Slowpoke has two possible evolutions: Slowbro or Slowking. They are alternative branches, not two stages that happen one after the other, so any individual Slowpoke evolves once into one of them. The same branching idea applies to Galarian Slowpoke, which can become Galarian Slowbro or Galarian Slowking.
The exact method depends on the Pokémon game and, for the Galarian form, the regional items available in that game. In the standard evolution data, Slowpoke becomes Slowbro at level 37, while Slowking requires a trade with a King’s Rock. Galarian Slowpoke uses different items in Pokémon Sword and Pokémon Shield. Those details are game-specific, so the safest answer is “two possible outcomes,” not “two evolutions.”

How many times does Slowpoke evolve?
Slowpoke evolves once per Pokémon: it branches into either Slowbro or Slowking. The Pokédex evolution diagram presents these as two choices from Slowpoke rather than a sequence in which Slowpoke becomes Slowbro and then Slowking. The official Slowbro Pokédex entry shows the standard branch alongside Slowking.
That means the number can be described in two ways:

- Number of possible evolution outcomes: two.
- Number of times one Slowpoke evolves: one.
Galarian Slowpoke has the same two-branch structure, but its outcomes are the regional forms Galarian Slowbro and Galarian Slowking.
What are Slowpoke’s two standard evolutions?
| Starting Pokémon | Possible result | Method in the reviewed standard evolution data | What the choice means |
|---|---|---|---|
| Slowpoke | Slowbro | Reach level 37 | Slowpoke follows the level-based branch. |
| Slowpoke | Slowking | Trade it while it holds a King’s Rock | The trade-based branch is selected instead of the level-based one. |
| Galarian Slowpoke | Galarian Slowbro | Use the Galar-specific evolution item described for the Isle of Armor | Produces the regional Slowbro form. |
| Galarian Slowpoke | Galarian Slowking | Use the Galar-specific evolution item described for the Crown Tundra | Produces the regional Slowking form. |
The first two rows summarize the methods listed by Bulbapedia’s Slowpoke evolution data. Because Pokémon games change how encounters, items and trades work, treat the methods as a standard reference rather than a universal instruction for every title.

For the standard form, the level-based route leads to Slowbro at level 37. Once the game recognizes that Slowpoke has reached that level, the normal evolution prompt can produce Slowbro. This is the straightforward branch for players who want Slowbro without arranging a trade or obtaining a held evolution item.
Level 37 is the key threshold cited in the reviewed evolution reference, but the practical experience can differ by game. Some games may handle evolution prompts, cancelled evolutions or level gains in slightly different ways. If the evolution does not happen when expected, check that the Pokémon actually reached the required level and that an evolution was not cancelled; then consult the rules for that specific game.

Choosing this route does not create a second stage later. Slowbro is the endpoint of that branch for that Pokémon. A Slowpoke that has already evolved into Slowbro cannot be changed into Slowking by levelling it again.
How does standard Slowpoke evolve into Slowking?
Slowking is the alternate standard branch. The reviewed reference describes it as a trade evolution: Slowpoke must be traded while holding a King’s Rock. The trade and held item together are the relevant conditions; simply levelling Slowpoke will not select this branch.

You need a compatible trade connection and a second game, console or trading partner as supported by the title you are playing. If the evolution does not trigger, verify that the item is the King’s Rock, that Slowpoke is holding it at the moment of the trade, and that the game supports this evolution method. Do not assume that a modern title uses exactly the same trade rules as an older one.
As with Slowbro, Slowking is the end of the branch for that individual Pokémon. The phrase “Slowpoke evolves twice” is therefore misleading: the trade does not happen after a Slowbro stage, and Slowking is not a later upgrade to Slowbro.

What happens with Galarian Slowpoke?
Galarian Slowpoke also has two alternatives, but the results are regional forms: Galarian Slowbro or Galarian Slowking. The official Pokémon Sword and Pokémon Shield page explains that Galarian Slowpoke can evolve into Galarian Slowbro with an item found on The Isle of Armor, or into Galarian Slowking with an item found in The Crown Tundra.
The reviewed evolution reference names those items as the Galarica Cuff for Galarian Slowbro and the Galarica Wreath for Galarian Slowking. These are not interchangeable names for the standard King’s Rock method. They belong to the Galarian evolution system associated with the Sword and Shield expansion areas.
Recommended Free Tools
Availability matters here. The Isle of Armor and The Crown Tundra are Sword and Shield expansion content, so this description should not be read as an instruction that applies automatically to every Pokémon game containing Slowpoke. A game may include Galarian Slowpoke without using exactly the same item access, downloadable content or evolution interface.
Is Slowpoke’s evolution available in every Pokémon game?
No. The two-branch design is the core species information, but individual games can restrict which branch exists or how it is obtained. The reviewed reference specifically notes that Slowking is unavailable as an evolution outcome in Pokémon: Let’s Go, Pikachu! and Pokémon: Let’s Go, Eevee!. It also records a National Pokédex restriction affecting Slowking in Pokémon FireRed and Pokémon LeafGreen.

These exceptions explain why a method copied from one game can fail in another. Before collecting a King’s Rock or setting up a trade, identify the exact title, version and available Pokédex. For Galarian Slowpoke, also check whether the relevant Sword and Shield expansion content is accessible. The species can have two theoretical branches while a particular game exposes only one of them, or neither in the same way.
Which Slowpoke evolution should you choose?
The choice is mostly a matter of the form you want and the method your game permits. Choose the Slowbro branch if you want the level-based route and do not want to trade. Choose Slowking if your game supports the trade method and you specifically want that evolution. For Galarian Slowpoke in Sword and Shield, choose the Galarica Cuff route for Galarian Slowbro or the Galarica Wreath route for Galarian Slowking.
A useful decision process is:
- Identify the form. Confirm whether your Pokémon is standard Slowpoke or Galarian Slowpoke. The regional form has different outcomes and item requirements.
- Confirm the game. Check the title and version before following a guide. The Let’s Go games and the FireRed/LeafGreen Pokédex rules are documented exceptions.
- Pick the outcome. Decide between Slowbro and Slowking, or between their Galarian counterparts, before using an item or initiating a trade.
- Check the method. Standard Slowbro uses the level-based route; standard Slowking uses the King’s Rock trade route. Galarian outcomes use their named regional items where supported.
- Keep a backup if needed. If you want both outcomes for a collection, plan to raise or obtain another Slowpoke rather than expecting one Pokémon to take both branches.
Why do some guides say “two evolutions”?
“Two evolutions” can mean either two possible results or two separate evolution events. For Slowpoke, only the first meaning is correct. The Pokédex presents a branching family: one starting Pokémon, two possible next forms.
This distinction is useful when reading guides, trading listings or Pokédex completion notes. A guide that says “Slowpoke has two evolutions” is normally counting Slowbro and Slowking. It is not claiming that your Slowpoke must evolve once and then evolve again. The same wording applies to the Galarian family, where the two results are Galarian Slowbro and Galarian Slowking.

Can you see both branches in one Pokédex?
In a game that supports both outcomes, the evolution family may show Slowbro and Slowking as separate branches from Slowpoke. That visual layout is the reason the answer is often summarized as “two,” even though each individual Pokémon proceeds through only one branch.
Regional forms can be displayed separately or grouped differently depending on the game’s Pokédex interface. Use the species form and the game’s own evolution screen as the final authority when the display differs from a general reference.
Quick checklist before evolving Slowpoke
- Write down the exact game and version.
- Check whether your Pokémon is standard or Galarian Slowpoke.
- Choose the desired result before starting the evolution.
- For standard Slowbro, verify the level-based requirement in that game.
- For standard Slowking, verify the King’s Rock trade method and trading support.
- For Galarian Slowbro or Slowking in Sword and Shield, confirm access to the relevant expansion area and regional item.
- Review game-specific restrictions, especially the Let’s Go titles and the FireRed/LeafGreen National Pokédex note.
How we determined the answer
The count comes from the official evolution diagram and species pages, while the method details and game exceptions come from the reviewed evolution reference. The official Sword and Shield material establishes the two Galarian outcomes and ties their items to The Isle of Armor and The Crown Tundra. Because availability rules vary by title, the article separates the species-level answer from game-by-game instructions.
Frequently Asked Questions
Can one Slowpoke become both Slowbro and Slowking?
No. One Slowpoke reaches one branch and remains that evolved Pokémon. To register both outcomes, you need another Slowpoke or another permitted way to obtain the missing evolution in the game you are playing.
Do standard Slowpoke and Galarian Slowpoke use the same evolution item?
No. Standard Slowking uses the King’s Rock trade method in the reviewed data. Galarian Slowpoke’s Sword and Shield routes use the Galarica Cuff or Galarica Wreath instead.
Why can’t I evolve Slowpoke into Slowking in Pokémon Let’s Go?
The reviewed evolution reference lists Slowking as unavailable as an evolution outcome in Pokémon: Let’s Go, Pikachu! and Pokémon: Let’s Go, Eevee!. That is a game restriction, not evidence that your trade setup is missing a step.

Where are the Galarian Slowpoke evolution items found?
The official Sword and Shield information associates the Galarian Slowbro item with The Isle of Armor and the Galarian Slowking item with The Crown Tundra. The named items are the Galarica Cuff and Galarica Wreath, respectively.
