is it true that you can get new keyblades in birth by sleep . THAT'd BE AWESOME!

well i think you'll be able to.. since you got new keyblades in KH 358/2 Days~

URRHMM. the how come in like every game play . the characters use the same keyblade. dont get me wrong they're awesome keyblades buuutt i'd like to get a variety of keyblades!

Considering in every other kindgom hearts game (with the exception of CoM, even though you had various keyblade cards, you only ever used the kingdom key) there were a variety of keychains available for use.

So it can be assumed that there will be multiple keyblades.

 

And normally for demos ad such, they use the standard keyblade while playing.

YAY !

of course or that would ruin the game O_o jk lol

You don't have mutiple keyblades. You have mutiple Keychains in Kh1 through KH2(all games inside except CoM)

 

But this system has been substituted for the Growth system. As we have seen the changing of keyblade. Which leads us to the growth system, keychains have appeared and we have a different look of the exact same keyblade.(with little changes)
