Ku'Gath
"'Bubonic' implies something very specific. You cannot just use it for a synonym for 'diseased'-"
- – Ku'Gath splitting hairs moments before Saint Celestine scorches his pus-ridden...everything
Ku'Gath is the single most emo daemonic entity in a universe full of immortals with daddy issues. Once, he was but a Nurgling s(h)itting on Nurgle’s shoulder. Whilst Nurgle was mixing his most virulent disease ever, Ku'Gath promptly did a barrel roll, and tumbled from his place on Papa Nurgle's shoulder into the cauldron, where he took a great draught of the lovely contents and swelled with its power. Invigorated, Ku'Gath drank and drank until the cauldron was empty (the fat shit) and he had grown into a Great Unclean One. Nurgle laughed at the antics of his Nurgling, who had become the embodiment of the perfect disease that had been bubbling within the cauldron. Ku'Gath, however, realised that he had robbed his father of the greatest disease ever concocted (essentially making him emo-Obelix), and has since been wandering the universe, searching for the perfect ingredients to recreate the toxin for Nurgle. He also captures the guys he infects and takes them back to his lair, where he can observe their degeneration more closely.
He met Mortarion when the Primarch came upon him crying, in despair, in the Garden of Nurgle. Upon asking why he was sad, Ku'Gath told him about how he became a Great Unclean One. After they talked for a bit, Ku'Gath told Mortarion where he could find his foster father's soul. They bonded over shared daddy issues and even Mortarion, who hates warpcraft, thinks that Ku'Gath is a pretty cool guy and--in words attributed to him--"relateable."
At some point, Ku'Gath was summoned on the Agri-World of Curwen at the head of the Daemonic Legion. A Grey Knights strike force arrived, and Anval Thawn led a force into the very heart of the Daemonic horde to prevent being surrounded. Ku'Gath swallowed the dude whole, but Thawn detonated his weapon inside the Daemon's throat and burst from its body, and unsurprisingly, Ku'Gath was slain and banished back to the Warp. Ku’Gath appears again in M41, when intervention of Styer and his Grey Knights in the attempts of Inquisitor Malia Orbiana to find biological weapons against Orks (which long story short, the Orks were immune to), which led to the manifestation of the Bonewrack disease, Ku’Gath’s once lost infection, in realspace. The Mary Sues managed to defeat Ku’Gath and his horde of Plaguebearers and expel daemons to the warp, while Ku’Gath himself was wrecked by the blow of Librarian Gared when his Nemesis Greatsword bisected Ku'Gath's head. He later led Nurgle's forces in the Invasion of Ultramar during the Plague Wars. Unfortunately he disobeyed Nurgle's orders during that campaign, causing him to lose his privileged status as Papa Nurgle's favourite son and now he has to hang about for a few millenia to be reincarnated.
Warhammer Fantasy
Ku'Gath is a little bit different in Warhammer Fantasy Battle. First of all, he lacks the daddy issues and has notably less lore. He didn't even have a proper mini. Here, the reason for him to enter the mortal realm is his desire to create new diseases and viruses, and one day create a disease capable of infecting gods. He hates Dwarfs with a burning passion due to their resilience against disease (and a personal defeat at Karaz-a-karak) so he's made a point to use his new blight on them first whenever he finishes it.
In the End Times he assisted the Glottkin's invasion of The Empire, and was eventually banished in Altdorf by Louen Leoncoeur.

Ku'gath is the starting Legendary Lord for the Nurgle faction. A slow BUT TOUGH Lord with access to magic and acts as an artillery!
