The first trailer for Eternals 2: King in Black (2025) opens with a dark and foreboding tone, signaling the arrival of one of the Marvel Universe’s most dangerous threats yet. Kit Harington’s Black Knight, now stepping into his own as a key figure, takes center stage in this epic sequel that ties the Eternals to a cosmic battle of unimaginable proportions.
The trailer begins with a haunting image of the Earth enveloped in darkness, swirling with inky black tendrils creeping across the skies. A voiceover from Sersi (Gemma Chan) echoes: “We thought we saved the world… but something much darker is coming.” The camera pans to the Eternals, scattered across the globe, all sensing the presence of a new menace. They look weary, having endured the cosmic repercussions of their last battle.
Enter Dane Whitman (Kit Harington), the Black Knight. We see him in London, staring at the cursed Ebony Blade that he now wields. His voiceover reflects his internal conflict: “I never wanted this power, but now the blade is a part of me.” Quick flashes show him grappling with the sword’s dark influence, as it whispers in his mind. We catch a glimpse of his relationship with Sersi, their bond still strong but strained by the immense responsibility they both carry.
The villainous force behind the chaos is revealed—Knull, the King in Black, played by a shadowy, menacing figure (rumored to be portrayed by Bill Skarsgård). The trailer showcases his army of symbiotes spreading across the universe, consuming planets and enslaving beings under his control. His deep, chilling voice declares: “I am the end of light. All will kneel to the void.”
The Eternals, including Ikaris (Richard Madden) who is mysteriously resurrected, gather once more to face this overwhelming threat. Epic battle scenes show them fighting off Knull’s forces, their powers pushed to the limit. Thena (Angelina Jolie) engages in a stunning fight sequence, her celestial weapons slicing through hordes of symbiotes, while Kingo (Kumail Nanjiani) unleashes powerful blasts of energy in a visually stunning display.
The tension rises as Dane Whitman, fully embracing the mantle of the Black Knight, rides into battle atop a black steed. His armor, now glowing with a dark energy from the Ebony Blade, suggests that he is teetering on the edge of control. The trailer teases his showdown with Knull, as the two exchange blows in a cosmic landscape, the sword clashing against Knull’s tendrils of darkness. “You think you control the darkness,” Dane says, “but I’ve learned to live with mine.”
As the trailer builds to its climax, there are quick flashes of several pivotal moments: Sprite (Lia McHugh) confronting her past, Druig (Barry Keoghan) attempting to manipulate Knull’s mind, and a hint of the Celestials watching from the edge of the galaxy. The stakes are higher than ever, with the very fabric of reality hanging in the balance.
The final shot shows the Eternals and Black Knight standing together, bruised but ready for the final confrontation with Knull. The title Eternals 2: King in Black appears, followed by the tagline: “The darkness is rising.”
This trailer promises an intense, cosmic battle that not only deepens the lore of the MCU but introduces the terrifying King in Black and sets Black Knight on a path to becoming one of the most powerful heroes in the universe.
