Players have been enjoying The Isle of Armor, but it turns out that the data downloaded to update Pokémon Sword & Shield didn’t just contain information for the recently released DLC. It also included unreleased details about the second half of the Expansion Pass, The Crown Tundra, as well. Today, we’ll be going over what was discovered, which means we need to give you a little warning:
THIS POST CONTAINS SPOILERS! These are not rumors, per se, but the information is about unreleased content which is subject to change before release.
Most of the information we’ll be covering has been uncovered by SciresM and mattyoukhana_, unless otherwise noted. Both are experienced dataminers and have helped uncover many details hidden in game code in the past.

The Crown Tundra region
Many people are curious about how big the Crown Tundra will be. The Isle of Armor contained 17 location zones in the game’s code, and the Crown Tundra also contains the same.
This means we can expect a similarly sized area as what we saw in the Isle of Armor. Considering there is quite a lot to explore there, this is not necessarily disappointing news. There’s no guarantee how large these zones will be, however.
New Pokémon & regional forms in the Crown Tundra
One of these most interesting tidbits hidden in the DLC code was mentions of two brand-new Pokémon that we know nothing about! These are only known by their developmental monikers, “HAKUBA” and “KOKUBA”. Based on the programming, it also appears that they will be able to combine in some way with the legendary of the Crown Tundra, Calyrex. The code names are literally ‘White Horse’ and ‘Black Horse’, respectively. This could tie into the area’s narrative (see title images in the story section below).

This means that there will be two potential forms for it, possibly opening up a choice similar to how players had to choose between Single Strike and Rapid Strike Urshifu in the Isle of Armor.
Other than that, it appears there will be no other new Pokémon, including additional Regis.
Galarian Slowpoke’s other evolution, Galarian Slowking, will also be making its debut in the Crown Tundra DLC.
An alternate form for Zarude, corresponding to the one in Pokémon The Movie: Coco, was also found. This is not necessarily tied to the Crown Tundra and its release, if it gets one, is uncertain.
Returning Pokémon in the Crown Tundra
The exact Pokémon returning in the Crown Tundra DLC is slightly harder to pin down. Bulbapedia researcher abcboy101 has hypothesized that the Pokémon below are what to expect, based on removed Pokédex entries. Take it with a grain of salt.
Notably, this would bring Ultra Beasts to Generation VIII. Sadly no Sewaddle line though…
Story and characters in the Crown Tundra
Some assets for the Crown Tundra’s story were discovered to be in the Isle of Armor data. These included title/chapter/expedition images, including one that hints at the potential for Calyrex to fuse with a new Pokémon (see the explanation above).
It appears that the second DLC will be much more focused on the story than the Isle of Armor was.
Data for characters was also found, including Peony’s daughter by mattyoukhana_. The last character is used for an old man trainer (without glasses) and possibly the village chief (with glasses).
Other details about the Crown Tundra
It looks like 17 new items will be added in the DLC. There will also be events that allow you to capture Regigigas, the Musketeer trio and Keldeo. There’s also a mysterious event that seems to tie in with Vespiquen.

I like that the Ultra Beasts expedition title is like the title of a B-movie.
It perhaps is referencing the movie, “They Came from Beyond Space”
Really hope this reunion happens for me! https://uploads.disquscdn.com/images/61b2a941e597b4159fd415c8500909f4d40c741985b24936a6a32710517586de.gif

I’m gonna be honest, at first I did think it was gonna be that Calyrex fuses with one of the horses because of how their names are coded into the files, but I also remembered the fact that Zacian and Zamazenta both has forms classified as “Crowned” and I feel like we never had an explanation as for why that was the name of those forms. Perhaps instead of fusing with Calyrex, the two horse Pokemon get “Crowned” forms like Zacian and Zamazenta. I could be wrong and could be looking at this completely wrong, but I do think that there might be a connection.
Thing is the special formes are Calyrex formes, not formes of the other 2 pokemon.
I do wonder if they possibly hid more G. forms in the coding cause we know we’re getting G. Slowking in Tundra yet no one has been able to show what it looks like from datamining
And Min-Min joins Smash
Waluigi is dead crab crab
cant wait to see what do those horse look like when they come out
That’s 119 Pokemon, there are still some Pokemon that are not listed that are likely to be expected in the final game, such as…
Deoxys
Craniados
Ramparos
Shieldon
Bastilodon
Darkrai
Shaymin – Dark Void is in SWSH code (Since Victini and Genesect’s signatures are in the game as well)
Arceus – Judgement is in SWSH code (Since Victini and Genesect’s signatures are in the game as well)
Hoopa
That brings to 128
(Already in game but yet have Pokedex Entry)
Mewtwo
Mew
Celebi
Jirachi
The Four Swordsman
Reshiram
Zekrom
Rowlit
Dartrix
Decidueye
Litten
Torracat
Incineroar

Cosmog
Cosmoem
Solgaleo
Lunalla
Necrozma
That’s 152
Since Isle of Armor is 141 and Crown Tundra is possibly 152. Both DLCs are said to have over 200 Pokemon, which is not much but at least trying to calculate.
Or, if we can have our hopes up…

Bayleef
