Blastoise is one of the most iconic Water-type Pokemon in the series, and in Pokemon Legends: Z-A it keeps that classic power and tanky style we all expect.
In the Lumiose Pokedex, Blastoise is listed as #156, standing 5'03" and weighing 188.5 lbs.
Blastoise's Pokedex note says it can crush enemies with its heavy shell and hide inside it when things get rough — which honestly fits its tank role perfectly.

Blastoise cannot be found in the wild in Z-A. The only way to obtain one is through evolution.
Here's the full line:
So the real “how to get” step is simply leveling your Wartortle. I recommend using EXP Candies or focusing on multi-Pokemon battles if you want quick progress. Z-A leveling is pretty smooth, so you'll hit 36 faster than you think.
Q: Does Blastoise spawn anywhere on the map?
A: Nope. Zero overworld locations. No den spawns, no rare weather spawns — nothing.
If you want Blastoise, your path is locked to evolving your Wartortle or trading with another player.
Blastoise sits at 530 total combat points, which puts it in that good-but-not-glass-cannon range. It's a defensive Pokemon first, and its numbers reflect that.
If you like bulky Pokemon that can stay on the field, Blastoise is super reliable. It doesn't hit as hard as some offensive Water-types, but it shines in longer fights. I personally like running it with moves that take advantage of its high defenses — it's one of those Pokemon that feels better the longer you use it.
Since Blastoise can't be caught in the wild, you can only get a shiny Blastoise by evolving a shiny Squirtle or shiny Wartortle.
Here are your realistic methods:
Shiny odds aren't terrible in Z-A, but Squirtle outbreaks can be competitive, so patience is key.
Because Blastoise does not spawn in the wild, Alpha Blastoise also cannot spawn naturally.
The only ways to get an Alpha version are:
So if you're hunting Alpha forms, focus on Squirtle outbreaks or areas where its pre-evolutions appear.
Direct “buying” in-game isn't possible, but you can trade for one. Many players swap extra Wartortles or Blastoises pretty cheaply.
And as mentioned, if you're specifically looking for shiny Blastoise, you can also buy one safely through U4GM.
Blastoise in Pokemon Legends: Z-A is an evolution-only Water-type that shines as a tank. You can't find it in the wild, and shiny or Alpha versions can only come from evolving special Squirtles/Wartortles or trading. If you want the shiny without grinding, U4GM is viewed as the best place to buy shiny Pokemon.
