And Bat-woman and Superwoman:
And I though this was a really cool idea that should be extended to a comic alternate timeline/world where all the superheroes are of a different gender. So instead of Ironman, there is Ironwoman (Toni Stark). Captain America is female supersoldier Sheila Rogers. The X-men are X-Team (or similar, mainly to avoid confusion) consisting of female Cyclops (Susan Summers, sister to Alexis Summers aka Havok), female Beast (Henrietta McCoy), female Colossus (Illyana Raputin in a strange twist), male Emmit Frost (formerly the White King), male Karl "Panther" Pride (with female Lockheed), female Wolverine (Jamie Howlett, goes by Loran), female Bishop (Lucy Bishop), female Nightcrawler (Katarine Wagner), male Psylocke (Robert Braddock), Icewoman (Debbie Roberts), male Rogue (think big Southern football player), female Gambit (Renee LeBeau), female Archangel (Katherine Worthington), Sean Grey (aka Phoenix, Marvel Guy), male Storm (David Munroe), and, of course, Lady X (Cassandra Xavier!).
Bad guys would get similar treatment female Juggernaut (Kara Marko), Female Magneto (Erika Magdelena Lehnsherr), Scarlet Warlock (Wayne Maximoff), and male Mystique (Draven Darkholme).
How cool would that be?
...Spidergirl isn't from some alternate universe, she is Spidy's lil' girl. A true comic fan would know that.
