Let me know if you need a Nidoking list. I make lists for single Pokémon collectors in all languages and variations pretty often. 
I can’t guarantee it’s 100% correct since I make them in about 45-90 minutes depending on how many releases it has, but it should contain almost all of them. Here that thread and here all the lists I’ve made thus far to give you an idea (more recent ones are more accurate; especially the ones from 2017/2018 contains some errors and are very outdated).
Good luck with your collection goals! Nidoking is an amazing Pokémon (even though it was one of just three Pokémon I never had as a kid of the first 151 Pokémon - the others being Venusaur and Hitmonlee 
).
