- Been There, Shaped History: Being a race of long-lived superpowered beings, the Eternals inspired some of mankind's legends.
- Complete Immortality: Eternas can't die of old age and have complete control over their bodies' molecules unless knocked out. They can be injured or weakened, though.
- Eye Beams: The Eternals can fire cosmic energy through their eyes.
- Driven to Suicide: During Avengers (2018) most of the Eternals committed suicide after being driven mad by the imminent arrival of the Dark Celestials.
- Back from the Dead: After being dead for almost two years, every Eternal that died returns for the 2021 run.
- Flying Brick: The entire race has this power set, in addition to other assorted individual powers that each develops through millennia of practice and training.
- Hand Blast: Eternals can also fire destructive blasts from their hands.
- Healing Factor: On the rare occasions an Eternal is physically harmed by some extreme force, they can heal themselves using their molecular control powers. Injuries such as lacerations or bullet wounds can fully mend within a matter of hours. This ability can be augmented dramatically if they properly train themselves.
- Human Subspecies: As a result of the Celestials' genetic tinkering.
- Immortal Procreation Clause: After a retcon, the Eternals are completely infertile with each other, since they are Nigh Invulnerable, simply regenerate when you do hurt them, and are eternally young. Several of them have sired completely normal baseline human offspring with mortal lovers/spouses over the centuries, but this presents other problems. Originally, the Eternals could and did procreate, albeit very rarely and many Eternals were noted as being the children of other Eternals and born long after the Celestials created their race.
- Nigh-Invulnerability: While a lot of super heroic characters have some level of invulnerability, the Eternals may stand out for special mention: they possess a "psychic lock" on their molecular structure that allows them to restore virtually any injury they can't flat-out ignore.
- Society of Immortals: The Eternals have historically maintained their own secret cities but sometimes hang around with mortal humans for kicks. To illustrate the difference this trope creates in mindset, there was a dialogue in an issue of The Avengers where Sersi was asked by one of her (mortal) teammates what the Eternals' beliefs regarding ghosts were. Sersi responded that the topic does not get discussed much in their culture because they don't die.
- Teleporters and Transporters: They can teleport themselves and others across vast distances, although doing so is unpleasant for them.
Eternals of Earth
Notable Aliases: Quetzacoatl, Tecumotzin, Lord of Flight, Ajax the Greater, He Who Talks To Celestials
First Appearance: The Eternals #2 (August 1976)
The Eternal spokesman for the Third and Fourth host of the Celestials on Earth.
Notable Aliases: Ivan Druig, Druig of Nightmares
First Appearance: The Eternals #11 (May 1977)
Druig, Lord of Flames and Nightmares, is the Polarian Eternal son of Valkin, and cousin to Ikaris. A power hungry schemer, Druig was a disappointment to his father, who nevertheless turned a blind eye to Druig's faults.
- Beard of Evil: Has a goatee, and is one of the few Eternals that are evil.
- Clashing Cousins: He's the biggest foe of his cousin Ikaris.
- Red and Black and Evil All Over: His armor is mostly red and black. Most of the outfits he wears are black and red.
- Token Evil Teammate: He's the only Eternal associated with Olympia that is evil.
- Trauma Button: One of Druig's powers is the ability to find people's deepest, darkest fears and exploit them to control their minds.
The Forgotten One
Notable Aliases: Gilgamesh, Hero, Gil, Hero of Sumer, Lost Eternal, Beloved of the Muses, Dragon-Slayer, Forgotten Nemesis, Beast of Legend, King Gilgamesh
First Appearance: The Eternals #13 (July 1977)
His true name lost in the mists of time, The Forgotten One is a member of the immortal race called the Eternals. He has been known by many names, most notably Gilgamesh, but he is once more who he must ever be: The Forgotten One.
- Boisterous Bruiser
- Complete Immortality: As an Eternal, he can't die of old age and has complete control over his body's molecules unless knocked out. He can be injured or weakened, though.
- Eternal Hero: The definitive article right here — he inspired the universal concept of the Hero archetype in humanity's collective unconscious in the first place. He is essentially The Hero with a Thousand Faces manifest. Fittingly, he sometimes simply goes by "Hero" like he owns the word. Plus, his main moniker doesn't exactly roll off the tongue, so who can blame him?
- Eye Beams: He can fire cosmic energy through his eyes.
- Flying Brick: Like most Eternals, he has superhuman strength and can fly.
- The Fog of Ages: Having walked amongst fleeting humanity for millennia, the Forgotten One embodies the wandering immortal trope best of all the Eternals. He's acted as a guardian or ruler of innumerable civilizations and his many names are scribed in legend and folklore throughout the world. But the tragic irony is that nobody really knows anything about him, not even his real name.
- Hand Blast: He can also fire destructive blasts from his hands.
- Human Subspecies: A member of the Eternals.
- I Have Many Names: He has taken on countless identities throughout human history, including legendary heroes from various mythologies such as Hercules, Samson, Atlas and Beowulf, but his most synonymous alias is Gilgamesh. (Though it gets a bit confusing when you realize that all of these characters also exist independently in the Marvel Universe as well...)
- Mistaken Identity: In ancient times he was mistaken for Hercules and a few other "mythic" strongmen. Which created a mild Continuity Snarl, because The Incredible Hercules is already a character in Marvel canon. Herc's own series took care to Retcon and explain Gilgamesh's claim to have been Hercules.
- Really 700 Years Old: Like all Eternals, he's thousands of years old.
- Super Strength: Even among his fellow Eternals, his strength is renowned. He's able to trade blows with Thor and Hercules without too much effort.
Notable Aliases: "Iceberg" Ike Harris, Sovereign, Isaac "Ike" Harris, Daedalus

- Clashing Cousins: He and his cousin Druig are each other's worst enemies.
- Eye Beams: One of his favorite party tricks.
- Flying Brick: Ikaris can levitate himself by mentally manipulating gravitons (subatomic particles carrying the force of gravitational attraction between atoms) around himself. He can also levitate other persons and objects, even while simultaneously levitating himself.
- Meaningful Name: Changed his name from Daedalus to Ikaris after the death of his son Icarus.
- Primary-Color Champion: Has blonde hair and his outfit is red and blue. He's also one of the nicer Eternals.
First Appearance: The Eternals #11 (May 1977)
Kingo Sunen is a samurai, master swordsman, film star and producer.
Notable Aliases: Mike Khary, Frank Harper, Mark Curry, Jake Curtiss, Major Mercury, Hurricane, Mercury, Adam Clayton, Mac Curry, Michael Gray, Thoth
First Appearance: Red Raven Comics #1 (August 1940) note ; Captain America Comics #1 (March 1941) note ; The Eternals #5 (November 1976) note
Makkari is the fastest speedster of the Eternals.
- Composite Character: Mercury and Hurricane, two seemingly unrelated Golden Age speedsters, were recently retconned into having been disguises of Makkari.
- Crippling Overspecialization: He once gave up all of his other Eternal powers in exchange for being able to solely focus on improving his already impressive Super Speed.
- Gender Bender: To match up with the Marvel Cinematic Universe's portrayal of the character, Makkari was turned into a female for the 2021 run.
- Super Speed: Makkari has devoted the majority of his Eternal energies to the improvement of his personal speed. He can create cyclones by running in circles, and can run up walls and across water. At one point in his life, Makkari trained with the Eternal guru Elo to boost his speed to unprecedented levels, making him one of the fastest beings in the entire Marvel Universe.
Notable Aliases: Hephaestus, Vulcan, Ceasefire, Phillip Stoss
First Appearance: The Eternals Vol. 2 #1 (October 1985)
Eternal who was often mistaken for the Greek god Hephaestus. He built most of the Eternals' devices, including the sword of Kingo Sunen and the flight harness used by Icarus. The hammer Phastos carries has the power to manipulate machinery in ways the Eternals' own matter control powers can not.
Notable Aliases: Circe, Sylvia Sersy, Mesmer, Sorceress
First Appearance: Strange Tales #109 (June 1963) note ; The Eternals #3 (September 1976) note
Sersi is an Eternal. She is the daughter of Helios and Perse. Sersi is the only fifth level adept, the highest possible, among the Eternals in the discipline of matter rearrangement. Sersi became associated with the Avengers after inviting them to one of her parties and meeting her long-lost "cousin" Starfox of the Titan Eternals.
- Baleful Polymorph: Sersi is able to transmute nearly any item or being into almost whatever she wishes.
- Battle Couple: With Avengers teammate Dane Whitman, the Black Knight.
- Been There, Shaped History: Sersi is the sorceress Circe from Greek Mythology.Sersi: The Greek storytellers could never spell my name right.
- The Dreaded: Amongst the Eternals it's said that even Prime-Eternal Zuras, mightiest of all Eternals, fears the power of Sersi.
- Flying Brick: She can fly at high speeds through telekinesis.
- Hard-Drinking Party Girl: She is the most fun-loving and hedonistic of the Eternals, much to Thena's annoyance.
- Healing Factor: On the rare occasions Sersi is physically harmed by some extreme force, she can heal herself using her molecular control powers. Sersi once reconstructed her own arm after it was disintegrated by a Deviant weapon
- Human Subspecies: Sersi is a fourth generation member of the Eternals, an evolutionary offshoot of the human race.
- Immortality: Nearly. Eternals like Sersi possess total conscious control over their molecular structures, which are reinforced by cosmic energy. As a result, they are virtually immortal and indestructible.
- Interspecies Romance: Anytime she has a relationship with a human it counts as this, but most specifically with her teammate Dane Whitman, the second Black Knight.
- Master of Illusion: Sersi is skilled in the use of illusions. Her illusions affect all five senses and are virtually indistinguishable from the 'real thing'. Her illusions are so effective, it's often difficult to tell whether she is employing illusions or her matter-rearranging abilities.
- Most Common Superpower: She has a voluptuous body with huge breasts. What Powergirl does for the JSA, Sersi does for the Avengers.
- Ms. Fanservice: When you're initially conceived as a "flirtatious demi-goddess not afraid to take her clothes off" in the 1970's, you know you're destined to be this kind of character.
- Really Gets Around: According to Sprite, she slept with every adult male Eternal, all sixty of them.
- Really 700 Years Old: Sersi has existed for many years, although she seems to be considered one of the younger Eternals.
- She's Got Legs: Most all of her many costumes show them off.
- Purple Is Powerful: For her return on the 2021 series she trades her green outfit for a purple one. She remains as powerful as ever.
- The Tease: During her time with the Avengers, she started a flirtation with Captain America (much to his embarrassment).
- Telepathy: Sersi can psychically communicate, read minds, and project her thoughts into other people. She can compel the distracted or weak minded to do her bidding through hypnosis
- Teleporters and Transporters: She can teleport herself and others across vast distances although doing so is unpleasant for Eternals.
- Transmutation: Sersi's special ability is matter rearrangement and she is the only fifth level adept (the highest level possible among Eternals) in that discipline. Amongst the Eternals it is said that even Prime-Eternal Zuras, the mightiest of all Eternals, fear her.
Notable Aliases: Puck, Robin Goodfellow, Colín, Peter Frickin' Pan
First Appearance: The Eternals #9 (March 1977)
The trickster Eternal. Sprite looks like a child.
- Bratty Half-Pint: Sprite is one highly annoying little bastard.
- Gender Bender: Ends up being revived as a female during the 2021 comic series.
- Immortal Immaturity: He's not very mature because of his inability to grow.
- Lady Looks Like a Dude: Being the same age, when Sprite is revived as female, she doesn't look much different than when she was male.
- Not Growing Up Sucks: Has become very disillusioned with being stuck as a child for millennia.
- Really 700 Years Old: Is millennia old but looks (and acts) like a young child.
- The Trickster: He pranked humans for centuries under various guises, inspiring Shakespeare's character of the same name.
Alter Ego: Azura (birth name)
Notable Aliases: Thena Eliot, Athena, Zura, Betty Sue Bialovsky, Prime Eternal
First Appearance: Red Raven Comics #1 (August 1940) note ; The Eternals #5 (November 1976) note ; New Eternals: Apocalypse Now #1 (February 2000) note
Thena is the daughter of Zuras and Cybele. Thena is also the niece of A'lars and cousin to Thanos and Eros Starfox. She is also the mother of Deborah and Donald Ritter, as well as Joey Eliot. Thena is the occasional lover of the Deviant Kro and once served as the Prime Eternal.
- Badass Cape: Thena is usually seen with a red cape.
- Blade on a Stick: Her sort of spear-axe that's her default weapon.
- Bling of War: Her golden armor is quite impressive.
- Healing Factor: Thena's psionic control over her body's molecules allows her to rapidly regenerate from virtually any injury short of having her molecules dispersed over a wide area, even while asleep or unconscious.
- Light Feminine Dark Feminine: She seems to be the light to Sersi's dark.
- Nigh-Invulnerability: Thena's Eternal body is highly resistant to injury due to her psionic control over her body's molecules. She is mostly invulnerable to conventional weaponry and can only be killed by dispersing her body's molecules over a wide area.
- Statuesque Stunner: She's 5'10"/178cm tall and very beautiful.
- You Are in Command Now: Became the leader of the Eternals for a time after the death of her father Zuras.
Notable Aliases: Father Zuras, Jupiter, Prime Eternal, (Zuras has often been mistaken for the Olympian god Zeus)
First Appearance: Red Raven Comics #1 (August 1940) note ; The Eternals #5 (November 1976) note
Zuras is the son of Kronos, brother of A'Lars (Mentor) and father of Thena. He rules Earth's Eternals, from Olympia, as the Prime-Eternal.
- A God I Am Not: In the Gaiman miniseries, he forbiddingly points out to Iron Man that the Eternals were worshipped by humans as their gods. Iron Man, less than fazed, points out that he knows gods, and Zuras is not a god. Zuras cracks up and agrees with him.
- Alternate Company Equivalent: Can be seen as the counterpart of DC's Highfather, being the bearded ruler of an immortal race.
- Back from the Dead: After being dead for several years and serving as a Spirit Advisor, he was resurrected during the Neil Gaiman mini-series.
- Badass Beard: Has a red beard and is the leader of Earth's Eternals.
- Evil Nephew: His nephew happens to be Thanos.
- Reasonable Authority Figure: He's quite reasonable as leader of the Eternals... usually. He was up to some pretty questionable things in the 2014 New Warriors run.
Eternals of Titan
Notable Aliases: Mentor
First Appearance: Iron Man #55 (Febuary 1973)
A'lars - descendant of the Titan Kronos, Father to the Demi-Gods Thanos and Eros, Grandfather of Thane. A'lars, more commonly referred to as The Mentor, became the founder of the colony orbiting the planet of Saturn. Engineer, physicist, father - The Mentor would shape many cosmic characters.
- Antagonistic Offspring: After turning a blind eye for many years, A'Lars is eventually forced into conflict against his genocidal, Death-worshipping son Thanos.
- Cassandra Truth: His wife Sui-San attempted to kill an infant Thanos shortly after his birth, claiming to see "Death in his eyes". A'Lars had her institutionalised and ignored her warnings until it was too late.
- Devil in Plain Sight: While Thanos was shunned by everyone in Titanian society, including his own mother, because of his hideous deformities, A'Lars loved and accepted him throughout his adolescent years and initially refused to acknowledge Thanos's growing psychotic tendencies.
- Dying Declaration of Hate: After Thanos attempts to blackmail his father into helping him find the cure for a fatal affliction, A'Lars reveals that he too is dying and proceeds to give his tyrannical despot of a son one hell of a final call-out, telling Thanos to his face that he was a mistake who should have died at birth, provoking the Mad Titan into ending his suffering.
- Killed Off for Real: By Thanos, though A'Lars was dying anyway.
- This is contradicted by Jim Starlin's Infinity Siblings graphic novel, where Eros tells Thanos that Mentor died in Rage of Ultron when Ultron took over Titan.
- One Steve Limit: His moniker of Mentor is shared with a member of the Shi'ar Imperial Guard.
Notable Aliases: Eron (Birth Name), Starfox
First Appearance: Iron Man #55 (February 1973)
Eros is the youngest son of A'lar Mentor and is Thanos' younger brother. Eros is also an Eternal and Avenger.
- Amazon Chaser: He has a particular interest in Earth's many superhuman women, such as She-Hulk. It seems to give him an ego boost that he can "tame" them (with some questionable applications of his powers, mainly).
- Brilliant, but Lazy: As an Eternal, Eros has a godly amount of innate potential, but he'd rather refine his seduction abilities than train his body or mind to their fullest despite having millennia to do so. His older future self from Infinity Siblings overcame his laziness and became a more proactive hero, helping Adam Warlock and Pip the Troll to stop Future Thanos from assimilating the cosmic entities.
- Cain and Abel: As a handsome, fun-loving womaniser, he is the polar opposite to his deformed, thoroughly evil brother Thanos. Although he's not exactly the most moral guy, it's a task to not look like a saint when Thanos is your sibling.
- The Casanova: In close competition with Tony Stark for the title of most prolific womaniser in the Marvel Universe.
- Character Development: In the Infinity Siblings graphic novel, being stranded on a jungle planet for many years pushed Eros to become more proactive and less selfish.
- Combo Platter Powers
- Extreme Omnisexual: In the first issue of the 2016 Thanos series, Starfox is shown in an orgy with aliens from various species and genders. When the Champion of the Universe enters the room, Starfox's first impulse is to invite him to come get in on the action.
- Flying Brick
- Groin Attack: He was infamously on the receiving end of a vicious one from She-Hulk after she discovered that he had used his Living Aphrodisiac powers to coerce her into a relationship. He's lucky to still even have balls after that, but it's hard to feel sorry for him.
- Healing Factor: While it is not as advanced as other members of his species, Eros still has this. If he is injured, his physiology enables him to recover much faster and more extensively than a human being is capable of. Injuries such as lacerations or bullet wounds can fully mend within a matter of hours. This ability can be augmented dramatically if Starfox properly trains himself.
- The Hedonist: Spends all of his immortal life pursuing earthly pleasures.
- Immortality Begins at Twenty: Starfox, like all Eternals, is essentially immortal. The cosmic energy housed in his body has been developed for the purpose of halting his natural aging process. Although well over 1,000 years old, he is still physically young by Eternal standards.
- Immortality Promiscuity: Virtually immortal, but unlike his nihilistic brother Eros is a care-free womanizer.
- Living Aphrodisiac: He passively emits pleasure stimulation in others wherever he goes, but he can amp it up to anything from arousal to uncontrollable lust on a whim. This results in some In-Universe Unfortunate Implications and Questionable Consent as he has used his powers to manipulate countless women (and some men) into sex or long-term relationships throughout the centuries.
- Obfuscating Stupidity: As Tryco Slatterus points out in the 2016 Thanos series, he's much smarter than he lets on - the debauched hedonist and fun-loving adventurer acts are just that, acts, which he uses to get people to let their guard down. When he drops the act, he's a much more serious - and much more dangerous - individual.
- Older and Wiser: In the recent graphic novel Infinity Siblings and its two sequels, Eros became this in a alternate future where he got stranded on a wild planet and forced to drop his hedonism in order to survive.
- Power Perversion Potential: He has the power to control the emotions of others. In one She-Hulk arc, a suit was brought against him by some, including She-Hulk herself, who may have been forced into sex with him thanks to his powers. (The man's real name is Eros, after all).
- Super Strength: Eros can lift around 15 tons, which is actually on the low end compared to others of his species (guys like Hyperion can lift 70 tons while Gilgamesh and early Thanos are Class 100, while even non-melee females like Sersi and Azura are stronger).
- Super Toughness: He's not bulletproof, but he's still pretty tough.
Notable Aliases: Chronos
First Appearance: Iron Man #55 (February 1973)
A mysterious and rarely seen Eternal, the cosmic master of time within the Marvel continuum remains a powerful figure within the universe's large landscape. Once a Titan when the universe was young - he now resides between the space/time continuum as an ominous figure observing matters of galactic importance.
Notable Aliases: The Mad Titan
First Appearance: The Invincible Iron Man #55 (February 1973)
