What I mean is, if a fighter is fighting Sub-Zero and Sub-Zero tries to freeze him and his opponent jumps out of the way, or side-steps too late and his hit partially, that only the body part that is hit gets frozen. You could be allowed to deepfreeze certain parts of the opponent as well, but based on the enviroment will evaluate how long it takes for the ice to melt.

Or if Kung Lao throws his hat at his opponent and he tries to dodge it, but is still nicked but the blade, he will bleed from that wound and it can be any part of the body. And instead of the hat reapering on Lao's head, the hat can either be picked up off of the ground (by any of the fighters) or it can be retrieved by pulling it out of his opponents body.

The same goes for Scorpion too. If he does his hellfire move, the place where it was done, should remain on fire, or the ground can be smoldered. And the effect and amount of damage done to the aren, is based on location as well. As for his spear, it should be able to insert various different parts of his opponent.

If you need mroe elaboration, just let me know.
