Pokémon Stats Guides
Pokémon have several hidden stats, let's just go through the ones we can see on the stats page.
HP (hit points) is related to how much damage a Pokemon can sustain before fainting.
CP (combat power) is not related to how much damage a Pokemon deals when attacking gyms, but is a combination of attack, defense, and stamina (HP). If a Pokémon would have less than 10 CP, it has 10 instead.
Height and weight, despite all the rumors that they affect gameplay, are purely cosmetic and have no gameplay impact (other than the Fisherman and Youngster medals).
The blue glow that appears behind Pokémon in your storage mean that you caught it in the last 24 hours.
Note that evolving a Pokémon retains the same relative value for HP and CP that increase by a species-specific ratio because their underlying hidden stats (IVs) don't change, whereas height and weight are randomized from scratch.
Pokémon "Levels" and Max Level
Pokémon have a semi-hidden stat called a "level".
The white semicircle above them on their stats page shows their progress from minimum level (level 1 on the left side) to a maximum based on the player's level. Every time a Pokémon powers up they gain 1/2 a level and some amount of CP, and the white dot moves farther to the right end.
If it reaches the end (and the trainer is not yet at least level 40), it will say that the trainer needs to increase their trainer level to power up further (and thus allow the Pokémon to level up more, thereby gaining more CP). This is because a Pokémon's level is not allowed to exceed a trainer's level + 2 with a few variables.
If the trainer is Lv.1-38, then the maximum level of a Pokemon is the trainer's level +2, meaning the maximum is 40.
If the trainer is Lv.38 or 39, then the cap remains at Lv.40
If the trainer is Lv.40-50, then the level cap of the Pokemon is 50.
Powering up costs both Stardust and candies or XL candies if Lv.40 or over specific to that Pokémon type (or by using Rare Candy that acquired from defeating Raid Bosses). When it is powered up, the Pokémon gains CP following a complicated formula, gaining more CP the better its hidden stats are.
Whenever a Pokémon is powered up, its level increases by 1/2. A Pokémon at the minimum possible CP is at level 1. To calculate a Pokémon's level, divide its current CP by how much CP it gains per power up, and then divide that again by 2.
Every 2 levels (or 4 power ups), the Stardust cost of powering up increases. Every 10 levels (or 20 power ups), the candy cost of powering up increases by 1. Note that since level determines Stardust cost, it is possible for a lower CP Pokémon to cost more to upgrade since it can gain less CP per level and thus have a lower max CP cap.
Don't forget, a Pokémon cannot be powered up past a trainer's level + 2. And even if a trainer achieves max trainer level, the only way to get the most powerful Pokémon is to find one with perfect hidden stats called Individual Values (IVs), which will be covered more in the advanced stats article.
Every Pokémon has a random Fast move and a random Charge move that is chosen from a list of valid moves. The Fast move is a weaker attack that the Pokemon will use freely. The Charge move usually deals more damage but must be charged to a point in order to be used.
In raids, a charged move will take 33, 50, or 100 energy to execute, with the maximum energy storage being 100. Charged moves are ready to used when their icons fully fill with color on the raid screen.
Every move also has a hidden attack speed, and generally lower damage moves have faster attack speeds.
Using Fast moves and Charge moves that are the same type as the Pokémon gives a 1.2x damage multiplier called same type attack bonus (STAB).
Note that evolving a Pokémon randomizes its moveset.
Evolving tends to cost a large number of candies, but no Stardust. It also grants the trainer 1 candy for the Pokemon species evolved.
When a Pokémon evolves, its base stats change so the displayed HP and CP increase. However, its Pokémon level and IVs do not change, so when a naturally powerful basic Pokémon is evolved, its evolution will also be naturally powerful.
Hidden Stats and IVs
Pokémon have the following hidden core stats, similar to the games:
Each has a base value (predetermined by species) and an individual value (IV) that is added on top of the base value and ranges from 0–15. To have a truly maxed out Pokémon requires acquiring one with maxed out IVs.
