The White Wolf (2025) teaser trailer opens with a haunting, snow-covered landscape in the heart of Wakanda’s northern mountains. The camera pans slowly through a thick forest, the silence broken only by the soft crunch of footsteps on the snow. Emerging from the shadows is none other than Bucky Barnes (Sebastian Stan), now fully embracing his new identity as the White Wolf. He’s draped in a fur-lined cloak, blending into the environment with his long hair blowing in the icy wind. His voiceover begins: “I thought I could escape who I was… but the past never lets go.” The trailer cuts to flashbacks of Bucky’s dark history: his time as the Winter Soldier, missions under HYDRA’s control, and moments of regret as he recalls the lives he took.

The visuals shift between his tormented memories and present-day moments, where Bucky is seen training with the Wakandan Dora Milaje, honing new fighting techniques and learning to harness his inner strength. As the score intensifies, we see King T’Challa’s sister, Shuri (Letitia Wright), working in her lab. She upgrades Bucky’s metal arm with new vibranium tech, enhancing it with powerful Wakandan energy. Shuri’s voice echoes, “The White Wolf must rise to protect Wakanda from what’s coming.” The threat is revealed when an explosion rips through one of Wakanda’s high-tech cities, sending citizens into panic. The camera cuts to the face of a new villain: Anton Vanko, the son of the infamous Whiplash, seeking revenge for his father’s death. Vanko, played by Mads Mikkelsen, stands in front of a massive war machine outfitted with vibranium-imbued weaponry, threatening to tear Wakanda apart unless his demands are met.

His eyes burn with hatred as he snarls: “Your kingdom will fall. And its weapons will be mine.” The action ramps up as Bucky, now fully equipped with new tech and combat skills, leads a small group of Wakandan warriors against Vanko’s forces. Explosive fight scenes show Bucky in intense hand-to-hand combat, his vibranium arm smashing through armored enemies while his tactical mind guides him through the chaos. There are fast cuts of Bucky racing through the jungle on a hoverbike, taking down enemy drones, and fighting Vanko in a brutal one-on-one battle. In the final moments, the trailer teases an emotional moment where Bucky visits T’Challa’s memorial, paying his respects to the late king. As the camera zooms in on Bucky’s determined face, his voiceover declares: “I fight for those who can’t. I fight for the future.”
