For me to clarify on m earlier post; I was referring to light as sunlight. Without sunlight, you can't have grass, water, etc. Therefore, a Light element would more alligned as "Creation"
And Void is destruction, the absence of life, so a Void element would be alligned with "Destruction"
I say this, because we have the Dark type, but it's considered Dark from it's cheap way of fighting (see sucker punch, payback, taunt, pursuit, bite, and crunch if you don't get it. They're cheap ways to fight) which is why the fighting type, or the noble way to fight, is super effective, and why psychics can't control them, because of their nasty minds and such. It's why the Dark type is called the Evil type in Japanese
(forgive me, most of you know this, Im just restating it to backup my idea)
So if you look at it that way, the Dark type can't really work against the Light type if that were to happen, so to add a Void type would be a god parallel.
