Types: the first identity card
The type is a Pokémon's most visible property. There are eighteen of them (Normal, Fire, Water, Grass, Electric, Ice, Fighting, Poison, Ground, Flying, Psychic, Bug, Rock, Ghost, Dragon, Dark, Steel, Fairy). A Pokémon has a single type (Charmander is pure Fire) or a combination of two types (Bulbasaur is Grass / Poison).
The type defines two things: which moves hit it for bonus or reduced damage (the famous type chart), and the power boost a Pokémon gets for using a move that matches its own type, called STAB. Mastering these interactions is the heart of Pokémon strategy.
Because the subject deserves a full treatment, we dedicate an entire article to it: see the type guide for the detailed effectiveness chart, immunities and the best defensive combinations.
The six base stats
Every Pokémon is defined by six base stats, which are the canonical values of the species and never change from one individual to another:
- HP (Hit Points): how much damage it can take before fainting.
- Attack: the power of physical moves (Body Slam, Rock Slide...).
- Defense: resistance to incoming physical moves.
- Special Attack: the power of special moves (Flamethrower, Surf...).
- Special Defense: resistance to incoming special moves.
- Speed: determines who acts first in a turn.
The split between physical and special is a cornerstone of the game: a Pokémon can be a wall in Defense but a sieve in Special Defense, like Steelix, and the opponent will always look for the weak side. The spread of these six values shapes the creature's natural role, which is exactly what you learn to read in the Guess the Stats quiz.
BST and battle roles
The BST (Base Stat Total) is the sum of all six base stats. A small early-game Pokémon sits around 300, a fully evolved Pokémon between 480 and 540, and the elite (pseudo-legendaries and legendaries) reaches 600 or more. BST gives a rough sense of power, but the distribution matters just as much as the total.
Depending on how those points are spread, a Pokémon takes on a role:
- Fast sweeper: very high Speed and one offensive stat, weak defenses. It hits hard and fast but does not last. Think Charizard or Weavile.
- Wall: huge HP and defenses, weak offense. It tanks, stalls and grinds the opponent down. Steelix, defensive Gyarados, Skarmory.
- Tank: a compromise between bulk and offense, able to endure while still dealing damage. Snorlax, Venusaur.
- All-rounder: balanced stats with no extreme, flexible but a master of none.
Understanding the role helps you anticipate: a very fast Pokémon will try to end the fight before being touched, a wall will try to drag it out.
IVs, EVs and Natures: what sets two individuals apart
Two Pokémon of the same species share the same base stats, yet can end up with different numbers, because of three hidden mechanics.
IVs (Individual Values) are the genetic part: each stat gets a random number from 0 to 31, locked in when you encounter the Pokémon. One with 31 IVs everywhere is called perfect. This is precisely what IV calculators reverse-engineer from the displayed stats.
EVs (Effort Values) are the training part: by defeating Pokémon or using certain items, you gain EVs in specific stats. The cap is 510 EVs total, with a maximum of 252 per stat, letting you specialize a Pokémon into its chosen role.
The Nature, finally, is a personality trait (Adamant, Modest, Timid...). Most Natures raise one stat by 10 % and lower another by 10 %. You therefore pick a Nature that boosts the role's key stat and cuts a useless one, for example Timid (Speed up, Attack down) for a fast special attacker.
Evolution stages and methods
Most Pokémon belong to an evolution line that can have up to four links:
- Baby: a pre-evolution obtained through breeding (Pichu, Cleffa, Smoochum).
- Base: the first stage met in the wild (Pikachu, Charmander).
- Stage 1: the first evolution (Raichu, Charmeleon).
- Stage 2: the final form (Charizard, Blastoise).
The evolution trigger varies enormously by species:
- Level: the classic method, reaching a threshold (Charmander evolves at level 16).
- Evolution stone: Fire Stone, Water Stone, Thunder Stone, Moon Stone, and so on.
- Trade: some only evolve when traded between games (Haunter, Machoke), sometimes while holding an item.
- Friendship: a high level of affection (Eevee into Espeon by day, Umbreon by night).
- Held item: evolving while holding a specific item during a trade or level-up.
- Location: evolving near a particular place, such as a special cave.
- Time of day: day or night influences certain evolutions.
Recognizing which stage a silhouette belongs to is exactly the exercise of the Silhouette quiz, where posture often gives away the link in the chain.
Alternate forms
A single species can exist in several forms, sometimes with completely different types and stats.
- Regional forms: a Pokémon adapted to a region, with a new look and often new types. They include the Alolan forms (Alolan Vulpix, Ice), Galarian forms (Galarian Meowth, Steel), Hisuian forms (Hisuian Arcanine, Fire / Rock) and Paldean forms (Paldean Tauros).
- Mega Evolutions: a temporary in-battle transformation, triggered by a Mega Stone, that strongly boosts stats and sometimes changes the type (Mega Charizard X becomes Fire / Dragon).
- Gigantamax: a Galar-specific phenomenon where the Pokémon becomes giant for a few turns and gains an exclusive G-Max move.
These forms deliberately scramble your reference points: an Alolan Vulpix shares nothing type-wise with a Kanto Vulpix. It is a classic trap in our quizzes, where the form changes the expected stat profile.
Shiny Pokémon
A Shiny Pokémon is an extremely rare color variation. Its stats, type and abilities are strictly identical to the normal version: only the palette changes, sometimes subtly, sometimes dramatically (a red Gyarados instead of blue).
In recent games, the base chance of meeting one is around 1 in 4096, lowerable through various hunting methods. A Shiny therefore grants no combat advantage: it is a collector's trophy, a sign of patience and luck, with zero impact on the species' technical sheet.
Special categories
At the top of the Pokédex, some creatures stand apart through their rarity and power.
- Legendaries: unique Pokémon, central to each region's mythology (Articuno, Dialga, Zacian). Often a single specimen per playthrough, with very high stats.
- Mythicals: even rarer, usually distributed during special events (Mew, Celebi). They are not found in the game through normal means.
- Ultra Beasts: creatures from another world, the Ultra Space, introduced in the seventh generation (Nihilego, Buzzwole). Their stat profiles are often extreme and lopsided.
- Pseudo-legendaries: non-legendary Pokémon with a BST of 600, at the top of a classic line, with a late and powerful final evolution (Dragonite, Metagross, Garchomp, Gigalith...). They are the elite reachable through normal capture.
Telling these categories apart helps you guess a Pokémon from a BST of 600 or an off-the-charts stat in the Guess the Stats quiz, or to place an entry in the Pokédex quiz.
The Ability, the finishing touch
Beyond stats and types, every Pokémon has an Ability, a passive trait that triggers automatically (Intimidate lowers the opponent's Attack on entry, Levitate cancels Ground moves, Drought sets up harsh sunlight). A species has one or two regular Abilities and, often, a rarer Hidden Ability.
An Ability can redefine a Pokémon's role entirely, sometimes more than its raw stats do. It is a full dimension of a Pokémon's anatomy: we dedicate the Ability guide to understanding the most impactful ones and how to exploit them.
