Pokemon Uncanny Version ROM

Pokemon Uncanny Version is a GBA ROM Hack by RetroNC based on Pokemon Fire Red. It was last updated on April 05, 2025.

Description

In Pokemon Uncanny, you can catch some non-Pokémon, such as anime-exclusive forms, Manga nightmare fuel, humans because they technically show up in a Pokemon battle, Charizard Two, a mongoose, Crystal Onix, and much more. It features 75 new non-Pokémon with full evolution chains. 

Features

• The only findable Pokemon in the game are the 75 new “Non-Pokémon additions.”
• Every “Non-Pokemon” has everything new(sprites, icons, stats, etc), except cries.
• The map and story are mostly unchanged, instead having boss battles and a new champion (with non-pokemon teams).
• Uses the “Complete Fire Red Upgrade” – means that the ROM has a good amount of modern mechanics, moves, etc.
• The Non-Pokemon do not have new Pokedex entries. (The best you can do is Google each of their origins.)
• Each design has a shiny version as well. Shiny odds are not changed.
• If there’s a regular Pokemon in the game, it means that the last evolution is new. (vice versa for first stage being new, last being regular)
• Every Non-Pokemon has their origin listed in its dex entry.

Known Bugs

• Game Corner may cause the game to crash if you end up getting a jackpot.
• The reason is unknown, but your Non-Pokemon may suddenly get the “boosted exp” trait that traded Pokemon usually only have.
• I don’t recommend using PkHex. If you use PkHex, any changes may cause edited/added Non-Pokemon to have unexpected issues or messy data.
• Registered Bicycle may be randomly replaced with an item upon selection.
