No.
Leeloo (Milla Jovovich) from The Fifth Element.
Theora Jones (Amanda Pays) from Max Headroom.
And a third for Lori Petty as Tank Girl. Woof.
Another vote for Aeryn Sun. I’d just about convert for her.
Sara Connor. and not just because she’s got guns and muscles, I’ve always found Linda Hamilton to be a faciinating mixture of toughness and elegance.
C’mell the girlygirl.
–From “The Ballad of Lost C’mell” by Cordwainer Smith
Heinlein’s Friday does it for me, though at a younger stage I was attracted to Jirel of Joiry.
And there’s always Lady Sally of Sally’s Place…
Don’t mess with Ripley! Quiet and capable, not especially beautiful, nobody to be concerned about … until the bad stuff starts to come down.
Though I always kind of liked Tasha Yar from STNG.
Aeryn Sun. Distant second: Mirror-universe Jadzia Dax.
Ivanava from Babylon 5.
Or that green skin chick from TOS.
Molly / Sally from William Gibson’s Neuromancer books. She kicks arse.
No mention of Princess Leia? Honestly, how many guys jacked off for the first time thinking of her in Jedi? (you know the scene)
Clarrissa MacDougal, or “Red”. AKA the “first Lenswoman” and mother of “The Children of the Lens”. Co-inventor of the “wide open two way”!!
What could be hotter than that??
I’m not a fan of the film but Carrie Ann Moss looked pretty good as Trinity in the Matrix.
Lieutenant Ellen Ripley, last survivor of the Nostromo.
It’s got to be Commander Susan Ivanova, from Babylon 5. How many others can have the guts to make a statement like the following?
" I am Susan Ivanova, Commander. Daughter of Andre and Sophie Ivanov. I am the right hand of vengeance and the boot that is going to kick your sorry ass all the way back to Earth, goddammit! I am death incarnate, and the last living thing that you are ever going to see. God sent me. "
Hoshi!!!
(or Dejah Thoris or Princess Leia)
Was there ever anybody to compare with Wally Wood’s Sally Forth?
I think the link is safe, because the details are too small to upset anyone, darn it (although you may have a problem with the ads). But if you look real close you can get an idea.
The original Kochanski from Red Dwarf.
The cute blonde with the cockney accent, not the stuck up brunette from the 7th and 8th series.
Wilma Deering has gotta be up there too. Ardalla was just too sleazy for me.
For sheer eye candy, Xev from Lexx (again, the first one over the second)
I was always preferred Heinleins Hamadryad. If this board’s Hamadryad even comes close to the original, I will begin considering divorcing my current wife and stalking her. 
That should of course be: “I always preferred…”. I guess the champagne from my company’s New Year’s lunch is getting to me.
I could be mistaken, but wasn’t that Yvonne Craig (Batgirl)?
