Ok now lets talk launchers. While she has nothing insane like EWGF, her launchers are great.
df+2: Nina’s fastest launcher at i15. It is mid, safe, and can go under jabs. The drawback is that that it does not launch crouching opponents unless on CH just like the rest of generic df+2s that a few characters have in tekken. It is still a great move since mid launchers that are safe aren’t very common in tekken, especially at this speed. It doesn’t have the greatest range, but it’s good enough.
b+1+4: her 2nd fastest standing launcher at i16. It’s m,m, has great range and launches both standing and couching opponents. However, it is launch punishable on block. The main use of this launcher is as a whiff punisher and against moves that are -16 on block. You can’t just throw it out there.
db+3+4: geyser cannon, qcb+k in SFxT. It is mid and has huuuuge range. It is a bit slow at i19 and is also launch punishable on block. Its main use is for launching bigs whiff for crazy juggle damage.
uf+1: Nina’s main low crushing juggle starter. It is completely safe on block and also launches crouching opponents unlike df+2. However, it is quite slow. Still a great juggle starter.
ss+2: mid launcher from ss. It comes at i14 from side step and is great to punish the opponent when you side step a move successfully. This move made me love Nina. You side step a move then BAM launch! Sadly it got nerfed a bit in TTT2 compared to T6 as it used to be -12 on block, but now -14. Learn how to use this move properly. It’s amazing.
Now for her block standing punishers:
-10: 1,2 for 22 damage and +frames on hit or 1,4 for 29 damage and -6 on hit.
-11: 4 for 20 damage and +8 frames on hit or any of the above options.
-12: b+2,2 for 34 damage and +2 frames
-13: same as the above or df+1,2 for 30 damage and +2 frames, but it has followups if you want to go for mix ups. I’d say stick with b+2,2
-14: she has tons of options here, but the best two are: df+3,4 for 45 damage and +7 frames or f+3 for 39 damage and KND/wall splat
-15: df+2 launcher or if it doesn’t reach, ff+2,ff+3 for 54 damage
-16: b+1+4 launcher
-19: db+3+4
For couching/while rising punishers against low moves:
-10: d+1 very low damage, but it’s not the majority of the cast has anothing else
-11: ws+4 for 20 damage and +7 frames
-12: the same as above
-13: ws+1,1+2 for 43 damage and KND/wall splat
-14: the same as above
-15: ws+2 mid launcher
For whiff punishment, your usual options are df+2, b+1+4 or db+3+4. From side step, ss+2 is great. In order to get results with Nina you have to be great in whiff punishment and movement since she does very high damage from her launchers.
I only learned about frames and such last year and it really helped me understand how things work in tekken.
Hope this is useful (^_^)-b
