Pokémon without a release date: Here are more highlights of the season, but it is still not entirely clear when they will appear. However, they will exchange between September and December – the current season timeframe.
Mega-Metagross and Mega-Camerupt

Both Mega Pokémon are scheduled to debut in the current season, but a specific date is still not known. While Camerupt is likely to be more of a Dex entry, Mega-Metagross is one of the best Pokémon in the game and should become a powerful attacker.
Sirapfel and Hydrapfel
The apple Pokémon Knapfel is already in the game, and now further developments of the monster are added: Sirapfel and Hydrapfel. When exactly is still unknown, but definitely during the season. You can read more about the Knapfel developments here.
Gigadynamax-Deponitox
Unratütox and Deponitox, the living versions of a trash bag, have been in the game for a long time. Now their gigantic trash mountain form Gigadynamax-Deponitox is being added. Collecting the Gigantamax forms is always a challenging but exciting task. When exactly it will appear is still unclear.
Mega-Rayquaza

One of the absolutely most powerful Pokémon in the game. Mega-Rayquaza appeared briefly in the graphics for the new season and in the trailer. When exactly it will appear is unclear. However, it is clear that you should get this monster if you don’t have it yet.
Dynamax-Duraludon
Duraludon is a Steel-type Pokémon from the Galar region that is not yet catchable in the game. However, its Dynamax form is now announced for the current season (exact timing still unclear). Here you can look forward to a new Pokédex entry.
