No meter midscreen:
212, jk, sd, rc, s4 (or 32), ss. It deals 29 or 30% dmg IIRC.
No meter corner:
212, njp, jk, 212, 321+3. It deals above 30% IIRC.
1 bar midscreen:
b311 or b22, ex ss, njp, jk, sd, rc, s4 or 32, ss. It deals around 42% dmg.
1 bar corner:
212, jump back 3, ex sd, trap, 321+3, (opponent will fall to trap), stealth, sd, uppercut, 321+3. It deals 47% dmg. I usually go for the trap setup, but if you wanna go for damage this combo is practical, flashy and easy to do so. Only tricky part to do, is the cancel from the jump back 3 to ex sd.
2 bar midscreen:
b311 or b22, ex ss, f1, ex sd, close trap, rc, b2, back ss, sd, s4, ss. It deals 55% dmg IIRC.
2 bar corner:
b311 or b22, ex ss, njp, jk, ex sd, close trap, 32, detonate, stealth, sd, uppercut, 321+3. It deals 52% dmg.
There are much higher combos with Hunter Predator but these are the ones i m currently using during matches.
