Turbinid-Dragon

The Turbinid-Dragon (リュウサザイ) is a creature that lives in the 6th Layer of The Abyss, where return is humanly impossible.

Description
First documented in the notes of the White Whistle Delver Lyza "The Annihilator", Turbinid-Dragons resemble a dinosaur-sized horse with a long neck and a beak-like mouth, which sports six large fang-like tusks on the lower jaw.

They have poisonous scales like reptiles, that act like a carapace and their old scales rupture when struck and release the strong poison inside them. They have six long legs to support their body. The end of their back holds a growth reminiscent of a snail shell with multiple appendages that sometimes move around seemingly unrelated to its bodily movements.

Turbinid-Dragons are tenacious and move freely in three dimensions without any regard to the curse. The males often fight each other, over territory, by aggressively slamming into each other. They are immensely strong and their towering, huge size makes them imposing figures. A single Turbinid-Dragon is as dangerous as an entire swarm of Amaranthine-Deceptors.

They are territorial and don't appear to be particularly aggressive, as long as that territory isn't breached.

The Turbinid-Dragon, like the Silkfang, Inbyo, and Orb Piercer, will hunt and attack any intruder entering its territory. Once close enough, it stomps and impales its prey with long, rigid legs that were even able to chip the strong metal of Reg's arm. They also have a great sense of intuition, that almost resembles premonition, making it easy for them to accurately attack even targets much smaller than them.

When further from its prey, its proboscis-like appendage opens and spits a slimy projectile consisting of a mixture of stony material from its organs and a secreted liquid. This liquid explodes on impact, with the heat waves set off from the metal and stone projectiles and liquid causing major damage to the surroundings. It also uses it as intimidation tactic against enemies.

Trivia

 * One of the beasts of The Abyss that can damage Reg's body.
 * A Turbinid-Dragon severely damaged Gaburoon, in the past.
 * According to Faputa, a Turbinid-Dragon changes its territory randomly. She also claims to have seen its excrement burning before.
 * Turbinid-Dragons have a seemingly indefatigable ability to attack, even as its internal organs are injured and are believed to be immortal.
 * Though not an ideal way to deal with it, dropping it from a considerable height may greatly injure it, but one should avoid engaging with this creature directly at any cost.
 * Its talons can instantly harden to extreme rigidity when force is applied. Though there are Artifacts with this property, it is unclear whether they are related.
 * According to Riko, there are some species where the males place their offspring into their bodies and raise them in it. Nanachi theorizes whether or not the appendages on the rear may belong to the respective offspring.
 * According to a tweet by Tsukushi, the Turbinid-Dragon possesses multiple brains around the neck, meaning they don't seem to mind receiving injuries on multiple of these.
 * The Japanese name "Ryuusazai" is derived from the words "リュウ" (dragon) and "サザイ" (sazai). "Sazai" or "Sazae" being a reference to a type of spiral-shelled snail.
 * The Turbinid-Dragon's English name is likely derived from the Latin root word "turbinis", which means "spiral", reflecting the spiral patterns on their bodies.
 * The Turbinid-Dragon's poisonous, explosive scales are said to stop working, once it dies.
