• Marneus Calgar (Space Marines) – representing the Ultramarines. Calgar is one of the Imperium's most iconic Chapter Masters and appears to be the flagship Space Marine commander.
• Commissar Sebastian Yarrick (Astra Militarum) – the legendary "Hero of Hades Hive." His rivalry with Ghazghkull makes him a natural centerpiece for an Armageddon-focused campaign.
• Ghazghkull Mag Uruk Thraka (Orks) – the greatest living Ork warboss and the obvious face of the Ork faction. His presence was strongly teased alongside Yarrick and has been confirmed.
• Nazdreg Ug Urdgrub (Orks) – revealed today, adding a second named Ork character to the roster and bringing the Bad Moons into the spotlight.

*RUMOURS ONLY*

• Roboute Guilliman (Space Marines): Primach from the Ultramarines and Lord Commander of the Imperium. The rumor stems from a Funko POP! product listing that includes Roboute Guilliman with branding tied to Total War: Warhammer 40,000. The product description reportedly reads: "Rally your armies! POP! Roboute Guilliman is here to join the cause in your Total War: WARHAMMER 40,000™ collection."

I saw a lot of people comparing the two veterans warriors, thirsty for new opponents to fight, and many keep asking, who would in a fight? Well,

I made a research and I wrote how a battle between the two of them would go:

The sky above the ruined city burned orange.

Smoke drifted between shattered skyscrapers as civilians fled through the streets below. Craters scarred the earth of the alien planet like meteor impacts.

Hovering calmly above it all was Nappa, arms crossed, grinning with the confidence of a man who had erased civilizations before breakfast.

Then the air changed.

A sonic boom ripped through the clouds. Something slammed into Nappa from behind hard enough to launch him through three buildings, with concrete exploded outward, and Nappa skidded across the ground, trenching through asphalt before stopping, with dust settled around him.

Standing in the middle of the destruction was Conquest. The blood of the saiyan stained the Viltrumite’s white uniform, and Conquest’s single eye gleamed with excitement. “Finally,” Conquest growled, cracking his neck. “Something that might actually fight back.”

Nappa slowly stood up, then he laughed. A deep, mocking laugh. “Oh, I like you already” he said it.

The ground beneath Nappa shattered as his aura erupted outward in a storm of yellow energy, with cars flipped into the air, and windows detonated for miles, which only made Conquest smile wider.

As they trade blows with one another at high, it was almost like for common viewer that they vanished. A shockwave exploded across the city as the two collided midair, making all the poor aliens caught in the middle of their duel being obliterated without neither of the warriors noticing or caring how many innocent lives are caught in their destruction.

Conquest drove a fist into Nappa’s jaw hard enough to bend a skyscraper behind him, though Nappa barely moved. He answered with a brutal elbow that sent Conquest hurtling into the horizon like artillery fire, and right before Conquest could recover, Nappa appeared above him instantly, being too fast for the Viltrumite to keep up, proceeding Nappa hammering his opponent downward.

The impact split the city blocks beneath them apart, devastating the city. However, Conquest emerged from the crater with ease, laughing through broken teeth. “That’s more like it!”

Conquest lunged again against the saiyan with savage precision, attacking relentlessly, with punches, elbows, grapples. Unlike Nappa, every movement from Conquest was efficient. Cruel. Experienced. And for a moment, it was working.

Conquest locked onto Nappa’s arm, twisted, and drove him through a mountain range outside the city, with entire cliffs collapsing around them, ending with Conquest throwing him against the wall of a mountain.

Nappa stood up once more, snarling, becoming increasingly irritated instead of amused. Conquest was about to charge again against him—

—and suddenly he froze. For the first time, he sensed it, something truly dangerous going on.

The energy Nappa was gathering in his palm. A concentration of ki was increasing exponentially like a volcano about to erupt, making the entire area around them, no, the entire world they were on, to start shaking violently.

Conquest’s smile faded slightly. “Oh.”

Nappa grinned viciously. “Now die.”

Nappa raised his palm up and a bright light engulfed them.

Nappa caused an explosion that consumed one third of the planet. Mountains vaporized instantly. Forests ignited. The atmosphere itself seemed to split apart as the explosion swallowed everything for dozens of kilometers. For several seconds, there was only light.

Then silence.

Smoke rolled across a burning wasteland, with Nappa standing over the land he destroyed. While the smoke cleared, a figure started emerging near him.

Conquest.

Half his body was charred black, his mechanical arm destroyed, and blood poured down his face. But he was still alive. And still smiling.

“That…” he wheezed, “…was incredible.”

Nappa’s eyes narrowed, most opponents died immediately after that attack. But there was no time to be annoyed, Conquest launched himself forward immediately, one final time with suicidal fury, smashing into Nappa and driving both of them across the ruined landscape.

The Viltrumite clawed, punched, bit, fighting like a cornered animal, not showing any sign of stand down. For a brief instant, Nappa actually struggled, this guy was clearly a veteran of a thousand battles. But then the Saiyan’s expression hardened.

Enough.

Nappa grabbed Conquest by the throat, lifting him effortlessly. The viltrumite desperately tried to pierce the saiyan’s body, but his skin was to hard to pierce through. And despite Conquest best attempts to try killing his enemy first, Nappa fired a point-blank energy wave directly into his chest. The beam tore through Conquest and continued into the sky beyond, splitting clouds across the horizon.

Conquest’s body went limp, and Nappa tossed the corpse aside. The Saiyan looked over the burning wasteland with disappointment.

“Hmph. Tough guy.” Then he smirked. “But not tough enough.”

Nappa went to his space pod and returned back to Vegeta. He couldn’t wait to talk all about the guy he fought here today. That is, not before making fun of Raditz alongside Vegeta.

WINNER: Nappa
