In an act of desperation against rose I did a DF dive kick and and immediate raw ultra 2. The dive kick hit and much to my surprise the ultra landed as well. I thought she must not have been blocking but after the ultra it said 3 hit combo.
I went into training and kept trying with auto block set and I figured out how to land it off a DF kick. It doesn’t even need to be a counter hit which is great. Spacing is critical which makes it tricky. Your kick must land low for this to work. I had Dudley as my dummy and if the kick hit his waist ultra 2 landed every time and the input is so easy. Here’s how you can try it:
Place the dummy in the corner
Position yourself so you have 2 floor blocks between you- dummy is on block 1, 2 blocks away which puts you on block 4
With your foot on the line closest to the dummy do MK DF immediate kick then up up kkk. No need to cancel teleport or anything fancy.
I don’t know if this spacing will work for all characters but the kick will land on dudley’s stomach/hip area. I’m not sure how useful this will be in a real match but it might come in handy for punishing certain moves. I’ve done it 5 times in row with the ultra landing every time.
