Why does Blanka ex rainbow ball break armor sometimes?

Like the title says. I was playing a blanka online yesterday and when blanka did a ex rainbow ball i focused it but it broke my armor. Why does it do this sometimes and not others?

If he does it as a reversal, it will have an armor break property.

Thanks man, Online forums sure are useful.

Every special in the game (besides fireballs) is an armour-breaker if done as a reversal. You just don’t see that come up as often as you might think, since most attacks which people would use in reversal situations are multi-hitting or armour-breaking already anyway.

Cool, Thanks for the info. I had no idea that was the case.

All knock-down specials actually.

upball breaks armor on reversal as does hayate. It doesn’t have anything to do with the move knocking down.

Really? I’m thought it even said knockdown in the instructions. Oh well, you learn something new everyday.
