Jade's in MK:D. This has been mentioned in several places already.

I don't have to look at the pic to know your talking about the prison stagen... old news.. but hey your new, so your forgiven .. welcome though

I have absolutely no idea about her being PLAYABLE in the game, but it is likely not... *crying*
But yeah, it MUST be her in the cage there...
I think, they took some characters, who's not playable in the game and just made them appear on the stage!

well my idea is this: boon said that every character that ever apeared in a MK game will apear in Konquest mode.. so for not letting all the new models go to waste they add the models of some fighters to the backgrounds.. I wouldn't be surprised if the aged Shang Tsung in the background of the courtyard stage will also be seen in Konquest.. hope their will be others..
