Unused icons and file data point to a large wave of returning Pokémon for late-2026 DLC and preceding events.
A major datamine of Pokémon Pokopia game files, enabled by the recent availability of Nintendo Switch 2 ROM dumping tools, has revealed a substantial set of unused Pokémon icons and supporting data. Community researchers interpret these as strong indicators of content planned for Expansion Pass Part 2 (targeted for late 2026) along with limited-time events that may arrive beforehand.
The most consistent lists drawn from the in-game icon sheet and related assets include the following Pokémon that are not currently available in the base game or the Bubbly Basin (Part 1) DLC:
Supposed Leaked Roster for Expansion Pass DLC 2:
- #0010 | Caterpie
- #0011 | Metapod
- #0012 | Butterfree
- #0084 | Doduo
- #0085 | Dodrio
- #0209 | Snubbull
- #0210 | Granbull
- #0225 | Delibird
- #0300 | Skitty
- #0301 | Delcatty
- #0387 | Turtwig
- #0388 | Grotle
- #0389 | Torterra
- #0488 | Cresselia
- #0548 | Petilil
- #0549 | Lilligant
- #0653 | Fennekin
- #0654 | Braixen
- #0655 | Delphox
- #0684 | Swirlix
- #0685 | Slurpuff
- #0868 | Milcery
- #0869 | Alcremie
Also frequently grouped with a possible pre-DLC event:
- #0840 | Applin
- #0841 | Flapple
- #0842 | Appletun
- #1011 | Dipplin
- #1019 | Hydrapple
Some reports additionally suggest Delibird and Cresselia could tie into later holiday or New Year windows, and that Part 2 may introduce an Alcremie “character” role in the same vein as existing special Pokémon characters such as Tinkmaster or Smearguru.
These findings line up with earlier official teases that Part 2 would add further Pokémon (including previously shown names such as Snubbull, Skitty and Braixen) plus wearable accessories. Part 3 remains scheduled for 2027 and is expected to bring a new town.
Beyond the roster, broader file reconstruction work (notably by Pokéos) has extracted extensive internal data already present in the current game: all 257 habitats with images, building requirements and spawn conditions; more than 1,500 items with icons, recipes and values; full preference data for every Pokémon; expanded Human Records documents (including newly accessible Bubbly Basin material and previously incomplete story pages); and a complete icon/asset archive.
Editor’s Note: Everything above originates from community datamines of dumped files. Nintendo and The Pokémon Company have not confirmed the roster, event timing or exact implementation. Icon presence has historically been a reliable signal in Pokémon titles, but it remains unconfirmed until an official reveal. Treat the lists as provisional.
