The Threat of the Rognarrs was a calamitous chapter of Viltrumite history on the high-gravity Savage Planet, where the empire, still weakened by plague, lost warriors to the ferocious Rognarrs before freezing the creatures and their world solid.
The Threat of the Rognarrs stands as a disastrous episode from the distant past of Viltrumite history, unfolding on the world known as the Savage Planet. During a scouting mission there, a Viltrum Empire still reeling from the Scourge Virus ran up against the deadly Rognarr creatures, and the encounter left several of the surviving, virus-stricken warriors dead or gravely maimed. The planet's crushing gravity proved as much an enemy as the beasts themselves.
The first incident came in the wake of the Scourge Virus, when Nolan and his partner were dispatched to survey the harsh Savage Planet for the empire. Its gravity ran crushingly heavy, the pull so fierce that the two could barely move, and after turning up no usable resources they prepared to head home. Without warning the Rognarrs struck, killing Nolan's partner and swiftly pinning Nolan down. The creatures could tear flesh from bone, hold him fast, and spring enormous distances to snatch him from the air whenever he tried to flee, and how he ultimately survived and got off the planet remains unknown.
A second incident followed in later years as agent after agent failed to capture or kill even one Rognarr. Among them, a weakened Conquest ventured to the Savage Planet and fell victim to the beasts, his body so badly wrecked that he came away with a blinded, scarred right eye and a mechanical arm replacing the limb he lost. Recognizing the danger the creatures posed, the Viltrumites at last placed an enormous solar disc before the sun, freezing both the star and the Rognarrs entirely.
Nolan and Conquest are the recorded survivors of the ordeal. Nolan's unnamed partner was killed by the Rognarrs early in the first mission. General Kregg is named among the Viltrumite command tied to the campaign, and the Rognarrs themselves stood as the opposing force before being sealed in ice along with their planet.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Yes, the Threat of the Rognarrs is a real, disastrous chapter of Viltrumite history, in which ferocious creatures called Rognarrs killed and maimed several Viltrumite warriors on the high-gravity Savage Planet. The Empire eventually ended the danger by freezing the Rognarrs and their entire planet solid with a massive solar disc.
The Rognarrs were dangerous enough that repeated Viltrumite agents failed to capture or kill even one, and encounters left warriors dead or gravely injured, including Conquest, who lost an eye and an arm. Recognizing the danger, the Viltrumites ultimately froze the Rognarrs and their planet solid rather than keep fighting them.
The Threat of the Rognarrs took place on the Savage Planet, where a Viltrum Empire still weakened by the Scourge Virus encountered the deadly Rognarr creatures during a scouting mission. Nolan's partner was killed and Nolan himself nearly died in the first incident, and a later attempt by Conquest ended with him losing an eye and an arm before the Viltrumites froze the planet to end the threat.
The Threat of the Rognarrs occurred on the Savage Planet, a world with crushing gravity so heavy that Viltrumites could barely move. It was there that the Rognarr creatures killed Nolan's partner and maimed Conquest before the Empire froze the planet solid.
Nolan and Conquest are the two recorded survivors of the Threat of the Rognarrs. Nolan's partner was killed in the first incident, and Conquest was left with a blinded right eye and a mechanical arm after his own encounter with the creatures.
