Eros grew up on Titan alongside his brother Thanos, embracing all the pleasures that life has to offer. He laters becomes Starfox and an official member of the Avengers.
“Eternals” ends with half of the team choosing to remain on Earth, while the rest head back to space aboard their ship the Domo. Unfortunately for the Eternals, the Celestial Arishem is not at all pleased that they chose to stop the emergence of another Celestial in order to save humanity, so he plucks Sersi (Gemma Chan), Phastos (Brian Tyree Henry) and Kingo (Kumail Nanjiani) off of Earth to experience his wrath.
Cruising aboard the Domo are Thena (Angelina Jolie), Makkari (Lauren Ridloff) and Druig (Barry Keoghan). But the trio are suddenly joined by a curious-looking CGI fellow named Pip (Oswalt), who goes through a long list of accolades as he introduces the “Royal Prince of Titan” and “Thanos’ brother” Eros (Styles).
Eros knows the Earthbound Eternals are in trouble, but luckily he knows how to find them.
As an Eternal, Eros can harness cosmic energy for various purposes; although, he has not developed his full potential. For instance, he seems to have little or no proficiency in molecular restructuring; though, he once helped reverse one of Sersi’s transmutations. He has superhuman strength (Class 25), durability, metabolism, and regenerative powers. Immune to terrestrial disease, he is practically immortal, and also ages far more slowly than most humanoids; he is over 1000 years old.
Eros can surround himself with a personal force field, allowing for underwater and space travel, can both fly at up to 800 mph, and perform telekinetic stunts using his ability to harness gravitons. Eros can speak 500 extraterrestrial languages.
