3 - dr poison is easily one of the most awesome and neglected supervillains ever. it's insulting. i decided early on that WWs principal foes would all be existing characters... and women. if WW is a role model for a positive feminine ideal, can't her enemies be equally strong models of a negative? her three foes have distinct personalities, motives, and bodies. only one of them has the typical va-voom comic body (cheetah), because that fits her rather vain, narcissistic and flamboyant personality.
i made dr poison freakishly lean and androgynous because she is one of the most self-negating characters in comics. there is nothing either soft or sexy about her personality. (although ironically, some people think that my DP drawings are a cheap attempt to sex up the character, so oh well...) she's covered in punctures and scratches and bandages because she does terrible things to herself, and she wears a minimum of utilitarian clothes because she doesn't give a shit about anything that doesn't directly aid in her overwhelming obsession. she has tattoos because she is a member of the ultra-nationalist japanese "black dragon" society, with extensive links to the yakuza (and yes, there was a real BLS which engaged in espionage and terrorism on imperial japan's behalf from the late 1800s to WW2). her hair is japanese cutie-pie because a) she is japanese and b) there is nothing more disturbing than something that should be cute and happy sticking needles in you eye. it's a matter of taste, but to me the rictus and trench coat screamed "if you hop a time machine to mid-1994 then i am going to scare the crap out of you". might as well give her twirly mustaches and a black hat.
i didn't give dr poison a specific age, but she is supposed to be pretty young. she is ruthless and callous in the way that only a young, rootless person with ideological nightmares can be. a sort of purified embodiment of totalitarianism, who doesn't care what she breaks or even if she survives. so you can imagine she and diana have a lot to chat about...
sailor libra - it is true, fortune is cruel!
batcookies - i would say don't pre-judge it, but frankly what do i care? that's sort of what the internet is for. and google maps.
