After a parry you can do 9k into 8k for a juggle of your choice (3pkk2k works on lighter characters). The 9k is a lift stun so the 8k cannot be held if you do it fast.
edit: I've tested this on highest stagger escape as well. Computer still can't get out of the combo.
Found this combo for mid kick hold: 3pkk. It will cause a backturned crumple stun that I'm pretty sure can't be held or escaped. launch with 8k into a juggle. 9kk into 3pp6pp works on most characters (minus Bass, Bayman) for 98 points of damage in open space.
What's everyone using after a mid kick hold? The only guaranteed combo I could find was 3k p+k into whatever.
I tried 236p, 3p, 8k into a juggle on the cpu and it worked, but a human being was able to turn around before the first hit. Weird.
