What are all the pokémon that we don't know the true appearance?

Question

Mimikyu under its cloth, genesect before team plasma modified it... EVERYTHING. All the pokémon that we don't have idea how they look like.

Cubone, Marowack, kangkaskan (has a baby but when bred it’s just a kangaskan?)
Most ghost Pokemon when they were alive probably,
Tangela and tangrowth, kabuto,
