'Avengers: Doomsday' Trailer 4 Leaked: Fans shocked by Black Panther & Fantastic Four crossover, full deets inside

'Avengers: Doomsday' Trailer: Marvel Studios’ promotional plans for Avengers: Doomsday have hit a hiccup as the fourth trailer leaked online just hours after the release of the third official teaser. Fans were treated to a surprising crossover between Black Panther and the Fantastic Four, rather than the previously speculated Robert Downey Jr. as Doctor Doom facing the Council of Kangs.

Leaked Trailer Highlights: Shuri, Namor, and Wakanda

The leaked one-minute clip begins with Letitia Wright reprising her role as Shuri, now the Black Panther, delivering a poignant monologue: "I’ve lost everyone that matters to me. A king has his duties. To prepare our people… for the afterlife. I have mine."

Tenoch Huerta appears as Namor, along with the Talokanil, the underwater civilisation, now depicted in a desert-like kingdom above ground. Winston Duke returns as M’Baku, joined by the Dora Milaje, and provides some comic relief with a witty exchange with Ebon Moss-Bachrach’s Ben Grimm, aka The Thing: "King M’Baku of Wakanda.", "Ben… Uh, Yancy Street. Between Broome and Grand."


The trailer concludes with the title card, confirming: "The Wakandans and the Fantastic Four will return in Avengers: Doomsday."

Leaked Clips Taken Down

Following the leak, many social media posts of the trailer have been removed, sparking speculation that this was not another AI-generated fake but an actual studio clip accidentally leaked.
