Alleged Deadpool Prop From ‘Avengers: Doomsday’ Sparks Fresh Speculation Over Auction Listing

Marvel Studios has kept its cards close to the chest when it comes to ‘Avengers: Doomsday’s‘ full roster, but that hasn’t stopped fans from combing through every scrap of information for clues about who might show up. With a cast already stretching across the Avengers, X-Men and Fantastic Four, one glaring absence has fueled months of speculation.

Ryan Reynolds’ Deadpool has notably been missing from every official cast confirmation for the film so far, despite the character’s established presence in the wider MCU following ‘Deadpool & Wolverine.’ That silence hasn’t stopped fans from wondering whether the Merc with a Mouth might still make a surprise appearance in the sprawling crossover.

Now a fresh piece of evidence has surfaced that’s reignited that debate. An alleged Deadpool costume prop tied to ‘Avengers: Doomsday’ has gone up for auction online, listed by seller PROPDOMAIN on the collectibles site iCollector as a prototype suit fabric panel connected to the film.

The listing itself is careful not to overstate the connection. “It is still unsure if DEADPOOL is in DOOMSDAY, but this is a solid clue!” the auction description reads, openly acknowledging that the item’s link to the movie remains unverified.

Despite the uncertainty, interest in the item has grown quickly. Bidding for the Deadpool panel started at just $10 and has already climbed to $95, with the piece carrying an estimated value between $300 and $400 once the live online auction officially begins on October 3.

Deadpool isn’t the only Marvel character connected to the sale. A second lot described as a large prototype suit fabric panel tied to Magneto has also appeared in the same auction, carrying an identical estimated value and starting bid, currently sitting at $40. Both listings distinguish themselves largely through character-specific descriptions rather than any confirmed production paperwork.

Collectors interested in inspecting either item in person can reportedly do so by appointment at the auction house’s location in Reseda, California, ahead of the October 3 sale date. Neither listing offers concrete evidence tying the fabric panels directly to confirmed costume production for ‘Doomsday,’ meaning both should be treated as unverified until Marvel says otherwise.

He used to be different.

This isn’t the only Marvel-related item to surface through auction listings recently. The same auction house previously listed a scrapped black suit reportedly tied to ‘Spider-Man: Brand New Day,’ which similarly generated speculation about unconfirmed costume designs before officially being treated as an unverified claim.

That pattern suggests prop houses and auction listings have increasingly become an unofficial, if unreliable, source of pre-release Marvel speculation, filling gaps left by the studio’s traditionally tight-lipped marketing approach. Whether any of these leaked items genuinely originated from active productions or are simply prototype pieces mislabeled for auction interest remains an open question.

With ‘Avengers: Doomsday’ still confirming cast members as recently as this week, according to comments from co-director Anthony Russo, there’s clearly still room for surprises before the film’s December 18 release. Whether Deadpool ultimately factors into the story or this listing turns out to be nothing more than a coincidence, fans will likely keep dissecting every fresh clue until the film finally hits theaters.
