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. Following a trip to Mystery Planet, Eros was given the name Starfox. 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.
