Eternals 2: King in Black (2025) dives deeper into the cosmic side of the Marvel Cinematic Universe, picking up after the dramatic conclusion of the first film. As the Eternals reel from Arishem’s judgment and the truth of their existence, a new threat emerges from the far reaches of the void β Knull, the god of darkness and the originator of the symbiotes. His arrival signals the beginning of a galactic extinction, as entire planets fall to his living abyss. With the Celestials absent and Earth vulnerable, the Eternals must regroup and prepare for a war unlike anything theyβve faced.
Leading the charge are Sersi, Kingo, and Thena, joined by new cosmic allies and a surprising appearance from symbiote-connected characters, hinting at a larger Marvel crossover. As Knull spreads his dark influence, corrupting beings with his living shadows, even some of the Eternals begin to question their loyalty and purpose. The moral dilemma of survival versus duty becomes central, and ancient rivalries among the Eternals resurface in the chaos.
Visually, the film promises to be a spectacle β merging otherworldly battles with shadow-infused horror. Knullβs presence brings a terrifying new tone to the MCU, blending high-stakes action with eerie, mythic dread. Massive battles unfold across stars and dimensions, including a desperate defense of Earth as it becomes the last line of resistance. With the emergence of the All-Black Necrosword, the weapon of Knull, the balance of power tips dangerously toward annihilation.
Eternals 2: King in Black raises the bar for cosmic storytelling in the MCU. It explores themes of creation, corruption, and legacy as the Eternals must confront not only a god of death but the consequences of their own actions. With emotional depth, massive world-building, and the dawn of a new cosmic era, the film sets the stage for even larger threats to come in the Marvel universe.
