Did Slug tried to hide he is a Namekian?

Since i watched DBZ Movie 4, i wondered, did Slug tried to hide the fact he is a Namekian? He wore this helmet and outfit, that hid his appearance, if he did, i wonder, what was the point? Was it only because to keep audience in suspense, from what race main villain is? Even in title Toei hide it (as well as in rest of world, only French people spoil it, by giving movie title "La Menace De Namek")

I think it was pretty clear, even with the helmet.

I believe that it was mostly for the suspense part (even though I believe that with hat skin color, those eyes and those teeth, it was pretty clear that he was a Namek). And also, in-universe, for the reactions of the main characters.

Well, I suppose it was for everyone but the viewers. The only green aliens WE saw are namekians, but in a world like the DBZ one, I bet a ton of green people existed.
