No. I mean, yes, technically, but no, because they do kind of have to make it make sense for the character. That's why people are losing their shit because Spiderwoman looks like a sex-superhero rather than a nerdy female photographer that got bit by a radioactive spider. I am not even going into what I am afraid is Venom back there. *shudder* Also, as a personal preference thing, what did they do to her costume? It looks like shit. Triangles? What's the point of those webs, or the gold except to draw focus back to her genitals? Intentionally provocative or not, it's just a bad design. Hell, Deadpool resembles Spiderman more and he was made as a spoof...
In the second set of pictures, you might be able to claim that pose thing if she were a different superhero. One who flies or floats. She looks like she's flying.. If she is a female spiderman then why is she flying? That is not the pose you take if you plan on colliding with a building soon, you would smash your face and worse. That is not a holding-onto-web-and-flying-through-the-air pose either. I mean, seriously? She looks like Storm. Google Storm. That looks like a flying/floaty-power pose, there should be lightning or something in the image for that pose to make sense. She does not have that kind of power if she is a female Spiderman. Alternately, and possibly worse- in light of the of the webbing background, she may be supposed to be laying down. There is literally NO Earthly reason that Spidey would lay down like that, male or female, the character's personality is NOT like that.
Now for the first set... *Exhale* Phhheewwww.... Ok, seriously what in hell, you're really going to try and claim this isn't just blatant fanservice? Spidey is crouched as he is because he needs to maintain hand and foot contact with the surface he's hanging off of- this is kind of part of being Spiderman. The web changes, the suit changes, hell his love interest changes- but this crouch is constant.
But what in hell is Spiderwoman doing over there? Propositioning a passing bird, plane or Superman? She's on top of a building, she isn't crawling over the edge, she's firmly on top- she could stand and instead she's in a position that, honestly, I am wondering if they didn't use a porn shot as reference for. Seriously, "focusing passively"? PASSIVELY, are you kidding? I'm GAY and I'm picking up signals from that one and the only thing passive her position.
Her body is perfect. Her hair is gorgeous and flowing- a female Spiderman should have limp, lifeless hair, probably in a ponytail or a home-haircut, she should be average height, not supermodel height, she should have weight on her body, and small boobs or something. She needs to be visually flawed, shy and awkward and none of these things should stop her from being awesome. The ENTIRE point, and major focus of the Spiderman character's design AND popularity is that he is a gangly (compared to other supers and, average men of the day), socially awkward, not-conventionally-attractive, nerd who uses his experiences with being the underdog in life (as well as the death of his uncle) as the emotional fuel he needs to be brave, fight crime and show that ANYONE can become great and do great things. This is direct rom Stan Lee, it is what he said was his intent when he created Spiderman. If Spiderman got turned from a nerd into a sexpot rather than just getting a sex change then that is sexist as fuck and there's no point trying to deny it.
