I think Donna's two favorite heroines are probably Supergirl and The Invisible Woman, so I helped her put together a costume for Sue. I wasn't going to be Reed or Johnny or Ben, so I had to come up with some way to be in the picture with her. Besides, Marvel needs a lesbian couple, they've got half a dozen gay male couples but no gay women? Really?
That is very surprising. I would think with a high male demographic with comics that they would go for lesbian couples. I know I'd rather see two women together than two men. The latter (to me at least) is boring to watch. That made this pic with Reese and Susan a particular treat! I'd love to see a series with these two!
Supergirl is also a favorite of mine, in fact in Champions Online, I have a character that resembles her call Ntoa (named after an African goddess associated with the planet Venus) and Supergirl is hinted at with another character Miss Brainy (the implied daughter of Brainiac 5 and Supergirl). When I'm not playing a gent or robot (and likely the latter), I have the ladies. Well, I'll end my babbling now, lol.
I was never a huge Supergirl fan (or a fan of the Kryptonians in general) because they're just so powerful that it seemed like they really had to go over the top to put them in any kind of remotely challenging situation, but then I played Supergirl for awhile at a role play sim in Second Life and I came to really love the character. She's probably the most enjoyable one I've ever played because she's brash yet unsure, brilliant but often clueless, tough but tender, brave and selfless but prone to fits of rage and self-pity. She's also cute and clever. It makes it a lot of fun to pretend to be her in any situation.
And THAT is the appeal for such a character. Oh, well, for me it was also her romance with Brainiac 5 as I was a huge Legion of Super Heroes fan growing up. Its about the character, what they can do should be secondary to me. If the story has to focus on what they do, its no wonder that so many authors take the easy 'kryptonite-is-a-dime-a-dozen' route. It really should be all that you mentioned. That's the route I took with my book, the robot vessel ferries our heroines about can pretty much do anything, so the story if you will, is how they choose to use 'him' as they command the robot. As Professor Rayna Lashley says at least twice, its not so much can they do something, its about if. If I do it right in the series that should be the dilemma, with the blowing up of stuff to feed the male in me need for explosions. Anyway, yes, that's the appeal for Supergirl, you've put that into words far better than I had in my head.
