Shes a decent Character, I just don't think she has any MAJOR importance to the game, other than to die by Jade hahaha

I hope she doesn't! That would suck!

Tanya is improved a lot in this game than from MK4. I personally thought we would never see her back, so when I found out she was in MKD I was intrigued.
She is an interesting character, but I'm afraid I have to agree with whoever it was above and say she doesnt have any real significane in the games, in terms of future appearances. She is important in Deception as she I the Key to Onagas entry of Edenia, but apart from that she doesnt have much relevence, unless they bring Kitana and Jade back and the rivalry continues.
I dont see Tanya's ending happening, but maybe Jade's wont happen either.
I like Tanya's weapon in the game and her fighting styles, specials/finishers and look are decent too.

She is the most interesting character to me. I like her type of character and the role she plays. It just so much better than a boring do-gooder who just tries to be nice all the time. I think she has a lot of significance in the games, since who else in the game is a good person turned evil out of self interest. Kira is a great new character but she is just so formulaic, Mk has always had Kano, Kabal, Kobra, Mavado in the same gang (Black dragon) so many of the evil characters are so similar, Tanya is at least original and fresh... plus she plays great in the game. Definately one of the more interesting for me...
