Godzilla from Warhammer 40K

Guilliman was fighting on the front line at this time. Like Mortarion, his front line broke into the Death Guard's position with great momentum. Even the Ultramarines' glorious champions could not keep up with him.

However, there was also a Nurgle front line breaking into the Ultramarines' position. The two Primarchs seemed to have reached a consensus at this moment and met in a square.

Guilliman pulled out the Emperor's Sword that was inserted into the Death Guard warrior, and Mortarion had just finished his slashing of a Dreadnought.

The two men's eyes met.

"My brother."

Guilliman's face was extremely calm, but his heart was already filled with anger.

"Ah, Robert Guilliman, you are still the same as you were ten thousand years ago."

"And you, my brother, the stench on you makes me sick! Even if I am dozens of kilometers away, I can smell the stench on you!"

"As a loyal dog of the false emperor, your sense of smell is very sensitive."

Although Mortarion did not want to rebel ten thousand years ago, he has seen too much corruption and decline of the empire in the past ten thousand years. Now he is a determined Chaos Demon Prince against the empire.

"Stop talking nonsense. Today, I will not let you run away again."

Guilliman did not even want to talk nonsense with his brother, so he rushed towards Mortarion.

The battle between the primarchs was extremely fierce. Mortarion could make up for the disadvantage in speed by relying on the size of the demon prince and the regeneration ability of Nurgle.

"What a pity, you and your Ultramarines Legion were not there on Isstvan V, otherwise, you might not be able to stay here alive."

Istvan V, a place that Warhammer players are familiar with, was where a melee between nearly ten legions and the Primarchs took place, and the loyalists were ambushed by the traitors and suffered heavy losses.

Even the Primarchs were killed and captured.

"You dare to mention Isstvan V? Ferrus' revenge will be avenged by me!!!"

Guilliman had a good relationship with Ferrus, the Primarch of the Iron Hands Legion. When he thought of his taciturn but serious brother who died tragically at the hands of a traitor, Guilliman was extremely angry.

This anger even overwhelmed his reason.

The flames of the Emperor's Sword became more and more violent, and Kal'tsit, the girl who hosted the Emperor's power, also came to the battlefield in person.

She exudes the glory of the Emperor, but no one has noticed it yet. Her divine eyes quietly watch the battle between Guilliman and Mortarion, and no one knows what she is thinking.

Mortarion, the son who once experimented on human beings and cherished life, has now become the character that Mortarion hates the most.

Guilliman began to gradually suppress Mortarion. After all, the power of Nurgle in Mortarion's body declined too much, causing his body to begin to feel uncoordinated. He could not fly and could only fight Guilliman on the ground.

Mortarion felt bad. If he continued to fight like this, he would most likely lose.

But Mortarion was well prepared. In the confrontation with Guilliman, he deliberately exposed his flaws and took a solid blow from the Emperor's Sword in Guilliman's hand.

The sword slashed on Mortarion's shoulder, almost cutting him in half, but Mortarion threw away the Plague Scythe, grabbed the hilt of the Emperor's Sword with one hand, and took out the potion prepared by Nurgle himself with the other hand.

He firmly inserted the potion into Guilliman's neck.

"It's over, brother."

Mortarion's low laughter came from his respirator.

"You are still the same as before, you don't remember."

Guilliman took a few steps back, and the plague almost instantly caused his demigod-like body to suffer fatal damage. It was not just a virus or bacteria, but also the power of the warp.     Don't think it's outrageous, because the setting of the Smurfs has always been not to accept their own warp nature, so the magic resistance is 0 or even negative.

Last time, he was also knocked unconscious by Fulgrim's sword, and he really didn't remember.

Guilliman was holding on completely by willpower, but he couldn't hold on. He knelt on the ground with his sword, his consciousness becoming increasingly blurred.

"You, you."

"Embrace the arms of a loving father, brother."

But this time, Mortarion made a mistake.

He had the help of his loving father, how could the Emperor watch his eldest son die.

Behind Kal'tsit, a divine aura belonging to the Emperor emerged. She stretched out her hand, and a golden light also emerged on Guilliman's body. Mortarion's eyes widened.

"This power can't be wrong, it's you, why are you here?!"

Guilliman stood up again, but this time Guilliman's eyes were particularly cold, and Mortarion had only seen that kind of look on one person.

"Father."

The Emperor would not make the same mistake twice. Last time, Fulgrim put Guilliman into a coma. The Emperor was not a god and could not save his child.

This time.

Daddy is going to spank the child.

‘Guilliman’ raised the Emperor’s Sword high up, and the light it shone from was as dazzling as a second sun. This sword had destroyed countless demons in the Webway War.

“Wait, wait!”

Mortarion was really panicking this time, because the Emperor’s Sword was a weapon that could really destroy demons.

But how could ‘Guilliman’ stop? He swung the Emperor’s Sword heavily, and everything related to Nurgle in the square was enveloped by the Emperor’s wrath, including Mortarion.

“Ah——————!!!”

The Emperor mercilessly executed the beheading. Mortarion's body burned in the Emperor's flames. Nurgle's power allowed him to resist for a little longer, but the ending was doomed.

Mortarion died. He became another Primarch killed by the Emperor himself, and the fourth Primarch killed by the Emperor himself. The other three were the two disappeared Primarchs and Horus.

This was indeed a rare opportunity. Usually, with Nurgle's power protecting him, the Emperor had no chance to kill Mortarion.

This time, Nurgle was really in trouble. Until Mortarion was completely destroyed, he was unable to spare his strength to save Mortarion, and even a Great Unclean One did not appear.

"That's it, Mortarion."

Kal'tsit murmured, "Take your leave at this moment."

The Emperor had no attachment to Mortarion. Perhaps he had a little guilt as a father, but that guilt was not enough to make him show mercy to Mortarion.

After Mortarion's death, the Death Guard could feel the grief of the Primarch's death. They launched a final resistance against the Ultramarines, but it was meaningless. This madness was not enough to make up for the disadvantage in the battle.

The outcome of this battle was already determined, just like the battle on Isstvan V, but the outcomes of both sides were reversed.
