Ikaris is actually dead at the end of Eternals, Eternals co-writer Kaz Firpo confirms to CBR that the all-powerful Ikaris commit suicide. The third film in Phase 4 of the Marvel Cinematic Universe, Eternals, presented the Celestials‘ creation of a group of immortal beings to supervise humanity’s growth over the previous 7,000 years. Gemma Chan’s Sersi, the de facto commander following the assassination of the conduit Ajak, is among the large squad of Eternals. Although she is dating Kit Harington’s Dane Whitman throughout the events of the film, she has a millennia-long romantic past with Richard Madden’s Ikaris.
“What is the melting point of an Eternal? How long does it take to literally melt an Eternal robot?” Firpo said. “For what it’s worth… yeah, it was always that. He can’t bear to face his family after what he’s done, which he realizes.”
Though he fails his mission to sacrifice the planet so that Tiamut can be born, Ikaris tells Ajak: “Never have I doubted my purpose to serve the Celestials.”
Ever the loyal soldier, “I don’t think that Ikarus even thinks that he’s wrong,” Firpo said. “I think that he just has so much regret. He’s very sorry. I think he’s sorry for the way he lived his whole life on this planet, and that’s a lot of burdens to carry. So really, that act is basically saying, ‘I made a mistake, but I can’t face my family, and I can’t go on living.'”
On Ikaris’s suicide, Firpo explained, “It began as an exile that I think, throughout the course of the filmmaking, really became something that needed to be definitive. It really is a moment of saying, ‘It’s sacrifice.’ It’s sort of saying, ‘I can’t serve the Eternals. If I can’t serve the Celestials, and I can’t be with my family, then I choose this third option,’ which — for him — really is oblivion.”
The Eternals still have a lot of challenges to deal with, despite having prevented the Emergence, lost Ikaris, and found forgiveness for Sprite’s treachery. The arrival of Harry Styles’ Eros, as well as Dane Whitman’s perspective embrace of the Black Knight mantle under Blade’s supervision, are among these difficulties. While Ikaris will not be returning to the Marvel Cinematic Universe, the Eternals will very surely do so in a sequel.
The Eternals’ choice to kill some of the individuals featured in the film permanently is a daring move that reflects the magnitude of Phase 4 of the MCU. After the events of Endgame took a toll on the Avengers as well as the world at large, this phase is not hesitant to take huge swings and focus on the costs and sacrifices involved in being a hero. Madden’s part is completed in the MCU.
