What is kingdom hearts ?

Is it the door in kh1

or the moon in The World That Never Was

 

and If it was the moon how many kingdom hearts (moon) in kh ? because theres a kingdom hearts in The Keyblade Graveyard and theres a kingdom hearts in The World That Never Was

Kingdom Hearts is the door to darkness seen in Kingdom Hearts 1.

In Kingdom Hearts 2 is the Moon made of hearts that once made completely would turn into the door seen in KH1 and give to the Organization the hearts they wanted... as fo BBS I'm one of the people who don't want to have spoilers so I won't know about it until BBS comes out

kingdom hearts in kh2 was man made and in kh1 it was the door to darkness

I Know Now Deep Down Inside Kingdom Hearts IS LIGHT!!!!

There seems to be only one Kingdom Hearts at a time

I thought it was the heart if all hearts

In Kingdom Hearts, it is the door

In Kingdom Hearts 358/2 Days and Kingdom Hearts 2, it is the moon shaped heart

Kinda right Heartless101.

Kingdom Hearts is Light, and it contains a collection of hearts.

But on the cover art of KH1, there is a moon shaped like a heart, so maybe it can be represented both ways? In BBS, it is shaped as a moon and that must be its true form, although being a door would make sense also so it is the "door and heart of all worlds." I like the heart presentation better.

Sounds like Disney and Square Enix couldn't decide on which it was to be.

Remember when Xemnas was talking to Kingdom Hearts inkh2 then vanished, so did the hesrt moon. After that a big door popped up. Sora and co. said was the door to kingdom hearts, where Xemnas was. So maybe the door in kh1 was just the door to kingdom hearts.

Kingdom hearts is the heart of all worlds.

ahem kingdom hearts is a game made by square *shot*

 

its the door to darkness made of hearts.

Kingdom Hearts is the heart-shaped moon, the 'door' that appears in KH1, I think is the door either to the RoD or RoL, but I'm not so sure...
