Jennifer is a TV and Movie News Editor at ScreenRant. She started her journey in entertainment media in 2022 when she first joined Valnet at CBR before coming to ScreenRant.

Jennifer loves TV, especially science fiction. She also loves late-night talk shows, due to her insomnia. Alien: Earth is definitely one of her favorite shows, and she jumps on any chance she gets to write about it. Even on her days off, she will claim an Alien Earth article if one is available. 

Jimmy Kimmel and Jimmy Fallon are two of her favorite late-night hosts, and Conan O'Brien before he left his show.

Her Alien: Earth coverage for ScreenRant is by far the work that she is most proud of so far.

She was initially a finance and political editor, but her passion for pop culture convinced her to transition into entertainment journalism.

During her off time, she loves to binge-watch cooking shows such as Kitchen Nightmares. Jennifer also loves spending time with her daughter and cherishes every moment of it.

Marvel Studios revealed that Avengers: Doomsday is giving Robert Downey Jr.'s Doctor Doom a new name in the MCU.

Avengers: Doomsday will bring together some of Marvel's most recognizable heroes for a major fight against Doctor Doom. The film serves as a follow-up to 2019's Avengers: Endgame. Anthony and Joe Russo return to direct the film, which was written by Michael Waldron, Stephen McFeely, Chris McKenna, and Erik Sommers. The story will unite the Avengers, New Avengers, Fantastic Four, Wakandans, and the X-Men as they confront a major multiversal crisis.

The Marvel Cinematic Universe's upcoming superhero film Avengers: Doomsday has confirmed a new title for Downey Jr.'s iteration of the villain, Doctor Doom, through officially licensed merchandise. The new update could potentially offer another clue about the character's role in the highly anticipated movie.

New Funko collectibles inspired by Avengers: Doomsday reveal that the character's name is Lord Doom. The new title lines up with Victor von Doom's royal status and connection to the fictional European nation of Latveria. The officially licensed merchandise introducing Downey Jr.'s antagonist under a different name heavily implies that it will come into play in some capacity. However, any further information regarding this change remains to be seen.

The update comes as Marvel continues to promote Downey Jr.'s return to the MCU, this time portraying one of the most recognizable villains in Marvel Comics rather than Tony Stark. The Funko's Avengers: Doomsday figure in question is a part of an exclusive Concept Series collection. The figurine's box is labeled Lord Doom and has a significantly different appearance from the character's traditional design.

Instead of the heavy metallic armor typically associated with Doctor Doom, the collectible shows him wearing a green military-style uniform with gold detailing. His iconic mask remains part of the design, maintaining his classic appearance and keeping him recognizable while adding something new.

Avengers: Doomsday features a massive ensemble cast that includes several actors who will reprise their roles. The star-studded line up consists of Chris Hemsworth (Thor), Chris Evans (Steve Rogers), Anthony Mackie (Captain America), Sebastian Stan (Bucky Barnes), Tom Hiddleston (Loki), Paul Rudd (Scott Lang), Simu Liu (Shang-Chi), Letitia Wright (Shuri), Tenoch Huerta Mejía (Namor), Florence Pugh (Yelena Belova), David Harbour (Alexei Shostakov), Pedro Pascal (Reed Richards, Vanessa Kirby (Sue Storm, Joseph Quinn (Johnny Storm), Ebon Moss-Bachrach (Ben Grimm), Patrick Stewart (Professor X), Ian McKellen (Magneto), Kelsey Grammer (Beast), Alan Cumming (Nightcrawler), Rebecca Romijn (Mystique), and James Marsden (Cyclops).

Avengers: Doomsday will be released in theaters on December 18, 2026.
