Elite Redux features many new Pokémon that are classified in different ways; Redux Forms, Convergents, new mega evolutions, new evolutions, and new Paradox Pokémon. For more details of each Pokémon, use the Online ER Dex.
Redux Forms
Redux Forms are variants of Pokémon that have adapted to a new environment, similar to Alolan, Galarian, and Paldean Forms. The origin of redux forms is still under investigation. Most Redux Forms can be obtained from the Adoption Center, with the exceptions of Redux Noibat, which can be found in Seaspray Cave, and a few others which a currently unobtainable.
The first redux form was added in the 1.6 update. 2.2, famously known as the Redux update by some people, was the update that had added most of the Redux forms we have on version 2.5. A lot of these Redux forms can be found in the Adoption Center. The latest 2.5 update added many new Redux forms alongside new evolutions.
Convergent Pokémon
Convergent Pokémon are similar to regional forms, but they are treated as entirely new Pokémon, akin to Pokémon such as Toedscool and Tentacool. Elite Redux introduces 3 new Convergent Pokémon lines, which can be bought from the Adoption Center after a certain amount of badges. More Convergent forms are to be added in later updates.
*Bubbleo and Hydroar are listed on the 2.5 dex site, but are currently unavailable.
New Evolutions
Many Pokémon are given new evolutions, whether it be an extension to the line, such as Magcargo to Escarginite, or a new split evolution, such as Magikarp to Gyaradeath. Since all Pokémon evolve by level now, the level at which these evolutions are obtainable are given in the final column.
New Pre-Evolutions
As of currently, Elite Redux introduces 1 new pre-evolution, Knaiver, a prevolution for Scyther, Scizor, and Kleavor. As such, since Scyther has the same BST (Base Stat Total) as Scizor and Kleavor, Scyther no longer evolves to these Pokémon.
Mega Evolutions and Primals
Elite Redux adds many new Mega Evolutions and Primal Forms, as well as turning Gigantamax Forms into Mega Evolutions.
Paradox Pokémon
Paradox Pokémon originated from the mainline Pokémon games, Scarlet and Violet, which had Past and Future Paradox Pokémon respectively. Elite Redux expands on these Pokémon by creating new Paradox Pokémon for existing Pokémon.
Future Paradox Pokémon
Past Paradox Pokémon
Other Pokémon
These are miscellaneous Pokémon that have no other public classification. As of currently, none of these are unobtainable through normal means.
Monochamp Pokémon
Monochamp Pokémon are special Pokémon that are created to reward users from the Discord who were the first to receive their respective typing's monochamp title. These forms can vary in their classifications. None of these are currently obtainable.
