User blog comment:Kurare/Yoruichi Shihōin's Zanpakutō theory/@comment-24113610-20140821173926/@comment-24113610-20140825221731

Darkhunter if you read my second comment you would have seen that I already corrected myself about Yoruichi being powerless in cat form.

I don't wanna say that her zanpakuto is "likely" lightning. Yeah, we've only seen her use Hakuda and her lightning-based shunko. But that's not saying much bc it's as you said: Soi Fon's shunko is wind-based but her zanpakuto isn't. And it's hard to say if it's even a poison type because the bankai has nothing to do with poison unlike Mayuri's zanpakuto. I would call Soi Fon's Suzumebachi a melee type with the general idea being "A sure kill." The shikai takes two hits while the bankai only takes one(hence the upgrade).
