Okay, an almost impossible to do combo,
with Benimaru, execute a jump cd, call seth, before you hit the opponent with the cd, if the word counter appears then the do the qcf p, lightening fist thing, it will be four hits in the air, then seth will hit the opponent up and you can the do the max sdm. It is a very complex combo, to do, I have only done it three times, in a match, but in practice mode it very easy, since you can set the counter function on on. You just have to find the exact spot.
You can do other wierd but useless combos too, like with benimaru's regular hop, c you can do the down d, dhalsim drill wannabe thing, same with b, but also on your way up, with jump c, you can also do the lightening fist, I really can't explain the timing on how to do it. The drill move doesn't combo with the c or b though, it is just a move you can do after the fact.
But is cool when, you hit the opponent with the c, then seth comes out, then before the opponent can be lifted up, the drill hits the guy, maybe two or three times, and then as he is falling down you can execute, the super.
I wish I could show these combos in videos. All during matches of course, I hate combo practice on dummies.
I'll reply with some Jhun combos later, I have got to go to work, The combo requires counter mode, and counter again.
