Dark Keyblades...

Nice theory. It's true that there could be a dark keyblade for every keyblade, just as there's darkness in every heart.
Man, we should be Kingdom Hearts philosophers.

 

Yeah, that theory was pretty awesome though.

 

Yeah. I bet that's actually gonna be in KH3D or KHIII

 

hmmm maybe....But it's still only speculation nothing more. I need more solid evidence to buy it.

 

but the Kengdom Key D was described as the Dark Realm's keyblade not the kingdom key's dark side. so it's not really a valid argument.

 

nooo he found it in the realm of Darkness. the realm where Heartless come from. and the way Yen Sid said it it sounded like Kingdom Key D was the only keyblade to be found there.

 

Some keyblades must be left not for darkness. Anyway, this is a great idea, but not all keyblades must have not an alternate version. I suggest you to find more story about of this? You can create one.
This could be in a upcoming game by the way, hope so..

 

well hold on, trio dont kill legacy just yet. I shot down your theory too, but you never threatened to kill me.

 

You do both have good points.
To Knight: I think he got angry at Legacy because Legacy has a tendency to swoop in and shoot down theories with logic. No offense, haha.

There, of course, would be keyblades without dark counterparts. But Trio's theory is pretty awesome.

 

awesome or not, it still needs solid evidence.

 

It's more of a ''Well if this logic was applied here...'' kind of theory.
Like, if there's darkness in every heart, for example, then there's darkness in the heart of every world. So there would be an anti-form of every world. Or not. That's not the point.
The point is that actually, there are no different types of keyblade, persay. Different keychains change the keyblade. So if the Kingdom Key, the base of all keyblades, has an anti-form, then surely every keyblade would?
I wouldn't call it solid evidence, but it supports the theory at least.
