Something that went through my mind tonight.

Would the plural of "po'qeymon" be "po'qeymonmey" or "po'qeymonpu'"?

I could see a -pu' plural because Pokémon each speak in their own language. It's not a language shared with any sapients, but Pokémon do speak languages.

However, all Pokémon can say is their own names. And as far as I know, no human has ever spoken to a Pokémon in its language. So maybe the plural takes -mey.

What are your thoughts?
