Everyone in that poster is in the middle of something. They're busy. They don't have time to care about anything other than trying not to get killed. All but one, that is: Scarlet Witch, who's played by Elizabeth Olsen. Of all the Avengers, she's the only one who noticed that someone set up a canvas and decided to capture this terrifying, unspeakably bonkers moment in human history by painting it. Scarlet Witch couldn't help but notice that an unseen spectator wanted to capture her fierce battle essence, so she struck a sassy pose for the artist as she obliterated a robot's head:

The Hulk's there trying to rip robots off his body, and Captain America is trying to bulldoze his way through a murderous metallic sea -- Scarlet Witch, meanwhile, thinks she's the center of a flash mob. She's bustin' moves and projecting her inner Sasha Fierce. Splatting that robot's head into red mist is just a repercussion of her passionate choreographed dance. And I know she's dancing because she's in the middle of performing the exact move the Backstreet Boys do in the video for "Everybody."

She's an opportunist. Humanity is about to be killed off by a sentient robot and his legion of robot soldiers -- might as well get a modeling contract out of it. And if working it doesn't land her a career worthy of a Kardashian, she'll use her insane power to alter reality as she sees fit to get herself some of the precious mana of fame she richly desires. Work it, girl; get that cover of Cosmo.

There's a lot of silly, fantastical comic book bullshit going on in that poster: a giant monster-man fighting robots, a man dressed as a robot fighting legit robots, two squishy humans with no superpowers who aren't getting ripped apart the way ground beef would if it were thrown at a jet turbine -- lots of suspended disbelief is needed to buy into the world and start having fun. But somehow one very normal thing is the most unrealistic part of the entire poster:

Out of context, I would think that's a picture of a misshapen peanut wearing a glove. In context, it's Thor's right arm. I know he's a god, and I know he's a comic book character, but I don't have arm blindness. I have before and will continue to see what Chris Hemsworth's arms actually look like. The guy's got godly arms because he can suck the protein out of an egg through its shell, and he tucks a horse's pituitary gland in his armpit when he works out so he can absorb horse strength. None of that can make an arm look like a woman who's pregnant on both sides.

His biceps isn't all that crazy. It's his triceps that makes me think Jiffy Pop popcorn is going to spring out through a tear in his skin with a burst of buttery steam. But notice how his left arm isn't nearly as intense:

Conclusion: Thor wields Mjolnir with the left and masturbates with his right. Puzzled solved. Moving on ...

Like I said earlier, the poster is like a Where's Waldo? book with small stories taking place in every nook and cranny. Zoom in to a random spot and you'll find something interesting. So, there I was, zooming in on Scarlett Johansson's cleavage, when I scrolled to the left and saw one of the robots revealing a side of itself that can't be seen on any other robot in the picture:

Mm. Firm.

Looks like these things have buttholes -- big ones, too. Prolapsed human buttholes that have been bronzed like baby shoes. I know, I know -- it's not actually a butthole, just a little design touch added to make the robot taint more visually appealing for the 1/8 of a blurry second you'll probably see it on screen. See, in the age of pause buttons and 4K resolution, every inch of everything has to be packed with detail or else fans will take to the Internet and claim laziness on the part of the designers. If the robot's taint were smooth and devoid of all trace of a pooper instead of looking like a cannonball squeezing through a pinhole in a sheet of aluminum, fans would feel like it was a missed opportunity. Better to have the robots in a constant state of crowning as they give birth to a parking meter than have nothing going on between the legs.

It's better to have a vampire bat for an asshole than no asshole at all.

The metallic genitals don't end there: These robots have vagina spines! I don't mean barbed vaginas -- that would be unseemly. I mean their spines are shaped like flappy vagina wings.

Marvel/Disney

I know what you're thinking: Of all things, how do I know for certain that their spines look like modern art vagina sculptures made of recycled soda cans? Well, because I once wrote an article for another site wherein, for journalistic reasons, I had to closely examine a Fleshlight that was made to look like a cyborg's pussy. I'm not going to post the picture here, but I sure will link to it.

Back puss.

Look at that "cyborg" labia and look at the spine on Ultron's robots -- tell me those things don't look like cousins from the same family of design ideas.
