Cyber Sub-Zero can punish string gaps with his B2 overhead/backdash attack. I've posted a video example as a frame of reference. This was orignally brought to my attention by @SaltShaker and I felt that this tech deserves its own thread (much like the Unbreakable string gap punishing thread for Parry and EX Parrry). I will be updating this list as often as possible.
Cassie
B12 * 4
Goro
B12 * U2
Jacqui
233 * 4
Raiden
112 * 2 (might trade if not timed properly)
B112 * 2 (might trade if not timed properly)
Jason
F21+3
Tanya
Delayed Rekkas
Alien
Delayed Rekkas
Liu Kang
FBF4 (non buffed) * Parry
FBF4 (non buffed) * DB2
If Liu Kang is buffed, he'll be able to block safely, but a Drone Enhanced B2 will leave you +2
Sub-Zero
Any strings canceled into Parry
Smoke, Sektor, Cyber Sub, and Cyrax
B3U4 This move has a gap after the second hit. This is full combo punishable by the whole cast.
Also, just a heads up, you can actually punish Goros B12U2 with standing 1 for a full combo.
