I think they're meant to be Mileena and Jade in the foreground with Tanya in the background and Sindel in the far background. At least that's what it looks like to me.

I think they were just random Edenian Girls.

oh yeah and they just happen to be a green costumed/masked tanned woman, a purple costumed/masked woman, a dark skinned female wearing a yellow costume that looks similar to something Tanya would wear and finally a fair skinned woman with what looks like gray and black hair wearing a purple costume.

You're quite touchy.

I doubt Mileena would be that close to Kitana. You might have something on Jade, but she is wielding a bow and arrow and yes there is a girl in yellow but whatever.

And I really cant tell anything about the ladies further away.

if you wanna believe they are Mileena, Jade, Tanya and Sindel. More power to you mang.

sorry i didn't mean that to sound so dickish.

NP Bruv.

They certainly Allude towards the other female ninjas, and tanya.

To answer your questions, yes, yes, yes, and yes. It's simply an allusion to get the fans in a frenzy. Here's a picture from the comic...

Those are not Jade, Mileena, Tanya, and Sindel. They don't even have their respective weapons.

Kitana's outfit looks so boring compared to the other Edenian Resistance Fighters...

Giant handlebar hairbraids for a fighter?

Wonderfulllll.

When do you realize that Mortal Kombat isn't about logic? It's been hammering at your skull for years now and you still don't seem to get it.

One of them, the one in green is meant to be Jade. The others are just ordinary Edenian girls...or so I think.

Not unless Jade's skin's been bleached a few times, and then she got a major tan in the following games.
