What are all of the Pokemon that cannot learn Substitute or Protect (excluding Ditto, Smeargle, Unown)?

Question

The question above. I know that Regigigas didn't get Protect until Gen 8, and now I am wondering what other Pokemon haven't learned Protect/Substitute until now, or just never learned it.

Answer 1

/nds !protect, all:
Applin, Beldum, Blipbug, Cascoon, Caterpie, Combee, Cosmoem, Cosmog, Ditto, Kakuna, Kricketot, Magikarp, Metapod, Scatterbug, Silcoon, Tynamo, Unown, Weedle, Wobbuffet, Wurmple, Wynaut

/nds !substitute, all:
Applin, Beldum, Blipbug, Burmy, Cascoon, Caterpie, Combee, Cosmoem, Cosmog, Ditto, Kakuna, Kricketot, Magikarp, Metapod, Scatterbug, Silcoon, Spewpa, Tynamo, Unown, Weedle, Wobbuffet, Wurmple, Wynaut

Beyond Regigigas gaining Protect in Gen 8, its availability has been the same since its introduction, beyond the addition of new Pokémon of course. For Substitute though, in Generation 2, it wasn't learnable from a Move Tutor or TM, so its list of Pokémon unable to learn it was quite large.

Smeargle isn't included as it can technically learn them via Sketch.
