Rauchitas

The Rauchitas was a three-headed Tier 1 Dragon, known as the dragon king of poison and curses. It was a fearsome monster that was extremely difficult to kill. After its freak appearance in a D-rank dungeon, where it killed Han Yoohyun, it was in turn killed by Han Yoojin.

Appearance
The Rauchitas had red scales covering its massive, sleek, leopard-like body. It had three heads with sawtooth-like teeth, four legs with large claws, and no wings. Poisonous fumes flowed off its body, able to kill those who got too close. It also had ridges along its back that it could raise when agitated, and a long spotted tail lined with spines. Each of its heads had two eyes with slit pupils.

Personality
As a dungeon monster, the Rauchitas was an incredibly hostile and dangerous creature set on killing any humans around itself. It was stubborn, chasing after Yoojin even when he flew up and out of its reach, but was quickly cowed when faced with an opponent far stronger than itself.

History
The Rauchitas was created and raised by Diarma from a magic stone embedded inside his body, as with many other poison/curse dragons, including some of the same species.

On two occasions, a Rauchitas appeared inside Earth's dungeons, and endured the raiding party's attacks until the dungeon gates closed. It's unclear if this was the same individual as the one that appeared later and killed Han Yoohyun, or if they were separate dragons.

Synopsis
In order to convince Han Yoohyun that he needed to collaborate with the filial duty addicts, the transcendent Diarma purposely sent the Rauchitas into a D-rank dungeon that Han Yoojin had entered, intending for Yoojin to die and convince Yoohyun that he needed to be stronger. The Rauchitas killed the raiding party that Yoojin had entered the dungeon with, and moved its attention to Yoojin himself; however, as part of his deal with Diarma, Yoohyun was able to enter the dungeon and fight off the Rauchitas, burning out its middle head's eyes. However, the Rauchitas' attention eventually strayed back to Yoojin, and it attacked him, only to land its killing blow on Yoohyun, who'd defended his brother. Last Compensation activated and gave Yoojin SS-rank abilities, which he used to slowly and methodically cut down the Rauchitas, killing it.
