Ryan O'Rourke is a Senior News Writer at Collider with a specific interest in all things adult animation, video game adaptations, and the work of Mike Flanagan. He is also an experienced baseball writer with over six years of articles between multiple outlets, most notably FanSided's CubbiesCrib. Whether it's taking in a baseball game, a new season of Futurama or Castlevania: Nocturne, or playing the latest From Software title, he is always finding ways to show his fandom.

Between The IV Leader at Illinois Valley Community College and The Pegasus at Eureka, he spent the majority of his college career publishing articles on everything from politics to campus happenings and, of course, entertainment for the student body. Those principles he learned covering the 2020 election, Palestine, and so much more are brought here to Collider, where he has gleefully written on everything from the SAG-AFTRA and WGA strikes to Nathan Lane baby-birding sewer boys.

Marvel created a ton of questions about its next big crossover event when the first teasers for Avengers: Doomsday rolled out back in December and confirmed Chris Evans' return to the MCU. The franchise has since passed the shield to Anthony Mackie's Sam Wilson, who even got his own movie last year in Captain America: Brave New World, while Steve Rogers got to live the life he missed out on with Peggy Carter. Making matters more curious is the shot showing the former Sentinel of Liberty holding a child in his hands. This won't be a brief stay for the seasoned Avenger, as Evans himself has confirmed he'll be in the sequel, Avengers: Secret Wars, next year to some degree, but his successor's fate has been a bit more up in the air.

Mackie, for his part, has been a bit more ominous in his teasing. Doomsday will pit teams of superheroes, from the New Avengers to The Fantastic Four, the Wakandans, the old 20th Century Fox X-Men, and other assorted figures against Robert Downey Jr.'s Doctor Doom, who, as the trailer shows, may be an even bigger threat than Thanos. All signs are pointing to a much darker MCU outing than usual, a feeling further driven home by Mackie assuring that "everyone is expendable" in Anthony and Joe Russo's latest movie, which he says will end on an impactful cliffhanger. Does that include the former Falcon himself, though?

Evidently not. During a conversation with Deadline about his return to play Macbeth on Broadway next year, the star confirmed that he'll be back for Secret Wars shortly after he wraps his time playing Shakespeare's legendary villain. "So once I finish on Broadway, I’ll go to finish up all the Avengers stuff for Secret Wars," he said. That should ensure Sam's safety through the encounter with Doom, at least, though what lies afterward for him remains up in the air. While Mackie will have to suit back up next year to finalize his time in the crossover, the Russos are expected to get started on the production even sooner, given how massive an undertaking it will be and how critical it is to the MCU's future.
