if they are to have reversals i would like the system to have normal reversals for punches and kicks, like if someone were to punch u press up and the reversal button and the kick would be down and the reversal button and signature reversals would block punches or kicks depending on the character if someone to at you you press two buttons instead of one or the direction but to reverse the attack and add individuality to a character.

examples

Kano- grabs the punch and reels his head back then smacks the opponent in the face with his metal plate on his head and you hear a loud CLUNK!! then the opponent falls to the ground leaving him vunrerable for another attack

Johnny Cage- the opponent kicks at him and johhny cage grabs his leg under his arm and says "That's all you got!?" then uppercuts the guy under the chin making him fly back half of the screen distance.

Jax- jax would grab the opponent by the neck and the opponents leg say the famous gotcha "GOTCHA!" then would launch his in oppponent in the air reel his iron fist back and give the opponent a big punch sending him to the other side of the screen.

Sub-Zero would grab the opponen's fist stare the opponent in the eyes and freeze the opponents fist making the opponent hop about grabing his frozen arm in pain leaving him vulnerable for another attack, like the ice puddle move.
