Ok, wow. Did some testing and research and figured this c.hk vs. EX SBK thing out.
The TL;DR Version is this - c.hk has an insanely low hurtbox, and EX SBK has a pretty high hitbox.
The reason EX SBK is losing to c.hk isn’t because it isn’t fully invincible. It’s because c.hk is so low the ground it is actually entirely under EX SBKs hitbox. So EX SBK is invincible for 8 frames, but c.hk just stays under it completely and then hits it when it becomes vulnerable again.
Timing test to confirm:
Set Chun dummy to wake-up EX SBK and back recovery.
Do s.lk -> mp xx MP Peach, dash, c.hk
With this timing, c.hk goes under EX SBK every time and will CC the reversal. No other Mika normal is even close to this low to the ground. Everything else you can do will get hit (trust me, I tried).
Seriously though, look how low the hurtbox on R. Mika’s c.hk is. What you’re looking for is the green outline boxes, not the yellow and red ones. The green part is where Mika can actually be hit. I knew c.hk was low to the ground, but that is really low. None of her other tools come close.
EX SBK, on the other hand, has a really high hitbox. c.hk just stays right under it until the invuln ends, and then gets clipped (note that EX SBK doesn’t even HAVE a hurtbox, because it’s invincible, but in the later frames when it loses invuln it looks more like HK SBK).
If you didn’t already know that this hitbox reference resource existed, btw, it’s an awesome reference source.
Use it.
We should actually explore this a little more, because I bet you there are more practical ways to use this. I still maintain that the risk on c.hk (eat a combo of their choice on block) doesn’t justify the payoff, so I still wouldn’t recommend leaning on it, but it definitely does eat EX SBK for breakfast if timed correctly.
Edit:
Ok I figured it out for real this time. c.hk VTC vs. Chun on wakeup will beat EX SBK clean with correct timing, CC AND combo (if you do neutral VTC), although the V-Trigger hit removes the hard knockdown property of the sweep so they can tech. However, it is also safe on block, so you can’t be punished. There you go, c.hk xx Neutral VTC (no delay) > EX SBK threat, even on block.
Edited Edit:
Bahahaha delayed VTC comes out slow enough that it doesn’t land until after Chun wakes up from the CC knockdown. Ok, go keep working on this if you want to.
c.hk xx Delayed VTC (any direction) will crush reversal EX SBK clean, is plus on block (at least +5, it’s actually a true blockstring into s.mp), and gives you a delayed VTC mixup regardless of whether it hits or is blocked.
Godlike.
