The engineer and Eternal Phastos is a superhuman created by the Celestials, and he uses his knowledge and powers to aid his people until his search for something more to life keeps him on Earth.
Deviant Origins
Phastos is one of the Eternals, created cosmic beings called the Celestials around one million years ago during the Celestials’ First Host and tasked with safeguarding Earth. Their immortality and near limitless power are unlike anything humanity has ever known.
As an Eternal, Phastos is distantly related to the genetically unstable Deviants (also descended from Celestial experiments) and normal humans but possesses cosmic energy within his body, which immediately sets him and other Eternals apart from the other races. However, the Deviants raise Phastos before he leaves their ugly world to seek his destiny.
The Eternals establish a society separate from the Deviants and humans, having little to do with either race for many centuries. Phastos becomes the Eternal’s weapons smith and engineer on Earth in the city of Olympia, but his true passion lay in the pursuit of knowledge, understanding, and truth.
Cosmic Energy Manipulation
As an Eternal, Phastos’ bodily cells contain cosmic energy, and he maintains constant mental control over every molecule of his body. He is virtually immortal and can be restored to life even if the molecules of his body are scattered.
He also possesses the capacity for superhuman strength, telepathy, flight, teleportation, illusion-casting, and matter transmutation. As an Eternal, he can also generate various forms of energy from his body, including force, heat, light, and other electromagnetic radiation. Some Eternals have devoted themselves to specializing in a particular facet of their powers, and can increase their proficiency in one area by decreasing their power in another.
After Kronos, the leader of the Eternals, isolated the cosmic energy that empowered the their people, the containment vessel ruptured and exploded, disintegrating him and destroying Titanos. While Kronos exists as a disembodied cosmic entity whose life force and consciousness expands throughout the solar system, the remaining Eternals’ powers increase by the explosion’s energies. Zuras becomes the Eternals’ leader.
Phastos and the other Eternals discover that with their new powers, they can unite to form the collective Uni-Mind, merging into a single form to make decisions for their race together.
Eternal Enemies (For a Time)
The Deviant race and their Warlord Kro often go head to head with the Eternals, and while Phastos defends his people and aids them with his powers, he often expresses dissent towards any conflict, aggression, and war. Eventually, Phastos remains with the Deviants to help them solve the deadly plague that’s killing their race to save his friend Ransak and give the Deviants a fighting chance.
Duty-Bound Allies
As an Eternal, Phastos is duty-bound to his people and acts as their engineer solving their weaponry and technical problems for centuries. He even invents the reactivation chamber, a device that can heal or resurrect Eternals, which effectively makes them immortal.
Thor Odinson, AKA Thor, often allies with the Eternals, and seeks their alliance when the Deviant Ereshkigal seeks to hold ultimate power over the Deviants by using an alien stone that could unravel dimensions. To fix the broken reactivation chamber which the Deviants stole, Thor travels to the Savage Land with Phastos, who believes that the element Vibranium is needed to solve their problems—though Phastos eventually tells Thor the truth that the Vibranium could be used to stop the destructive stone from annihilating the Deviants.
