Its not possible for a pokemon to impregnate a human, right? For context, have this. I run a hot spring and there are alot of volbeat and illumise that fly overhead at night, and since they are classified as ‘human like’ breeding wise, please, please tell me that none of my clients are at risk?

It is indeed impossible for two reasons. First, volbeat and illumise are genetically incompatible with human beings, and thus, they can’t crossbreed (regardless of what early Sinnohan myth may say). Second, one would assume that “please do not engage in intercourse with wild pokémon in the hot spring” would be among your policies because of sanitation issues.
