I know this one is no regional forms so this question may not have an easy answer: you have Darmanitan normal and zen, but it's Galar form also has a 'normal' and zen so should it may be included as a second entry as a Regional that also has forms? It was actually Paldean Tauros that made me think about this. Maybe more of a philosophical question 🤔
That's something I didn't think about. I decided to put Paldean Tauros as grayed out as kind of a middle ground. Darmanitan is a bit trickier, because putting it grayed out would give away that it is an answer. I think it's fine to not show Galarian Darmanitan because its two forms are the same as regular Darmanitan's two forms.
Eevee has Partner Eevee from the Let's Go games, and this would also increase Pikachu's forms by one.
Technically Own Tempo Rockruff is a form, but that's dumb and I don't think it should be included.
Koraidon, Miraidon, and Pecharunt all have other named forms, the various bike upgrades and dormant, I would personally include them but I understand deciding not to.
