What I would really like in MKDA is that after u win the game with every character u get the "Mix ur own fighter" Choice...
I would like that to "resucitate" old MK characters I love that may not make it...

What I have in mind is something like what you were able to do in MK4 with the gameshark. Grab a person's body, maybe tweek it a little and add other fighters' moves.

For example, if I want humn smoke what I would do is: take Sub Zero -since he has that "smoky" look because of the ice vapor, if possible make him gray, add scorpion's spear, add someone's fighting styles and weapons (U can choose wwhich ones...) and then add drahamin's teleport punch...DONE Home-made human smoke!
Or for Ermac grab Scorpion, make him red, and add Kenshi's moves.

A variable for this option would be t have all these characters already prepared and have a cheat to unlock them...after all... they are just a mix of memory alread there... t shouldn't cost much space...
