Update for a description of the final monstrosity.
[spoiler]Flying above you, over ten feet tall, the monstrosity, barely humanoid in shape, roars; its muscles swelling to almost comicly large proportions. It's form is covered by hard chitin of a deep blue color, with layers of flexible, crimson scales under the joints and cracks. Oozing pustules and unblinking, multi-faceted eyes cover the chitinous shell. It's shoulders and arms appear to be from some other creature entirely, stitched and riveted into place. Halfway down, the arms transform into tentacles, though they still end in clawed hands. Ten more tentacles and five more arms sprout from each of it's side, and from it's chest, eight pairs of tentacles squirm hungrily. Each tentacle ends in a wicked, clawed hand. Thirteen long, flexible necks sprout from it's shoulders, each supporting it's own head. It's mouths are toothy maws, each surrounded by four writhing tentacles, also ending in clawed hands, and a pair of mandibles. It's eyes are multi-faceted, like that of a giant fly, and a large crest of spines, accented by a pair of twitching antennae and a pair of massive horns, starts at each snout and travels to each spine. A tangled mass of scraggly hair adorns each head, with a small, twisted knife braided into the matt. From it's back spread a large pair of bright ruby wings, scaled and covered in spines. It's segmented torso is elongated, stretching out over fifteen feet, and coiled beneath it as it flies. A hundred pairs of small, insectile legs sprout from underneath it. Each leg splits into a mass of 10 twisted tentacles topped with a small, gnarled hand. The end of the torso sports a long, snakelike tail. It's armor is stitched and welded together from smaller suits, and is adorned with many spikes and blades. Each of it's hands carries two blades shaped like the crescent moon, and it's mouthes use it's wicked teeth to wield two more. Wrapped in the end of it's tail are two more. Each of the crescent shaped blades is also on fire.
When it attacks, it throws the knives in a kaleidoscopic whirlwind of motion. Each knife somehow finds it's way back to the creature to be thrown again and again, leaving an insane network of trailers from the flames that adorn them. Occasionally one of the knives bursts into fire when it finds it's mark, yet the flames still trail back to the creature, reforming the blade to be thrown again. At the same time, it's snakelike heads lash at, battering it's foe with it's necks, horns, and the blades twisted in it's hair. It's torso also swings around, dragging the spiked and bladed armor across it's enemies.[/spoiler]
