If you have one bar and land a focus attack you can do this and it’s simple. Don’t know why I haven’t seen it more. I recommend you only use this occasionally (maybe once a match) and in a high pressure situation where the opponent is likely to throw out SRK or other wake up moves.
Focus Attack > Dash Cancel Forward > Quick Focus Attack (level 1) > Dash Cancel Forward > EX Demon Flip
So basically you focus attack to crumple, then dash up, focus attack them again quickly, dash forward again so you’re right in the opponent’s face. This usually causes them to freak out and throw out a Shoryuken, Throw or whatever. As soon as your dash ends you can EX Demon Flip and with the invincibility frames you will go right through most moves. You usually land on the other side and can punish with a full combo. The two Focus Attacks followed by a big combo will get most characters close to stun. I like this one because it looks like you’ve messed up your input and most opponents will just throw out their strongest move or command throw and whiff.
I can’t tell you how many times I was able to turn a whole match around from one simple focus attack. Throw in the mix up potential of Crumple > Dash Forward > LK demon flip over them > Dash under > Combo.
