Evolutions and Strength

[MasterBa11er]

Anyone know if evolution affects stats? Sorry for the noob question. Example would a level 40 Sandshrew with same IVs as level 40 Sanslash be weaker than the Sandslash?

 

[Nah]

Each Pokemon species has its own base stats, so when a Pokemon evolves, its base stats change to whatever it has evolved into. There are other things that determine what exactly a Pokemon's stats are at any given point (level, EVs, the IVs you mentioned, natures, etc), but in most cases this does result in the Pokemon now having higher stats than it did before evolving, as the evolved form usually has higher base stats. In the Sandshrew/Sandslash example, the Sandslash will almost certainly be stronger.

Yes. Bumps up the stats to the new form. Example stats with a level 40 Sandshrew and level 40 Sandslash, both with maximum IVs and no EVs:

• Sandshrew: 102 Hitpoints, 77 Attack, 85 Defense, 33 Special Attack, 41 Special Defense, and 49 Speed.
• Sandslash: 122 Hitpoints, 97 Attack, 105 Defense, 53 Special Attack, 61 Special Defense, and 69 Speed.

Added 20 to each stat in this case. Will not always be so even for other Pokemon, however.

A slightly more in-depth answer: Assigns something called "base stats" to every Pokemon. Determines what their stats will be. Cannot see base stat numbers in-game.

• Sandshrew's base stats: 50 Hitpoints, 75 Attack, 85 Defense, 20 Special Attack, 30 Special Defense, 40 Speed
• Sandslash's base stats: 75 Hitpoints, 100 Attack, 110 Defense, 45 Special Attack, 55 Special Defense, 65 Speed

Calculates hitpoints with this formula:
HP = floor(((2 * basestat + IV + floor(EV / 4)) * Level / 100) + Level + 10

So, for a level 40 Sandshrew with 31 IVs, 0 EVs, and a base HP stat of 50:

HP = floor(((2 * 50 + 31 + floor(0 / 4)) * 40 / 100) + 40 + 10
HP = floor(((100 + 31 + 0) * 40 / 100) + 50
HP = floor(131 * 40 / 100) + 50
HP = floor(52.4) + 50
HP = 52 + 50
HP = 102

Got 102 hitpoints, which is the number of hitpoints mentioned above.

Uses a different formula for other stats:
floor(floor((2 * basestat + IV + floor(EV / 4)) * Level / 100) + 5) * Nature

Try not to get lost in all the parentheses. Sticks in 1.1 for a helpful nature, 0.9 for a hindering nature, and 1 for any other.

Wow, thank you for such a detailed response. That's great to know!

Normally, when a Pokémon evolves all of its stats raise (how much they increase depends on the species. E.g. Pupitar will receive a 190 total base stats increase when it becomes Tyranitar, while Misdreavus will only get a total +60 BST. Each species scale in strength at their own pace, so don't underestimate weaker Pokémon as they might sometimes end up becoming way stronger)

There are a few exceptions to this though. Sometimes not all stats increase, certain Pokémon will actually lose points in some stats although their overall strength will be still superior. For example Poliwag becomes slower each time it evolves.
