Umm, what definition of Bechdel Test are you using again? Unless "Blechdel" is something totally different from Bechdel?
MJ is one of Marvel's earliest female characters to pass the Bechdel test. Other Silver Age female characters,
even heroines, like Jean, Sue and Janet, were often the sole women characters in their respective comics, making it hard for them to even meet another female character, much less have a discussion with them regarding something other than men.
MJ OTOH used to tease and humor Aunt May, Aunt Anna and even her rival Gwen, without bringing up the topic of boys or men. Later on in the 70's, she appeared in Ms. Marvel's debut title where she totally charmed Carol over with
her own personality separate from anything to do with Peter.
