I am not familiar with the character, sorry. Anyhow, about the fake. Names would be good, Sub-Zero having less like would be good too. I dont like the sprite at all, it just looks... really weird. I don't know.... And the move itself looks dull.
Uhh, boring is the only world that comes to mind. It would have been better if we could see a frame furthur in the process of the move. This looks like Kenshi's fatality but at the beginning when nothing is really happening.
The assassin sprite doesn't really blend into the picture either.
