Welcome to the big leagues.
