Pokémon Go's Meltan, the new Nut Pokémon, is somewhat unprecedented for the series - a debut of a new, never-before-seen creature outside of the main games or anime.

We now know a bit more about how to catch Meltan, with official details trickling out on a new item, the Mystery Box, details of how to get Meltan in Pokémon Let's Go, and some related winter Special Research for Pokémon Go, too.

The new mystery Pokémon - and it's strange 'nut' and Ditto-like appearance - made its debut after the conclusion of the September Community Day, but after some datamining and suspicions that it might be related to the introduction of Kecleon, we now finally have some official information.

Meltan and the Mystery Box explained - how to catch Meltan and how the Mystery Box works in Pokémon Go

Catching Meltan seems to work a little differently to its Mythical counterparts Mew and Celebi in Pokémon Go - and indeed their traditional catch methods in mainline Pokémon games.

For the first time ever, you're going to need to catch a Pokémon in a non-mainline game first before you can catch it in a mainline game. In fact, it seems you're going to need both the mainline Pokémon Let's Go game (either Pikachu or Eevee version) on the Nintendo Switch, as well as Pokémon Go to get it in either.

It's not possible to catch Meltan just yet, but we do know the basics of how it'll work.

Mystery Boxes and how to catch Meltan

  1. First, you'll need to transfer a Pokémon - presumably any Gen 1 Pokémon - from Pokémon Go to a copy of Pokémon Let's Go. This can be either your own or a friend's copy of Let's Go. It's not clear if you'll need to be in-game Friends officially for it to work however, but presumably you will.
  2. Doing so will award you a Mystery Box back in Pokémon Go, which can be opened for just 30 minutes, letting multiple wild Meltan out into the wild in your Pokémon Go game, where you can catch it.
  3. After 30 minutes the Mystery Box will close, and wild Meltan will stop appearing in Pokémon Go for you. It will stay closed for an undisclosed period of time.
  4. Once that 'cooldown' time has elapsed, you can open the Mystery Box again to let more Meltan out into the wild in Pokémon Go - to do so, you need to transfer another Pokémon from Pokémon Go to yours or a friends copy of Pokémon Let's Go.

Importantly, it's also worth noting that there will be additional, new Special Research tasks coming "this winter" to Pokémon Go, which will allow players "to assist Professor Willow's ongoing investigation into Meltan". It's not clear yet whether you'll need to complete them in order to open the Mystery Box, or if you can even use that Special Research to catch Meltan without a copy of Let's Go altogether, so we'll update this page when we know more!

How to catch Meltan in Pokémon Let's Go Pikachu and Eevee

To get Meltan in Pokémon Let's Go, on the Nintendo Switch, you'll need to follow the above steps, getting Meltan in Pokémon Go first, and then transfer Meltan from your copy of Pokémon Go to your copy of Pokémon Let's Go.

That's done via the usual method, which is by transferring it to a place called Go Park in Let's Go. Again, like other transferred Pokémon, you then need to enter Go Park and catch it in Pokémon Let's Go, and then it's properly yours.

It seems like you can catch and transfer multiple Meltan into Pokémon Let's Go Pikachu or Eevee, and presumably whatever that other Pokémon, form, or evolution was that was teased via the second trailer will also be available in Let's Go somehow, too - although no news there just yet!

What is Meltan, the new Pokémon in Pokémon Go, and does it have a new form?

Meltan is a completely new Pokémon, originally introduced through a kind of viral marketing event where players first thought they'd stumbled across some kind of error from Pokémon Go developer Niantic.

It looks suspiciously like a Ditto - albeit in a different colour and with a big ol' metal nut on its head - but as you'll see in the announcement video just below, it's actually an entirely new, Mythical Pokémon, putting it in the same sort of bracket as Mew and Celebi in terms of rarity and intrigue.

In terms of other information about what exactly Meltan is, we got a few more details teased through by the Pokémon company:

  • It's a Steel-type - Which makes sense, given the name and the whole nut thing it's got going on, although it's worth noting that its body isn't plain grey, it's a kind of metallic silver, as well.
  • It's ancient, as well as mythical - Professor Oak mentioned this in the video, and we were treated to an unusual, carving-like image of Meltan, presumably from ancient times.
  • It sounds like it could be pretty powerful - Meltan can absorb energy from around it and fire it from its eye (yes, that's an eye), apparently!
  • It has an official description - Every Pokémon has one: Meltan is the "hex nut Pokémon". Intriguing use of the word "hex" there.
  • It seems to be linked to Ditto - Obviously there's the visual link, with Meltan's body looking a lot like Ditto's, but also the fact that Meltans caught in Pokémon Go have all transformed back into Ditto so far. Interestingly, although it originally seemed to be hinted at in the trailer above, Ditto are confirmed to be unable to transorm back into Meltan once caught.
Meltan_Evolution_tease
Evolution, or new form?
  • It's the new Pokémon announced for Pokémon Let's Go - The new Pokémon games on the Switch were known to be getting a single new Pokémon, so it looks like Meltan is it - but could it actually be multiple Pokémon in a new evolution chain?
  • There are multiple Meltan to catch - That's right, despite Meltan being a Mythical Pokémon (up until now known for being the 'only' ones of their kind, so you can usually only catch one), it seems that multiple Meltan can appear and presumably be caught.
  • Meltan seems to have a bigger final form - Teased at the end of the second Meltan video was a silhoutte, which seemingly showed Meltan's golden Nut of a head on a much larger, more imposing body. In fact, it looked quite similar to the final form of Zygarde, which was also first introduced as a number of smaller versions (in Zygarde's case they were 'cells') that made up a larger, competitively stronger whole. It seems like Meltan could be similar? It's not clear whether it's a new form or an entirely new, related Pokémon like another evolution, however.

Here's a new video teasing a little more about Meltan, the Hex Nut Pokémon, including that apparent final form:

How we first encountered Meltan, Pokémon Go and Let's Go's new Nut Pokémon

The mysterious Meltan appeared in the wild in Pokémon Go at the conclusion of the September Community Day, flooding the map en mass.

Though it seemed like a regular creature - complete with its own animations, and even appearing on the Nearby radar - there were a few key differences:

  • It had no name or CP
  • Catching it would see it transform into Ditto
  • As a result, after catching, there is no record of it in your Pokédex or elsewhere

30 minutes after appearing at the end of Community Day, the spawns then slowed right back down to rare or uncommon levels - similar to a regular Ditto's spawn rate, and then disappeared entirely.

It appeared, at first, as though some of these Meltan-Ditto could transform back into Meltan, but then Pokémon issued a clarification:

What else do we know about Meltan, the Hex Nut Pokémon?

Aside from what we know about it as a Pokémon itself, there are a few other things to note about Meltan in general.

Meltan_in_Pokemon_Let_s_Go
  • According to the official press release concerning Meltan, "It looks like Meltan is very curious and loves metal objects."
  • Meltan is likely the only new Pokémon coming to Pokémon Let's Go Pikachu and Eevee on Switch - unless that teased silhouette is actually an evolution or another related Pokémon.
  • Due to the way it's numbered in the game files, Meltan is arguably a 7th generation Pokémon, rather than an 8th, and according to this thread on the Silph Road subreddit, the way it's numbered also indicates that its full Pokédex number won't be 891. It's most likely that this is Pokémon number 808, following on from Ultra Sun and Ultra Moon's final new Pokémon, Zeraora.

Exciting times then, really! This is something we've never seen before in Pokémon Go, so it's been a real mystery. As we're in uncharted territory in terms of Pokémon announcements and introductions to the mainline games, the next steps are unknown, but we'd like to think some clues appear again sometime very soon - with hopefully a few steps to get started on bringing it to Let's Go!
