But why does it matter if they are gender less in Japan?

Let’s google that and find an interview about Kirby by the dev of Kirby in Nintendo or well hal lab

Now if kirby just doesent have a gender, than the japanese Kirby is the ORIGINAL kirby. Not the the localized versions

And you may say "well kirby being a boy is the only official jender other than the japanese version" japanese kirby is stated as unknown, so kirby has a gender but we dont know about it

Dumb ass westerns thought that kirby being a boy would be more "cool"

That is EXACTLY why kirby is mad in the western cover art (i get star allies happy a happy kirby but still)
