No. You cannot cancel the overhead. I don’t know why, but that’s how it is for balance purposes I guess.
And for Blanka… Well there’s the pro Blanka and semi-pro Blanka.
Pro Blanka players will anti-air ball you if you try to jump inside. And if you try the cross over, there’s the electric crouch move you need to watch out for. If you try to link, you also have to watch out for the electric reversal. I usually play similar to how Mago does vs. pro players and just zone the heck out of him because a misjudged TK or badly timed TS will get you an accompanying handshake as you walk out that door.
As for the Blanka balls, depending on the distance, you can do (HK) Low Tiger Shot immediately after he hits you. Then he’ll do a few things…
Block: Throw another Tiger Shot
Jumps straight up: Throw another Tiger Shot or Kara cancel TK/TS.
Jumps forward: sHK, F+HK, or TU if he least expects it.
Jumps backwards: This is kind of funny because I’ll take a few dashes forward and when he comes back down he’ll sometimes land on the Tiger Shot because the screen moves his way lol.
If Blanka does his Ultra, block low because Blanka actually slams the floor with his hands and electrocutes the floor for a good distance, then block high as Blanka is coming down. The next block is dependent on preference so I usually block low because this gives me quicker motion for Ultra… and empty Ultra hurts… You can time your f+HK but sometimes it’ll whiff for some strange reason. Just remember that the second part of Blanka’s Ultra, after the overhead, there’s gonna be 4 BLOCK string. After you hear 1,2,3,4 execute your Ultra and it should land. So basically there’s 3 parts to his Ultra.
1.Low
2. High
3. Any block
If you’re low on health and he’s going to Ultra and chip you to death. Wait for Block #2 (the overhead) then immediately execute the Ultra command and hopefully you’ll Ultra him while only taking 2 chips.
Off topic: I love how Mago observes the Blanka and does sLK>LTS to chip Blanka after he jumps just to let him get comfortable with jumping in after Blanka balls. Then at the critical moments sHK and TU. Haha, gotta love behavior masking with repetitive moves.
