As the Orks land, they immediately clash with the Death Guard forces around Hive Tertius. The once-quiet, disease-ridden streets erupt into a chaotic melee, with Boyz swarming over Plague Marines and Red's new Ultra Deff Dreads smashing through the corrupted defenses. These new Dreads still have Orks wired onto them, and they still have a very Orky look, but they are far more advanced and now carry weapons that are twice as powerful while being far less likely to blow up, which takes some of the fun out of it, but makes them terrifyingly effective.
Killkrumpa unleashes devastating psychic attacks, channeling Waaagh Warp Energy to blast apart squads of Poxwalkers and even bring down the towering Plagueburst Crawlers. His abilities are amplified to unbelievable heights by the daemon batteries. With the Weirdboyz and Big Shootas of First Mobz at his side, some of them getting vaporized along with the Plague Gits, but every one of them laughing and roaring at their Boss's side, they drive a speartip assault worthy of the fallen Luna Wolves into the heart of the Death Guard.
Red, always looking to help her Boyz, begins to take control of the planetary data networks, using corrupted systems to create chaos within the Death Guard ranks. Corrupted Autocannons and las-turrets, now under Ork control, turn on their former masters, providing covering fire for the advancing WAAAGH! She also deploys inside her newly captured and modified T'au Battlesuit, which the Boyz call Red Dreads, both because she controls them and they are all red because, as everyone knows, red ones go faster. Squadrons of new Ork Supafliers, also red, deploy as well. These new Ork Supa Dakkajets move fast, are more maneuverable, and have an array of weapons the Ork Aces waste no time in firing. What makes these Ork craft infinitely more lethal, however, is the fact that all their pilots have had their minds altered by Red, making them less likely to fire a missile because they want to see it go boom and more likely to fire it into key enemy positions and at aerial opponents after AIMING! Or at least after letting the slave machine spirits aim for them. Same difference. The air of over Hive Tertius soon belongs to the Orks.
Typhus, still furious over the loss of the Terminus Est and realizing the threat posed by this unanticipated Ork invasion, leads a counterattack against the Orks himself. His presence on the battlefield is a chilling sight as he strides through the chaos, spreading death and decay with every step. He unleashes one of Nurgle's greatest gifts, the Destroyer Hive, sending swarms of Warp flies carrying the Destroyer Plague which rots everything not protected by the Grandfather. Many Mobz who ranged ahead are turned into little more than sludge as the most powerful of Nurgle's plagues rot runed armor and flesh alike. Deff Dreads are corroded to dust the Orks inside rotted to slim and blackened bone. As Typhus advances with the most powerful of his tainted brothers at his side, this looks to be a turning point. Until…
"Hey, Plague Git," says Killkrumpa as a Warp Portal opens beside the Death Guard advance, "Catch!"
An entire Baneblade flies out of the portal, and Typhus barely has time to channel his power into rotting it to rust before it hits. It explodes into rust dust, but the real threat is right behind it. Killkrumpa, coming from a second portal above the first, lands in the midst of the Death Guard, his shootas blazing as his massive claws and tail flash out in every direction. The ancient corrupted Terminator Plate and Nurgle-gifted resistance of Typhus's First Company's rotting bodies do nothing to protect them as claws, and Waaagh Warp rounds cut them to pieces and blast them apart. Warriors who fought during the Siege of Terror and who have terrorized the galaxy for ten thousand years are cut down in moments as Killkrumpa shows them the real meaning of a krumpin'! Typhus, who just managed to roll away, watches as the avatar of violence slaughters his brothers to a man. After Killkrumpa crushes what is left of First Sergeant Deucaleo under a massive metal boot like an insect, he turns his burning gaze on the Typhus.
"Typho Da Travla I take it," says Killkrumpa, in Low Gothic "Now why did you go and melt my Boyz like that? Don't you know that I am the only one who can melt my Boyz like that? Now, I am going to have to stomp ya flat. I mean, I was going to do that anyway, but now, imma do it twice as hard."
Typhus roars in rage and unleashes the full force of the Destroyer Hive on the towering Killkrumpa. The Daemon Flies all swarm over the Ork in a black cloud. So much Destroyer Plague is unleashed that reality starts to rot where the flies swarm. Killkrumpa is rotted down to whatever passes for his soul. Or so Typhus thinks right up until booming laughter rings from the center of the swarm.
The laughter gets louder as a green light starts to emerge from the black mass of the swarm. The green flames grow into a towering blaze that fills the air with the smell of burning rotted meat. The Daemon Flies are burned from reality until Killkrumpa stands in the ashes, still laughing, untouched by the Destroyer Plague. Typhus takes a step back as an emotion that he thought he had stripped from him ten thousand years ago rocks him: FEAR!
"Ya ain't fightin' no wimpy puny here, Typho," roars Killkrumpa as he laughs, "Ya are fightin' the Biggest Boss of the Waaagh Eternal. Ya are fightin' the Avata of Gork and Mork. Ya are fighting Red's Chosen Boy. Ya are fightin' the BEST THERE IS! AND THE BEST THERE EVER WILL BE! YOU ARE FIGHTIN' KILLKRUMPA WEIRDBLITZ!"
The flames around Killkrumpa blaze like a mini supernova now, and he aims all four of his arm shootas at the puny and opens fire. Typhus the Traveler, Chosen of Nurgle and scourge of the galaxy for over ten millennia. The reason for the Death Guard's turn into the playthings of the Plague Father is blown to so many tiny pieces that even Nurgle himself couldn't find them all. His burning soul is sent howling into retreat back into the Plague Garden, where it sets fire to it. That fire will never go out, no matter what the Plague Father tries. Typhus's screams of agony rage in the center of the Waaagh Warp flames as he is unable to escape from it and unable to die because of Nurgle's blessings. The Burning Field is now a permanent part of Nurgle's Garden, and so are the screams of the Grandfather's favorite son.
Killkrumpa doesn't know or care about this as he strides back into battle. His mind had already moved on to the next fight. There are still plenty of Plague Git and zombies to stomp.
