Stats are one of the most important things in the Pokémon games. If you have a Pokémon with great attacks, yet not so good stats, you are destined to lose the battle, even if you have type advantages. As such, this page is to help you understand the way stats are calculated, what affects them and how to boost them and hinder your opponents. There are six stats in total that you can fully manipulate and two alternate stats which always have a set value at the beginning of the battle, until they get affected by attacks that is. There are many ways in which the stats are determined;

Base stats are the core of the whole stats. Each Pokémon species has their own unique set of base stats. These stats help determine the total stats when the Pokémon is at a specific level. However, as each species has a different, this means that if say you have two Meganium, their stats will not be radically different if untrained.

Individual Values are a specific value that each Pokémon has one each of its six stats. The value ranges from 0 to 31 and each value corresponds to one single stat point at Level 100. Technically, apart from seeing their effect, they are a hidden value which you have little to no control over. If you have a Pokémon with a high IV, you will have the ability to pass it down via breeding, however that means is pretty much random. As there are six stats and thirty one possible values for each stat, there are 1,073,741,824 different IV combinations making sure that you will pretty much never have a Pokémon exactly the same as another one of the same species. To calculate IVs, use our IV Calculator.

Effort Values are another set of values utilised to determine a Pokémon's stat. However, unlike IVs and Base Stats, EVs are totally customisable. You earn Effort Values by battling Pokémon, with each Pokémon giving a different set of EVs to the Pokémon that defeats it. For every 4 EVs earned in a particular stat, you get 1 extra stat point at Level 100. However, there are limits on the Effort Values you can have. You can only have 510 Effort Values on any one Pokémon, corresponding to a maximum of 255 on two stats. However, as that is not divisable by four, it's best to take it to 252 when maxing a stat. This corresponds to 63 more stat points at Level 100. The dispersal of these values is completely up to you so it can help you make the most out of your Pokémon.

The Level of your Pokémon is also vital in the calculation of the Pokémon stats. As you increase in level, the stats get increased by 2% of the Base Stat value and 1% of the combined IV and current EV value. This means that even if you have maxed out a stat in EVs but it's still say Level 10, you'll only notice a minimal stat increase.

Finally, Natures are the other attribute which have a permanent affect on the stats. Each nature raises one stat while lowering another (the neutral natures raise and lower the same stat rendering them inert). At the end of the calculation, the nature is taken into account. If it raises the stat, then the stat's value becomes 110% of what it would normally be and if it lowers the stat, the value becomes 90% of what it would normally be

This is how the stats are calculated;

Hit Points:
           ( (IV + 2 * BaseStat + (EV/4) ) * Level/100 ) + 10 + Level

Attack, Defense, Speed, Sp. Attack, Sp. Defense:
           (((IV + 2 * BaseStat + (EV/4) ) * Level/100 ) + 5) * Nature Value

In battles, a Pokémon's stats are able to be modified, both positively and negatively, for the duration of the Pokémon in battle. There are several ways in which these are boosted/lowered; By Attack, by Item or by Ability. When the specific attack or item is used, the stats go up or down by a number of stages, usually by one stage, sometimes by two and on some occassions, by even more. There are 13 total stages in which the stat can hold and once it reaches the top or the bottom, it cannot be increased or lowered any further respectively. At the start of battle or when the Pokémon is switched in, the value is always set at Stage 0, when . Accuracy and Evasion also work in a similar means, just with different multipliers; Accuracy being a multiplication of the user's attack accuracy and Evasion being a multiplication of the attacker's attack accuracy. Some items and abilities also increase the Pokémon's stats, these are unrelated to the Stat Modification here and work in addition to these and not as part of them

There are however, a variety of attacks and abilities that negate & prevent these stat changes. They are as follows:

Attacks:
