okay some of these combos i found online and some i came up with...
Li Mei
40%-8 hit
in kunlun dao: U1, D,B4 F,F2
32%-5 hit (my fav combo w/ her)
in lue he ba fa: B1 D,B4 U1
36%-6 hit
in kunlun dao: U1 D,B4 2,B3
in MK
A i absolutely hated Li Mei but they really improved on her this time around. sadly she is by far not a high damage charater but the good news is she can easily air juggle for a very decent amount of damage. stay in either lue he ba fa or kunlun dao stances. always go for the launchers or the carnival spin (F,D3), her regular ground combos don't do much damage at all. if you are having a hard time getting the launchers in go the throw.
Liu Kang
29%-5 hit (not much damage but it looks awesome)
in jun fan: 2,B1 2,3 D2
43-45%-12-13 hit

Liu Kang imo is the juggle king in this game. first off jun fan style rules, at first i hated it and thought "they just renamed jeet kune do". even though this is still true they made it better this time around. most advanced liu kang players are going to want to stay in jun fan most of the fight. most of the fight you will want to look for an openning to get a B1 (wich opens up most of his high damage combos), if that doesn't work mix up B3 and the throw. if you land the throw immediately shoot a low fireball to keep them on their feet. if B1 still doesn't work try going for 1,1,F2. there are many more variations of the combos i posted for liu kang and if you take liu kang to practice mode and try them out you'll be surprized how many air juggles he has.
Jade
42%-12 hit
in fan zi: 2,2,1,CS,4,CS,1,U3 2,1,U3
44%-11 hit
in fan zi: 2,2,CS CS CS 2,2,1,CS,4,CS,1,U3

49%-11 hit
in bojutsu: 2,1,U3 CS+2,2,1,CS,4,CS,1,U3
54-57%-10-9 hit (to do more damage you must miss the first hit of the combo)
in bojutsu: 2,3 CS+2,2,1CS,4,CS,1,U3
jade might just be the best character in the game. she is definitely top tier...easy air juggles, high damage, and good useful moves. she's the total package. her only downside is that she doesn't have the best teleport in the game!!
scorpion
34%-9 hit (this such a cool looking combo)
in hapkido: spear 2,3,U4 3 CS+D2
35%-10 hit
in hapkido: spear 2,3,U4 3 4,U4
38%-12 hit
in hapkido: spear 2,3,U4 3 2,2,CS,1,B1
44%-9 hit
in mugai ryu: spear F1 Cs+2,2,CS,1,3,3,CS D,B2
50%- 10 hit
in mugai ryu: spear F2 CS+3 2,2,CS,1,3,3,CS D,B2
scorpion MK
has unbelievably downgraded in my opinion! he was so much better in MK
A. he no longer has an infinite and his air juggles are really hard to time. he does moderate damage and is in no way a top tier character like he was in MK
A. his best style obviously is once again hapkido. always try for a 2,3,U4 launcher in hapkido. his new teleport kick is useless .instead use his flip kick which has way better recovery time than most people think and if it is blocked throw the spear at them. once they catch on and start blocking after the flip kick summon hell fire on their ass! too bad they didn't keep scorpion as badass as he was in MK
A. maybe in mk7?! that's all i have for now...sorry my post was so long!
