Ikaris is a character in the Eternals movie, portrayed by actor Richard Madden. The character is one of the main members of the Eternals, a group of powerful beings created by the Celestials to protect Earth from the Deviants.
Throughout the movie, Ikaris is shown to be a loyal member of the Eternals and a dedicated protector of Earth. However, as the story progresses, it becomes clear that Ikaris has a hidden agenda. He is revealed to be working with the Celestials, and his true mission is to help the Celestials activate the Terraform, a machine that will allow them to consume the Earth and create new life.
In the final battle of the movie, the Eternals are faced with a difficult decision. They must either destroy the Terraform and save the Earth or allow the Celestials to consume the planet and create new life. Ikaris, who has been revealed to be a traitor, initially sides with the Celestials and tries to stop the other Eternals from destroying the Terraform.
However, Ikaris ultimately realizes the error of his ways and chooses to help the Eternals save the Earth. He sacrifices himself to destroy the Terraform, preventing the Celestials from consuming the planet and saving humanity.
So, to answer the question, yes, Ikaris is dead by the end of the Eternals movie. He sacrifices himself to save the Earth and humanity from the Celestials. His death is a heroic moment and a fitting end for his character arc.
It is worth noting that in the comics, Ikaris is known for his regenerative powers and has been shown to come back from the dead. However, it is unclear if this will be the case in the MCU.
In conclusion, Ikaris is a complex and compelling character in the Eternals movie. While he starts off as a loyal member of the Eternals, his hidden agenda and eventual redemption make for an engaging character arc. His death in the final battle is a heroic moment and a fitting end to his story.
