Eternals: King in Black (2025) – When Gods Face the Darkness Beyond the Stars

"From the edge of the cosmos comes the end of all gods."

Eternals: King in Black (2025) is a sweeping cosmic epic that merges Marvel’s immortal guardians with one of the most fearsome forces in the universe — Knull, the God of the Symbiotes. Set after the events of the Deviant War, the Eternals find their eternal vigilance tested when a vast shadow descends upon the galaxy. Worlds fall silent, stars are swallowed in black, and an ancient hunger awakens at the edge of creation.

Ikaris, still haunted by the choices that fractured the Eternals, becomes the reluctant spearhead of their defense against the encroaching darkness. Alongside Sersi, Thena, Kingo, and the rest of the immortal pantheon, he must navigate not only the terror of an enemy that can consume even gods, but also the mistrust lingering among their own ranks. Their immortality, once a shield, now becomes a curse — for Knull’s power can corrupt and twist even the ageless.

The film shifts between breathtaking celestial vistas and moments of stark, claustrophobic horror as the symbiote plague spreads from planet to planet. Director Chloé Zhao blends operatic scale with intimate emotional beats, exploring the vulnerability of beings who have lived for millennia yet find themselves unprepared for the primal, all-consuming void. Every battle is both physical and psychological, testing the Eternals’ will to endure.

At its core, Eternals: King in Black examines the nature of light in the face of unending dark. Sacrifices are made, alliances are forged with unexpected cosmic entities, and the Eternals must confront a truth they have long avoided — that some wars cannot be won, only survived.

The climax delivers a staggering visual spectacle: a war fought across starfields, blackened skies raining symbiote horrors, and the desperate, final stand of immortals who refuse to kneel. The ending leaves the universe forever changed, setting the stage for the next great cosmic reckoning in the Marvel saga.
