Works on Honda, Makoto, Gouken, Dictator, Dhalsim, Juri, Rufus. However Juri and Dhalsim can walk backwards if they guessed that the super was a crossup and don’t block the first kunai. And BTW before you ask Dictator and Dhalsim can teleport out but they are taking a huge risk because they won’t know which way they are teleporting.
To perform the crossup you must take a slight step forward before you jump
There might be more setups off of other knockdowns; I will keep this thread updated with any new info.
EDIT: It works on shotos too you just have to take less of a step forward then I did in the video. Ryu and Ken can only get out by doing an ex dp in the opposite direction (they can’t auto correct).
