"The great adventurer... Starfox of Mystery Planet."
Pip the Troll[src]

Eros, also known as Starfox, is a member of the genetically-engineered Eternals. Created by Arishem the Judge in the World Forge, he was stationed on Titan, joining the royal family as a prince and becoming the adoptive brother of Thanos. However, he elected to desert Arishem's ideals and fled Titan, becoming a space outlaw. Creating Pip the Troll as a companion, Starfox traveled the cosmos and had adventures such as arriving on Mystery Planet and defeating Black Roger. Upon discovering that another group of Eternals had also defied Arishem, Starfox introduced himself to them, informing them that he could help them find other Eternals.


Early Life

Prince of Titan

"The royal prince of Titan, brother of Thanos, the Knave of Hearts."
Pip the Troll[src]

Eros was created by Arishem the Judge and was stationed along with nine other Eternals on Titan. There, he joined the royal family of Titan and was given the mantle of Prince, becoming the adoptive brother of Thanos. Prior to Titan's demise, Eros rebelled against Arishem and fled Titan, becoming an outlaw. While traveling through the cosmos, he created Pip the Troll to be his companion.[2] Following a trip to Mystery Planet, Eros was given the name Starfox.[1]

Defeating Black Roger

"Defeater of Black Robert..."
"Oh. Defeater of Black Roger."
Pip the Troll and Starfox[src]

On one journey, Eros and Pip the Troll encountered a being called Black Roger. When Black Roger was deemed an adversary, Eros defeated him. This act greatly affected Pip, who admired Eros and went on to introduce him to those they met as the defeater of Black Roger.[1]

Meeting Eternals

Arriving on the Domo

Starfox offers a partnership to the Eternals

"What do you want, lads?"
"Pip and I here to help, aren't we? Your friends are in big trouble. And we know where to find them."
Druig and Starfox[src]

In late 2023, upon learning about Arishem’s judgment, Eros transported himself alongside Pip to the Domo, where he met with three Eternals, Thena, Makkari, and Druig. Druig asked him why they were there and Eros, with a Celestial Communication Sphere in his hands, declared that he knew where their friends were, offering his partnership.[1]


"What a pleasure to make your acquaintance, my fellow Eternals."
―Starfox to Thena, Makkari and Druig[src]

In contrast to his adoptive brother Thanos, Eros appears much more jovial and existential, spending his time traversing the galaxy in search of adventure and aiding those in need. He is naturally helpful and kind-hearted, being willing to assist the Eternals in locating their captured friends.
