ok so i was looking at this picture and i realized something
karkat in this always struck me as weirdly animated, he doesn’t look like he is sitting down, actually he looks like is just floating and got put on a background
but upon comparing him to the other two while tracing an imaginary line as to where their butts should be, i noticed where the problem was.
you know how when you sit, your bum gets a bit flattened because it’s a cushioned surface being pressed with the weight of your body?
like this? compare it to
sakamoto’s little butt stays perfectly round because he has no chair.
but now let’s look at karkat again, if he isn’t sitting then what is he doing?
in case the perspective is a bit harsh on you let me elaborate
those lines indicate the balance of karkat’s body, with the point receiving most force in the middle which in this case his bum, holding the weight of his torso and half of his legs. that’s the gravitational pull
but through perspective, you can see that his bum is under the same line than his left foot, in other words, his butt has to be higher than his hands and feet because the left foot line (in light blue) doesn’t match.
Karkat is not sitting down guys HE IS DOING THE CRAB!
so there you have it guys, the physics of karkat’s ass
