What does Mercy Graves count as? Supervillainess proper? Possible love interest? Disqualified for having an animated origin?
That’s irrelevant, since this fight is a no-warning no-prep fight, they essentially DID end up getting rushed into it, even if they didn’t rush into it themselves, thus the one with the most experience in that sort of fight would win, so the fight is in Lois’s favor 
I can’t believe I forgot Bethany C–not only a bruiser, but, as drawn by Bob Layton, unbelievably hot. I retract my vote for Lois and throw my support to Ms. Cabe.
Since in any real fight, the most important thing is mental, i.e. the willingless to inflict damage upon your opponent, I have to think that Jean Loring would be the last one standing.
That chick is crazy.
Stole mine! Gotta remember, Jean Loring is probably the only superhero girlfriend/wife/ex-wife who’s ever killed another superhero girlfriend/wife/ex-wife.
Although now, of course, she’s orbiting the sun sans space-suit…
