if i were to make smokes moves they would be:
-a stun move where he blows smoke at the opponent and they are coughing and such
-throws smoke down and disappears (a little iffy on this cause reptile already has it in this game)
-if you don't want to make him a copy of scorpion, but still want him to have his old moves he could throw a spear/trident/harpoon thing behind him and it grabs the opponent from behind (like a spear teleport) and pulls them in front of (fromt he other side of the screen) to him
---or he could throw the spear/trident at the opponents foot and trip them
-since every other character has one, and he's one of the ones it would fit with, he should have a teleport where it's like nightcrawler, puff of smoke to disapper, then one to come out but instead of coming out of the ground like all the cyborgs, he should come down from the sky for a kick (he could do the uppercut, cuz thats how it was in the old mk's, but this is just for variety)
any other ideas??
