The answer to your question, my dear friend, is Zero’s torso.
I’m fairly certain that all throughout 1994 I believed Zero to be female… so that’s a plus? Ironically, back then his sprite lacked those ambiguous green domes precariously fastened to his bosom. (Are they headlights? Is he an Autobot? If you have another explanation, Inafune, I’d be glad to hear it.) Assuming I couldn’t preserve Zero as a mechanical vegetable, our date would prove to be a short one. I suppose it’d be in bad conscience to suggest we “go Dutch” (no doubt an expensive last meal), but I figure I’d make out alright with a nifty buster attachment at the end of our evening (should I not already have one).
Jivatma feels that Iori Yagami comes off as “boring” (this won’t do), and exudes an acute superiority complex (not uncommon among villains), tending to drone on a lot while boasting the mannerisms of an immature, nigh-omnipotent being. Also, despite being reversed, Another Jivatma’s gender remains questionable at best. (Do you trust Falcoon?) Essentially, when I look at his alternate design, I can only envision a vainglorious, high-maintenance woman—an ice queen (potentially king), if you will.
Short Answer: I’d rather not give a manicure to the Fingernails of Darkness (much less anything else Falcoon has had his hands all over).
