Basic, retarded, fun - like Dhalsim's bullshit only a bit easier to escape.
Blanka's bite range is simply sick, I think its actually larger than Sim's, but anyway... generally j.LK or early j.HP tick into bite does wonders if not abused too much.
Once you land throw you can do the following:
- j.LK > throw again xx repeat - this is obvious to get out of, but its one of those things that works because Blanka is so fast, even if you only get a second set of bites, damage is damage. BE CAREFUL, depending on where you are and where your opponent lands, you want to be sure that your j.LK is MEATY and the opponent does not have an opportunity to use a Shoryuken or other anti-air.
-j.LK > MP > throw – MP ticks nicely into throw, but you have to be close enough.....if not, you'll get standing HP. Still safe, but you wanted that throw!
-j.LK > MP > leap > throw - You can even add a leap in here which if you're close enough, will cross up. You don’t necessarily have to go into a throw, a combo or a tick could be a better option.
-j.LK > x-over j.LK > combo attempt - the second c.LK should crossover when your at mid-screen so make them feel the rage (rawh!)... you also have the option of repeated j.LK's if the first crossover attempt doesn't hit.
-Slide - hilarious, but it works, people get so paranoid over the j.LK and trying to stop it they forget Blanka can just low knockdown them and start crossover ball fun again. You can also mix this up with c.HK since it is a bit faster.
-Leap forward twice to crossup > throw/combo – this can be quite useful against characters which don’t have reversals.
DSP EDIT: One of the most effective strategies, I have found, is what to do AFTER a successful throw. Basically, if you finish the bite, you land before your opponent does. When your opponent is landing, try to do a meaty crouching FP. Depending on where you were when you landed (in the corner, midscreen, etc) the FP will either whiff, or they will block it. If it whiffs, oh well, you were too far away to do the setup so just chill out. If they block it but their body does not move at all, you are probably too close to do the throw setup I am about to explain. BUT, in about 50% of the time, the opponent will be pushed just slightly back from the blocked crouching FP. THAT is your opportunity: immediately do a jab horizontal ball when you recover from the FP. It will advance you forward JUST ENOUGH to land perfectly in front of your opponent WITHOUT having them block the ball. They will undoubtedly try to block the ball, because they fear eating it, and this leaves them WIDE OPEN for you to land in front of them and get a second bite! CONGRATULATIONS, you've just done about 50% damage in only 2 moves! In addition, after the second throw you can try to do the same thing again, or you can walk forward and try to buffer into leap setups, or you can try to crossup. It's your ballgame.
