it is black with a dark crystal near the end.it is NOT the heart opening keyblade from kingdom hearts 1
You cant get dark form, but the more you use other forms the more chance of you forming into it. Also specific boss battles have more chance of forming the dark form.
Riku is seen with the Dark Keyblade when Sora talks to him in Hollow Bastion in the original Kingdom Hearts game. However, Riku changes it when Sora fights him.
It isn't something you get, Riku has it as a sleight already, but only when you enter Darkness Mode. Along with that he has Dark Break and the rare Dark Aura, see what works best for you!
Kingdom Hearts is an entity formed from the gathering of hearts. Hearts gather into Kingdom Hearts when Heartles and Nobodies are vanquished with the power of the keyblade (otherwise the hearts would just reform into Heartless again). Kingdom Hearts was originally thought to be a dark or evil entity, but as Sora learned from his adventures in the first game; "Kingdom Hearts is light".
Your Kingdom Hearts might be different to mine, but I think the one you're talking about is Oblivion.
The World That Never Was
I had a dream where I went to the kingdom hearts worlds and had my own adventure it was pretty interesting.......and a little dark at times X3
There is no such thing as a dark crystal, although you might be talking about lucid.

No, the darkness is just that; Darkness
Once you defeat sephiroth at the dark depths
