You could easily make some shit up for Noob.
Cage's stun double is pretty bare bones.
3 variations.
Shadow clones
Clone tackle, clone slide, clone throw from UMK3.
A bunch of clone normals similar to MK9
Weapon variation with a scythe similar to MK4. Generic, but effective, and you can do some cool shit with scythe twirling.
Black ice
Cyromancer powers, but with a neat black visual effect on the ice.
Slide, ice shower, MKVSDC grave teleport, polar blast from mythologies.
Non variation powers could include his regular teleport, disabler, ninja stars from MK4. Maybe portals, but those are always a waste since they suck.
Jade however, IDK.
Really have to scrape the bottom of the barrel for her.
Sindel or Skarlet would be better choices.
