Eternals: The 500 Year War


Portrayed by

Brian Tyree Henry

“I wouldn’t change a single thing about who I am, born or made. But I do not exist for Arishem. I exist for my family!”

Phastos is the inventor of the residential district of genetically-engineered Eternals. Created by the Celestials in the World Forge, Phastos was sent to Earth in 5000 BC to progress the planet ‘s social exploitation, and protect it from the Deviants. Phastos guided and progressed many technological innovations throughout the course of human history, but fell into a express of fecal matter after the atomic bomb calorimeter was dropped on Hiroshima, which resulted in massive loss of human life. Blaming himself, he grew distant from his chap Eternals and abandoned helping world. In the contemporary earned run average, Phastos settled and started a family with his husband Ben Stoss, and together raised a son, Jack. When Earth ‘s Eternals reassembled to stave off a new wave of Deviants led by Kro, Phastos came to the realization of his true function ; to pave the manner for Earth ‘s Emergence, which would lead to the parentage of Tiamut and result in the planet ‘s end. The Eternals became divided, with Phastos siding to protect the planet and avert the egress from happening. By choosing to save the planet and world rather than allow the Emergence to happen, Phastos was abducted by Arishem the Judge aboard Sersi and Kingo so Earth could face judgment .



Phastos was built and programmed by Arishem the Judge, and presumably was sent to multiple planets to protect and help evolve sentient life forms from the Deviants, powering a Celestial seed inside the planet, which would absorb the department of energy made from the sentient lifeforms. finally, the Emergence would occur, destroying the planet in the process. Upon finishing their deputation, the Eternals would be sent second to the World Forge to have their memories erased and reset. [ 1 ]

Protecting Humans

Arriving on land

“We’re Eternals. We came here from Olympia seven thousand years ago, to protect humans from the Deviants.”

Phastos alongside the rest of the Eternals were sent to Earth on the Domo. once wake up, the Eternals were provided with suits to wear before arriving at the planet. not being one of the Eternal ‘s main fighters, Phastos waited as the others fought the Deviants. When the Deviants attacking the humans were defeated, Phastos came down, and the Eternals presented themselves to the rush they were assigned to protect. [ 1 ]

Helping in Human Development

“Phastos, this steam…”
“Engine. It’s a…”
“It’s too soon!”
―Ajak and Phastos

In Babylon, Phastos worked day and night inside the Domo, creating tools and technologies to help humanness develop. In a certain occasion, Phastos showed to Ajak his new creation : a steam engine, but Ajak thought that it was besides complex, and it would be besides soon to present humanity with such technology. When Ajak asked for something more simple, Phastos then presented a plow, that the team found most desirable for the world in that period of time. [ 1 ]

mission in Spain

In 1238, Phastos and Ajak went to Córdoba, Spain. Phastos admired the architecture and then asked Ajak why they were there. He was astonished to hear that she contacted Pope Gregory IX. They met with Lope de Fitero and Bishop of Osma, Juan de Soria. de Fitero told them about their advancements in gunpowder and weapons. Phastos then pushed Ajak aside and asked her if they can interfere to stop the lunacy. Ajak denied it, reminding him of their determination and mission .
on the spur of the moment, they heard commotion and found out a pervert was attacking. Phastos quickly created a weapon to use while Ajak healed the wounded. They remarked on how the aberrant seemed to be controlled by something. Phastos mentioned how it ‘s never happened before. Ajak told him that it has, in Heian-Kyo and in Korea. A knight then arrived to help and caused the pervert to run away. Phastos thanked him, but asked who he was. The knight removed his helmet and revealed himself to be de Fitero. He agreed to keep their secret and even gave them his helmet. [ 4 ]

Ending the War

Phastos was called in by Ikaris and Sersi to investigate a Deviants Nest. With the rest of the Eternals, they found Kappa, who was controlling the deviants from the begin of the war. They soon defeated the deviants after Thena killed Kappa. [ 4 ]

Retelling the 500 Year War

One sidereal day, Phastos found the Reconquista Helmet and asked Sprite to create an illusion so they could tell the fib to the whole group. [ 4 ]

Defeating the Deviants

“Their weapons have become too deadly. Maybe wasn’t such a good idea helping them advance, Phastos?”
“Techlonogy is a part of their evolutionary process, Druig. It’s not exactly something that I can stop.”
“No, you can’t but I can!”
―Druig and Phastos argument.

While a war was taking place in Tenochtitlan, Phastos, Ajak, Sersi, Sprite, and Druig met with the stay of the Eternals after they had fought the remaining Deviants, when men with heavy weaponry began to massacre the natives of the area. Druig then confronted Phastos about how he helped them develop those weapons, when on the spur of the moment Thena ‘s Mahd Wy’ry caused her to fight the others unwittingly, injuring Phastos in the march. While they took Thena to lay on a pedestal and Ajak healed Phastos and the others wounds, an argument between Druig and Ajak began, resulting in Druig deserting the Eternals, and Ajak splitting up the team, telling them to go live their animation as they wanted. [ 1 ]

Giving Up on Humanity

“They’re not worth saving.”
―Phastos to Ajak

In August 1945, when United States Air Force dropped an atomic bombard on Hiroshima, Phastos visited the place in the consequence of the bombing and blamed himself for the incidental. He cried as he watched the mushroom defile above the city and was comforted by mate Eternal Ajak. Horrified by the Hiroshima bombing, Phastos gave up on humanity and swear to never aid or protect them henceforth. [ 1 ]

Starting a Family

many decades subsequently, Phastos met Ben Stoss, with them started dating and finally getting married. They had a son, named Jack Stoss, and all three of them lived in a heavily protected house in Chicago. Through his new syndicate, Phastos had finally gained religion in humanness once more, knowing that despite all of the regretful in the global there is besides a lot of good. [ 1 ]

Reuniting with the Eternals

After the death of Ajak, and the revelation of their own aim in Earth, the Eternals went after Phastos to ask for serve. When he saw Ikaris and Sersi, and they told him everything, Phastos was hesitant to help them, but his partner was able to convince him, reminding him about their son, and how they should give him a casual to grow up nowadays .

Returning to the Domo

Phastos then said adieu to his family, and went to Iraq with his colleague Eternals. There he was able to find and activate the Domo. Once inside his lab, Phastos began to work in something that could connect all the team and allow Druig to penetrate in a Celestial mind, called Uni-Mind. [ 1 ]

Ikaris ‘ Betrayal

“You are so pathetic!”
―Phastos to Ikaris

When Phastos was about able to build the devices that could create the Uni-Mind, Ikaris used his eye beams to destroy the devices, revealing he was responsible for Ajak ‘s death, that he knew all along about the Emergence and was will to kill all of them to ensure it to happen happen. Phastos expressed his disgust for Ikaris decisiveness, shouting that he does n’t live for Arishem, but he lives for his family .
The team split in two, and Phastos sided in the team that would try to stop the Emergence. He asked Sersi for her celestial communication Sphere, so he could build the devices that would connect them in the Uni-Mind, being able to finish it in time. They all suited up and took the devices. [ 1 ]

Stopping Tiamut

“I’ve been wanting to clip your wings for a long time, Ikaris!”
―Phastos to Ikaris

While Sersi, Druig, and Makkari went to the ground to stop the Emergence, Thena and Phastos stayed in the ship to distract Ikaris. That did n’t work out, as when the connection to create the Uni-Mind began, Ikaris attacked Druig and destroyed the Domo, but Makkari rescued Thena and Phastos .
While Makkari engaged in a battle against Ikaris, Phastos and the others defended themselves from a break vent caused by the Emergence. But when Sersi went closer to Tiamut so she could stop his wake up, Phastos and Thena confronted Ikaris to keep him busy. Phastos used his powers to create devices to attack and contain Ikaris, being able to control his powers for some fourth dimension. When Sersi was last able to reach Tiamut, all of the Eternals, including Ikaris and Sprite, were able to connect through the Uni-Mind, by the will of Tiamut himself, and stop the Emergence .
After the battle, Phastos rebuilt the Domo, and reunited with his family, Thena, Druig and Makkari in Ajak ‘s Homestead while watching the newsworthiness on television. The former three boarded the Domo, to travel around the Universe finding other Eternals and telling them the truth, while Phastos watched with his son the ship depart. [ 1 ]

Judged by Arishem

Some time former, Phastos was held captive by the Prime Celestial, Arishem, for sabotaging the egress of Tiamut the Communicator. He was bought there with Sersi and Kingo, so Arishem would evaluate their memories for a final opinion of the humans. [ 1 ]


“I have a family now. They give me faith again. And I see the good in humanity in them every single day.”

Phastos has helped nudge humanness ahead technologically while constantly keeping his magnificence hide in the shadows. Phastos has use technopathy exponent to protect humans and help them evolve their technologies at their own pace. In recent years, he started a kin with a partner and son. At first gear, Phastos seemed tidal bore to use his superhuman reason and technopathy to aid world in their technical development, as when he primitively invented the engine for the people of Babylon to use and seemed defeated that due to the slow rate of humanity ‘s development, he could only give them a, then vestigial, cover. however, after the nuclear bombings of Hiroshima and Nagasaki in the end of World War II, Phastos became cynical and guilt-ridden for his function in advancing world ‘s capability for destruction via the engineering he helped advance. This trauma resulted in Phastos turning his back on his humanity and abstain from using his powers to invent.

Despite his cynicism, Phastos possesses a frightful love for his kin, as to him, they are his only lens into seeing the best of world. In fact, Phastos lone took character in stopping the Emergence, not to save humanity, but to save his partner and son from the Celestials end of Earth. Phastos ‘ love for his kin is therefore great, that despite his vow not to use his powers, Phastos alone used them for the sake of protecting his family, as he created an durable sign of the zodiac for them to live in .
