Better Crossover into a Mortal Kombat game if it ever were to happen: A Tekken character or a Street Fighter character. (who?)

Blaze
Mileena or Kitana

Well as we just skipped ill answer both questions
Streetfighter and it should be Blanka (he just sorta fits the mood)
And Kitana is waaaaaaay better than Mileena for obvious reasons
Should Noob also recruit Sektor and Cyrax into his cyborg ninja army.

yes recruiting them would add a whole new dimension to the mk storyline.
try this one out:
should kai return in MK7 in attempt to bring raiden back from the dark side since kai accoriding to his ending in mk gold he will be the next protector of earthrealm?
OR
should fujin return in MK7 to bring raiden back to restore the merit of the Gods reputation in Earthrealm?

Fujin since he is also a god (and possibly the current protector of Earthrealm. We're never told for sure)
Shokan or Centurians?

centurians, I love those creatures...although in MK a Shokan looks cooler
Seeing Kitana ending up with liu Kang, or alone?

they'll end up....its inevitable they'll be king/queen of edenia
battle of the clans....Reptiles clan VS Barakas clan who do you think would win?

Reptiles clan (if they're somehow resurrected)

Shang Tsung or Shinnok

shang tsung. shinnok didnt have enough playtime to be considered as dangerous as shang.
which fatality is getting played out? heads being decapitated or bodies blowing up
