Robert Downey Jr. has offered Marvel fans a fresh look at the highly anticipated film Avengers: Doomsday, reigniting excitement for what is expected to be one of the most significant Marvel events to date. The actor posted a new image on Instagram ahead of the film’s release, once again placing the focus on his intriguing role change and fueling speculation about his involvement as both Doctor Doom and the beloved Iron Man, reinforcing the ongoing conversations around Robert Downey Jr. Avengers Doomsday.
Downey Jr., who was integral to the Marvel Cinematic Universe (MCU) as Iron Man for over a decade, stunned fans by returning to the franchise to portray Victor von Doom, also known as Doctor Doom. Since this casting decision was revealed, fans have been theorizing not only about how Tony Stark could return, but also how Doctor Doom and Iron Man might have intertwined connections in this upcoming film. The mystery remains at the heart of fan discussions as new content drops.
The image shared by Downey Jr. features stylized comic book artwork showcasing only the shoulders and hands of Doctor Doom and Iron Man. The visual is themed for Thanksgiving, capturing both characters breaking a turkey wishbone—a nod to the traditional holiday ritual for good luck. This playful, yet symbolic tease adds fuel to the ongoing fan speculation about the storyline and the dynamic between these two iconic Marvel characters.

The timing of this reveal is notable, as Marvel has kept Avengers: Doomsday shrouded in secrecy. Unlike past entries in the Multiverse Saga, few materials, such as set photos or videos, have surfaced online, and the studio has neither released a trailer nor disclosed key plot details. Currently, the confirmed cast, led by Downey Jr., is the main information that fans have to rely on, leaving much to the imagination.
This secrecy will soon change. Collider has reported that the first trailer for Avengers: Doomsday will premiere on December 19 and is scheduled to appear before theatrical screenings of Avatar: Fire and Ash. Given the remarkable success of the Avatar series, which has grossed over $2 billion with each entry, this partnership is poised to maximize the trailer’s exposure and reach a massive audience.
Downey Jr. has a history of engaging fans with creative teases related to Doctor Doom on social media. Earlier this year, he posted an image of the DOOM #1 comic alongside items he called “Doom workstation essentials.” For various holidays, he has also shared themed content: a Doctor Doom mask filled with chocolates for Valentine’s Day, and a humorous behind-the-scenes look at his wife, Susan Downey, dressed as Sue Storm from the Fantastic Four, with her mother, Rosie Levin, knitting a Doctor Doom costume for Mother’s Day. These light-hearted posts have become a means for Downey Jr. to keep anticipation alive and connect with the fanbase in between official updates.
