He has also served as a member of both the Avengers and the Dark Guardians at various points in his history.

Since his original introduction in comics, Eros has been featured in various other Marvel-licensed products, including films and video games. The character made his live-action debut in the Marvel Cinematic Universe film Eternals (2021), portrayed by Harry Styles.

Development

Concept and creation Eros serves as the opposite reflection of Thanos in nearly every aspect. This contrast aligns with writer-artist Jim Starlin's intention to create two characters embodying semi-Freudian concepts: Thanatos and Eros, representing death and desire. The character was redesigned following his introduction in the Marvel Cinematic Universe (MCU).

Publication history Eros debuted in The Invincible Iron Man #55 (February 1973), created by writer and artist Jim Starlin. He appeared in 1968 Captain Marvel series, the 2022 A.X.E.: Judgment Day series, and the 2022 A.X.E.: Starfox one-shot.

Fictional character biography Eros is a member of the Eternals, a genetic offshoot of humanity, that left for deep space from Earth thousands of years ago and settled on Saturn's moon of Titan. Eros is the youngest son of A'lars (also known as Mentor) and Sui-San, the nephew of Zuras, and the grandnephew of Uranos. He grew up on Titan to be a fun-loving, carefree womanizer and adventurer in contrast to his brother Thanos, a power-hungry, nihilistic conqueror. Only when Thanos launched his first major attack on Titan did Eros begin to take life a bit more seriously.

Years later, in a subsequent campaign of terror by Thanos, Eros battles alongside Titan's handful of survivors. Eros joins the Kree Mar-Vell in battling Thanos's minions.Captain Marvel #27.

When Thanos had gained the Infinity Gauntlet, one of the first things he did was capture Starfox and place him under various torments. Starfox was forced to witness various cosmic murders, power plays, the personal deaths of heroes he knew and other atrocities. He did attempt to charm Thanos out of his plan but had his mouth neutralized for his effort.Infinity Gauntlet #2. Marvel Comics.

Starfox spent time with the son of Mar-Vell, Genis-Vell, and attempted on multiple occasions to assist him and steer him in the right direction.Cosmic Powers #2. Marvel Comics. Once, he came up with a device that would block telepathic transmissions during sexual activity.

Starfox was part of a re-gathering of Avengers when Morgan Le Fay attacked all current and ex-members.The Avengers (vol. 3) #1, 3. Marvel Comics. After an adventure in an alternate universe, Starfox left Earth with Tigra, planning to head towards a known pleasure planet.The Avengers (vol. 3) #4. Marvel Comics.

Eros and his brother, Thanos, have a custom, where each Eternal year (equivalent to 1,000 Earth years), they bury the hatchet and convene at a neutral place, usually bearing gifts. This was an initiative of their father, who demanded that the two would meet every year as a reminder of the blood that runs through both their veins. The meeting is called The Truce and the two meet alone, although the hero Quasar was present at one of their meetings, and they refuse to fight one another.Quasar #59. Marvel Comics.

Eros is bisexual, having been seen in an orgy in which both males and females serve him sexually; he invited Tryco Slatterus, the Champion of the Universe, to join them, but the latter declined.Thanos (Vol. 2) #1. Marvel Comics.

Allegations of sexual assault Starfox was put on trial for sexual assault, accused of using his powers to seduce a happily married woman. He was defended by lawyer Jennifer Walters, the She-Hulk. The law firm which employed her, Goodman, Lieber, Kurtzberg & Holliway, was contracted by Mentor to defend his son from the allegations. In the course of the trial, Walters came to suspect that Starfox had used his powers on her during their time in the Avengers, resulting in a brief sexual interaction. By this time, Starfox had been banned from the courtroom after it was determined that he was using his special abilities to influence the witnesses. When Walters confronted Starfox with her suspicions via closed-circuit video link, he evaded her questions and then cut the video feed. Walters angrily charged out of the courtroom, transformed into She-Hulk, and caught Starfox as he was attempting to escape from Earth. She-Hulk dealt Starfox a savage beating, giving him no chance to defend his actions, knocked him unconscious, finally duct-taping his mouth shut to ensure that he could not use his abilities to elude punishment. However, Mentor, Starfox's father, effected his son's release by teleporting Starfox away to Titan.She-Hulk (vol. 2) #6–7. Marvel Comics.

Mentor eventually staged a native Titanian trial in the hopes of clearing his son's name. The Living Tribunal, interested in the equity of the process, called on She-Hulk as prosecuting attorney. Jennifer Walters, in an attempt to get to the bottom of the matter, agreed to a mind probe of both Starfox and herself. She discovered that Starfox did not use his abilities to influence her decision to have sex with him, but that he was deliberately responsible for her sudden infatuation with and marriage to John Jameson. An enraged She-Hulk once more lashed out at Starfox for toying with her life, bringing the legal proceedings to a halt.She-Hulk (vol. 2) #12–13. Marvel Comics.

Thanos now appeared at the trial and testified that his brother, Starfox, inspired his obsession with Death when they were children, when attempting to make young Thanos accept the death of an animal he had involuntarily killed with his enormous strength. By Titanian law, Eros would thus take full responsibility for all the genocides Thanos had later committed. In the following issue, it was revealed that this was a false memory that Thanos implanted into Starfox's mind and shared by a Thanos clone that the real Thanos sent. Thanos' implantation of the memory is what caused Starfox to briefly become mentally unbalanced and use his power in this manner for the first time. Starfox agreed to have Moondragon shut them off completely rather than risk hurting more people.She-Hulk (vol. 2) #6–13. Marvel Comics.

Return Starfox is later seen living on Titan again, with his abilities restored. He is shown flirting with a number of women, but states that he will not use his powers to woo them. Ultron soon attacks Titan and assimilates the entire population (including Mentor) via a robotic virus, transforming the moon into Planet Ultron. Starfox flees to Earth and meets with the current team of Avengers (now led by the new Captain America), and teams up with them to liberate his world. He plays a key role in the Avengers' victory, using his powers on the half-organic Ultron to force the villain to have an emotional breakdown.Avengers: Rage of Ultron. Marvel Comics.

Infinity Conflict In Thanos: The Infinity Siblings, after sleeping with different women on Titan, Eros is suddenly teleported into the future by his future self and is left stranded on a prehistoric world. Following a number of years, in the year 2079, his handmade radio finally caught a signal of a ship which rescued Eros. Then in the year 2125, Eros is forced to do an emergency landing due to his ship being damaged. He landed on the planet Zelchia which is ten times the size of Earth with a much higher gravity. Being unable to fly Eros is knocked out by the savage natives who plan to eat him. Thankfully, he is saved by the owl-like mutant native with teleporting powers named only Ghost. Ghost took Eros to his tribe, with the latter promising Ghost to technologically advance his people. After a year Eros bid them farewell and left Zelchia and went to the planet of Shangranna. He trained on the planet for a number of years until in the year 3812 he set this entire world ablaze. Then, in the year 4012, he encounters Kang the Conqueror, whose ship was partially destroyed by the stygian darkness of an omnipotent Thanos from the year 4657. After some negotiating, Kang tells Eros about the omnipotent Thanos losing to Hunger. Eros uses Kang time traveling technology to go back to the point he was originally transported to the future and sending his past self to the same future. After recruiting Pip to this cause, he then goes to Thanos and tells him about his omnipotent future self. He then proposes to Thanos a plan to avoid the darkness from destroying all of reality. After that, Eros and Pip go through time and arrived to the point where Eros first met Kang and stole some of Kang's time-travelling technology. They use the technology to go to the point where Eros departed Zelchia and offers Ghost and his people even more advanced weaponry from the Shi'ar. After a year, Eros manages to unite the planet's three main races to fight the threat of Thanos and his army, which was really all part of his plan. As Thanos and his army are about to attack the people of Zelchia, Eros teleports in front of Thanos and uses some drug to make him appear like Thanos killed him. After regaining himself and berating Thanos for the change of plans, he, Pip, and Ghost return to the present, not knowing that he was secretly manipulated by the future Omnipotent Thanos this whole time.Thanos: The Infinity Siblings #1.
