thoughts for ice moves:
ice aura: raising it underneath your feet like scorpion's fire, only the result is freezing you , obviously
ice kiss: instead of the iceball , or ice wind, a little twister of ice coming at ya to freeze you instead of some ice in the form of the kiss
ice shower: subzero's, from mk3, coming from the sky
ice daggers: projectile like skarlet's, no freezing, just throwing daggers on you, frozen ones
ice shield: protection from projectiles
ice breaking (grab): breaking a ball of ice on your head and then perform the grab with a kick
ice crystal: making a crystal of ice (kinda like kryptonite was shaped) and shoving it up your stomach
xray thought: blood on ice, she tackles you on a layer of ice with force, shoves an ice crystal in your stomach while you're down, then picks you up and shoves another crystal of ice inside you from behind to bleed even more, before kicking you away on the back of your head
that's all that comes in mind atm, if anything else does I'll edit or repost. btw, it's pointless to ask people not to "joke" about frost being a subzero ripoff, there will always be people who will make cheesy "jokes" about it. any type of character has potential to evolve and have different moves than another one if they use the same thing, in this case ice. I'm sure NRS can think of moves to make Frost unique this time around
