please dont make a big deal about this, but a while back i found a post about what keyblades are in kh2 and if you are able to make one yourself.

this link shows the article that confirmed that "make-it-yourself" idea.

its kinda a cool idea, makin' your own keyblade.

You don't actually get to create it, it's like synthesis from the first game.

Well I dont know exactly, but on that article it sais (similar to synthesis)

 

[Strongbad02]

Yah, but we can only hope.

Hopefully, you might be able to actually use custom designs for different Keyblades, like a MegaMan.EXE type. Or even a WarpStar Keychain.

Hey i think is kinda because in KH1 u know guys u can create or better say customize a gummi ship, why u cannot custimize a keyblade from u own...

Three Trinity Hmmmm Sound Good

My guess is you can kind of make custom keyblades by choosing from different designs and changing the stats. Maybe as you find different keychains you unlock more designs?

Im happy as long as I get a keyblade!

 

[Mezmerize]

SWEET!! We get to make our own keychains!? Thats awesome!!

I think you get to MODIFY your keyblade,like make it longer,or a new color.
