Maxwell as Cairax, alive

On a guess it was maybe nine or ten feet tall, but it was tough to be sure because it was hunched over. It was more or less human-shaped, but the proportions were off. It was too tall and thin, like a person who’d been stretched out on a rack and stayed that way. It made every step and swing of its arms seem unnatural. It had a tail that looked like a cross between a dinosaur and a scorpion.
Its head looked like a fish. One of those deep-sea fish with the huge eyes and teeth so long it could barely close its mouth. Half a dozen stubby horns circled its scalp like a weird crown or something.
It had the third kid by the ankles, hanging him upside down so the boy’s eyes and its were level. Its tongue was out, this long thing like a snake. It was poking the kid on the nose. The kid was bawling, almost drowning in his own snot. There was a glossy stain on his jeans and it was creeping into his shirt as it followed gravity.
