OK, this is a thread for all ideas and speculation on the fighting styles and weapons for new characters and returning characters. With that said, here's my ideas on some of the fighting styles and weapons for these characters:

Sindel:
Crane- I know that Shang had this style in MK:DA, but the style suits her more, as it is a martial art of elegance and Shang isn't elegant.
Whip- I know it's a rip-off of Ivy from Soul Cailbur, but hey, it's too cool to pass up!

Scorpion (I know, he doesn't fit the criteria, but I want to change something)
Spear- The Ninja Sword needs to go, Kenshi has the Katana, and Scorpion would not only be more unique, but the spear is such a cool weapon!

Baraka:
Tiger- Seeing that he is uber-aggressive, Tiger suits Baraka the best. Strength is the key in this martial art, and I think Baraka is the man for it, even though Ermac might have it (Look closely at the screenshot of Ermac attacking Noob)

I'd love to here more suggestions, please feel free to post!
