Who is Harry Styles playing in 'Eternals'?

Harry Styles is reportedly playing Thanos' biological brother Eros (who was initially named Eron). Eros in the comics is also known by the mantle of Starfox and as "The Knave of Hearts".

Eros is the youngest son of Titan's Eternals, A'Lars, and Sui-San.

The character is quite different from his elder brother Thanos. The latter was born with Deviant Syndrome, which caused his body to mutate and develop a purple hide and massive size compared to other progeny.

Eros is just like other Eternals in appearance and is known to be lighthearted and carefree. He is also deemed a womanizer who has had several lovers. The Titan native's only long-term relationship was with a pr*stitute, Heater Delight.

He has worked alongside The Avengers, and Captain Mar-Vell after Thanos' first attack on Titan left their mother Sui-San dead in the comics.

As a progeny of the Eternals race, Eros has enhanced intellect, super strength, speed, and more. The eternal can control gravitons which enables him to fly. With access to cosmic energy in his body, like all Eternals, Eros is practically immortal.

Amongst all these powers, Eros' primary ability is Pleasure Stimulation. The character's psionic ability enables him to stimulate the brain's pleasure nodes of anyone within a proximity of 25 feet from Eros. His stimulation can make individuals feel aroused and ecstatic.

Eros also has the ability to form Emotional Bridges, which tethers the minds of two people enabling them to share feelings and emotions with each other. This ability has allowed Eros to make people fall in love with him or with other individuals.

Here's how fans have been reacting to Harry Styles joining MCU in 'Eternals' as Eros

In a surprise to no one, the news of the 27-year-old Grammy-winning English artist joining the MCU caused several fans to be thrilled. Many took to Twitter to share their exuberant reactions to his casting.

Eros and Thanos are cousins to the Eternal Thena, one of the main characters in the movie, played by Angelina Jolie. Harry Styles' appearance as Eros could have been done while exploring the past of Thena or in a scene where he interacts with Jolie's character.

Eros' connection with Thena might be a way in which the character will show up in future MCU properties.
