I honestly have doubts if that's Jade because she in the prison cell in one of the stages. But I think it could be Jade because the woman is wearing green and is black. But if Jade is in the game I'll be ecstatic and she better have her staff back too. But back on topic, I think Fujin and Drahmin might be hidden characters if Jade is one but I think it might be Tanya's alternate.

P.S.I like Tanya and Jade but I hope it's Jade.

I think it's Jade for a few reasons.

1. Once you unlock her she could be removed from the prison cell.

2. In UMK3 they had Cyrax in the background of Jade's dessert. So her being in the background could mean nothing.

3. I doubt they would be dumb enough to make Tanya's alt outfit the color green when the color green is clearly Jade's out of all the female cast. It's like giving Scorpion a green outfit for one of his alt. outfits when everyone knows that is Reptile's clor. Or giving Ermac a blue outfit when we all know that is Subby's. Almost all characters have a certain color that belongs to them. Only a few have not had certain colors, like Kano.

I think its Jade becuz shes not as dark as Tanya (tanya is more like jax color) and boots are the same ones that can be seen on the prison stage...yea, its her....i hope

I think that's Jade... b/c Tanya has more of a brown skin... and Jade is more darker than Tanya, just my opinion though....

Jade seems lighter in the prison cell in my opinion. But somehow the colors are matching, so I'll stay with Jade. As for the others, I think they're gonna make an appearence.

I think it's Jade since Jade is lighter then Tanya and that woman is not much darker then Mileena.

Jade is has the skin tone of a Spanish person, pretty much tan. Tanya is more darker, say African or if you will black.
