One Form for All Genders
Unlike words that end in 'o' or 'a', 'neutral' stays the same whether you are talking about a man, a woman, or an object. You say 'el hombre neutral' and 'la mujer neutral'.
Making it Plural
Since this word ends in a consonant (l), you just add '-es' to make it plural: 'los países neutrales'.
Avoiding 'neutralo/neutrala'
Mistake: “La opinión es neutrala.”
Correction: La opinión es neutral. The word doesn't change its ending to match the 'a' in 'opinión'.
