The thing is, when Skizz looks in a mirror, he looks the same. But to everyone else, it’s never the same. He knows that he looks different to everyone, so he just takes advantage of that and gaslights everyone
So I draw Impulse and Skizz as a Demon and Angel. And I thought, what if I made them more demonis and angelic? This is my head cannon of their true forms. (I made them monochrome cause I’m lazy lol)
For Skizz, I imagine that he follows the “biblically accurate” Angel design. Lots of wings and eyes, but I also imagine that his form is constantly changing. Since an Angel’s appearance is supposedly too much for the human mind to understand, Skizz’s form always looks different every time he changes to it. But his wings can vary in size and are very soft. His Halo becomes very ornate as well. I imagine his blood turns gold in color which reflects on his scars and his eyes are glowing blue. Like his entire eye, no pupils or iris, just blue sclera
For Impulse, his whole body becomes incased in his black scales(do demons have scales?). His horns grow much bigger, along with his tail, and his wings. The ends of his horns, tail, and wings bleed yellow. His hands and feet turn to claws, also his feet grow too big for his shoes lol. He also has a few spines protruding from his back. His teeth become razor sharp and his tongue is forked and..really weird. His eyes turn to golden sclera and black slits for pupils
I like to think that Impulse is very self-conscious about his true form, which is why he hides almost all of it behind his glamour. Skizz isn’t, but in solidarity with Impulse, he also covers it. Only a few of the Hermits have seen fully Demonic Impulse. Obviously Xisuma for admin reasons, but only Tango, Mumbo, Zed, Grian, Gem, Pearl, and Bdubs have seen Impulse’s true form. But half of the server has seen Skizz’s, or at least a version of it.
