For the flying egg group page, it says
All Pokémon in this group are part Flying type, except for Decidueye
Since generation 8, that has changed. Now, Galarian Sirfetch'd, Hisuian Decidueye, the Quaxly line, Flittle, and Espathra are all in the flying egg group yet not flying types.
I think this should be updated or just deleted.
Also, Maushold's "Moves Learned" section only has egg moves. It says it does not learn any level-up or TM moves, but other sites, like Bulbapedia say otherwise. It needs to be updated with all of Maushold's actual moves.
Maushold's page should also probably specify that it cannot evolve with EXP candies, it must level up in battle.
The breeding page should be updated. It currently says:
Pokémon are compatible for breeding if:
They are not legendary Pokémon, baby Pokémon, Unown, Nidorina or Nidoqueen
The Galar fossils and Paradox Pokemon are undiscovered, so they cannot be bred. I think it should just be updated to:
Pokémon are compatible for breeding if:
They are not in the undiscovered group (at the right).
Aura Sphere's page says it has 101 accuracy with a larger font instead of infinite accuracy.
Mirror Herb’s page doesn’t mention that if a Pokemon has three moves and is holding it and another Pokemon in your party has an egg move it learns, you can start a picnic so the Mirror Herb Pokemon will learn that move.
Some abilities are not ignored by Mold Breaker, Teravolt, or Terablaze but aren't stated on their pages, which it should to stay consistent with abilities like Aura Break. These abilities are Shadow Shield, Magic Guard, Comatose, Shields Down, or Full Metal Body.
