Vs Fang:
You can mp.bolt any of his non-ex air poisons on reaction so try to stay at least within mp.bolt range. You have a ton of leeway in reaction against all but his lp air poison, lp can still be beat clean on reaction but if you’re reactions are a little slow, it can trade some times, having said that, his air poison is still -7 on hit while mp elbow is +2 and puts you right up in Fang’s face where you generally want to be, so even a trade is not necessarily a bad thing. His ex air poison drops one of the poison balls in front of him so it can be punished by an ex.bolt on reaction, but not by any other version of bolt as far as I can tell.
His “Take your poison” v skill recovers REALLY fast so while it is punishable with mp.bolt too, it basically has to be a read, very difficult to punish on reaction. Since mp.bolt itself IS punishable on block, I’m not sure its worth the risk unless your opponent is being really obvious with his v skill timings. Since the poison does not interrupt moves, however, if your close enough you might consider attempting ex sunset wheel on reaction and if that starts luring him into jumping after his V-skill when you have meter, depending on the distance you may be able to catch him with hp.bolt instead.
All of the non-ex poison mines are punishable on block. The light version ends with a short built in back dash, that moves it outside the range of cr.mk, cr.hp, or st.hp, HOWEVER, it is -9 block and at all the distances I’ve tested it at cr.hk WAS able to punish it on block. The medium version is less minus on block at -8, but lack the jump back and has negligible push back, allowing st.hp or cr.hp to reach it at all ranges that it could reach you at (as far as I can tell). The heavy version is the worst version for him to do in your face since it also have no built in back dash or significant push back and is -10, making it very open to whatever punish you’d like (I prefer cr.hp for the 10 extra damage as st.hp doesn’t seem to get a crush counter out of it).
As far as him using them as actual mines as a wall for his air poison, a mine into air poison combo can be beaten by EX.bolt as long as he didn’t use the ex version (since that is the only version that leaves a 2 hit mine, his light version is also two hits but does not leave a mine behind)
His double fist slide forward attack hits twice, so no ex bolt here (though the start up is fast so you’re probably not going to do anything on reaction to this anyway). They can also be spaced to be safe. However, if he does them too close, all of the non-ex ones very minus (-9, -10, or -11 depending on the strength) so pretty much every normal but st.hk is a potential punish option. From my tests it seems like EX sunset wheel reached even on safely spaced ones so while not a true punish, its something to consider, and because he is so minus, using dash or lp.elbow if you think he might be hitting a button to get in isn’t a bad option. lp.bolt is 13 start up, and his light punch version is -11, hp is -10, and he doesn’t have a 3 frame normal, so its a pretty good frame trap BUT if you wiff even against his -11 version, you’re effectively at -20, so make sure your lp.elbow can actually connect on block unless you’re certain he’s going to hit a button. One final note, it does take him some frames to retract from his attack, so there do seem to be some distances at which a st.hp or cr.hp will miss, but, say, a cr.mp WILL connect on block, do to being fast enough to catch him before he retracts out of range.
His slide(roll) move, as previously stated, is NOT throw invincible, so you can grab him out of the start of it on a read. As far as I can tell laura’s lk.SSW can grab all of his non-ex versions after the animation too (mk and hk versions seem to wiff). His ex version puts him outside the range of almost everything most of the time (occasionally I can just barely reach before he recovers with a cr.mk) once completed, but ex.SSW is an option, and on reaction, assuming he didn’t catch you in the middle of something, I find that if you immediately start holding back you give yourself more time to grab him before he passes through you. Personally I go for a normal grab in those situations since if I’m late and he crosses me up, it messes up the SSW input, and from what I can tell through tests, it looks like he can’t tech normal grabs during his slide.
