Sub-Zero in mk9 he was just too defensive and sluggish just a random string into ice clone, slide or throw ice ball and do the same weak-ass combo over and over. Now hes The ultimate ice ninja able to throw the fucking Ice clone at ur face or detonate it ,build a ice shield , Ice Armor/aura and has a freaking ICE HAMMER.. And is personality is now more like Noob Saibot(not saying he IS bi-han but..).
Scorpoin even though hes like the trademark of Netherrealm studios he was pretty weak in Mk9Hated him in injustice too. But God dam they made him such a beast in mkx he can now cancel all of his teleport, Hes Inferno variation With those Demons and that Solomon Grundy low grave root, love the animation of a fucking demon holding you like" don't mess with the Netherrealm".
Hated Kano for his dumb design, weak combo potential and the spammable air ball people would just be throwing out like they didnt know its punishable...Well in Mkx hes now really a Badass cyborg with Fulgore-like Eyelasers and sick grenade combos.
Quan chi was an interesting character in mk9 but boring gameplay. In MKX he finally looks and plays like a Sorcerer.
Lui Kang Omfg the bruce lee clone although i love bruce, in mk9 he basically only had one string which you just did over and over with no variety just " wtaah uaah quaah". Well now in MKX with those Martian orbs , 5 frame punch and bicycle kick leaving you standing oh lord.
They have been On point with all characters
