Powers and Abilities

The Eternals’ bodily cells contain cosmic energy, and they maintain constant mental control over every molecule of their bodies. Eternals are virtually immortal, and can be restored to life even if the molecules of their bodies are scattered. All Eternals possess the capacity for superhuman strength, telepathy, flight, teleportation, illusion-casting, transmutation of organic and inorganic matter, and the generation of various forms of energy from their bodies, 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. The Eternal who serves as Prime Eternal can generate blue flame which will merge anyone who passes through it into a Uni-Mind, a powerful psychic entity which embodies the collective power of every individual who created it. A Uni-Mind requires the participation of at least seven Eternals in order to succeed.
The Eternals have complete control over their molecules. This can grant them shapeshifting abilities, healing abilities and many others. They can draw oxygen from water. They can also breath in different environments. They do not show signs of fatigue from physical activity such as running for an unlimited time without getting tired. Extended use of powers can cause fatigue. The Eternals have been shown to come back from getting their molecules dispersed. As long as a Celestial machine is running they cannot die. Their cosmic powers grant them a number of other abilities such as:
Accelerated Healing
Due to the experiments that Deviants have done on Eternals they can survive or regenerate from most anything. The Deviants have tried to fry and liquefy the Eternals organs, putting an Eternal in a smelter, a car crusher and an acid bath only for the Eternal to heal from it. They detonated a bomb in front of one and then the Eternal fell off a very high building only to heal in two days. They have tried to blow the Eternal apart from molecule to molecule and atom to atom only for the Eternal to recover.
Reincarnation
If the Eternals die they will awake in the reactivation chamber which is underground in Antarctica, in a few days.
Super Strength
The strength of an Eternal varies. An Eternal can focus their cosmic energy to increase their strength. Physically the strongest Eternal is The Forgotten One, Gilgamesh, who is capable of hurting Thor.
Project blasts: Blast of cosmic energy through their eyes or hands.
Flight: Ranging from minuscule levitation to supersonic travel. The Eternal called Ikaris is known as "the Flyer" and is capable of flying at 850 miles per hour.
Telepathy: Varying degrees of telepathic abilities.
Teleportation: They can teleport over great distances. Sersi has been shown to teleport across the United States. However, they find this method of travel unpleasant.
Transmutation: Change the objects size, shape and molecules.
Force-Field: The Eternals have a very thin force field that is so close that it is practically in their skin. This force field reduces the strength from physical attacks, heat and pressure.
Specialization
Several Eternals have taken all their cosmic power and focused it into the development of one power, ability or area while also using their extensive lifespans to master those same powers and abilities.
Sersi: Has channeled and used her cosmic energy to develop the power and mastery of molecular manipulation/transmutation.
Gilgamesh: Has harnessed his cosmic energy to develop vast levels of superhuman strength, stamina and durability; levels higher than any other Eternal.
Ikaris: Has used his cosmic power to enhance his all of his senses and his ability to fly.
Makkari: Channeled his cosmic power to develop super-speed unmatched or surpassed amongst his fellow Eternals.
Interloper: Has focused his power into developing the ability to sense and show the fear of others.
Ajak: Has developed his mental abilities in the area of language and communication.
