>>59035404https://serebii.net/pokemonchampions/pokemon.shtmlWhat seems to be included at launch:
- Every non-legendary Pokemon with a Mega (Mega Floette is also confirmed, idk if that's a mythical or not)
- Possibly every starter line (Basing this entirely on the inclusion of Serperior and Empoleon)
- Every Eeveelution
- Every Hisuian Form of a pre-existing Pokemon
- Every new evolution from the DLC of Scarlet & Violet
- Every pseudo (I think the only one not present on Serebii's list is Baxcalibur, who should be included by virtue of having a Mega)
- A wide selection of popular VGC mons (Whimsicott, Talonflame, Tsareena, Oranguru, Hatterene, Tinkaton, Dondozo, Tatsugiri)
The remaining known Pokemon all tend to be very good, either great in single battles and/or still worthy of consideration for VGC teams. Milotic is maybe the only random Pokemon there who wouldn't be considered that formidable in competitive play. Pikachu is there, but that doesn't necessarily mean there's many NFE Pokemon available. Magikarp and Emolga have only appeared in the opening cutscene outside of battles, and I feel that does not necessarily mean they are available.
