The MCU's hype machine just went into overdrive. According to Rolling Stone, Marvel's latest Avengers: Doomsday teaser at D23 has triggered a collectibles feeding frenzy, with Black Panther merchandise currently sitting at the number-one bestseller spot on Amazon.

Robert Downey Jr.'s Doctor Doom reveal is positioning him as the franchise's next major threat, and fans are already locking in their pre-orders. Doctor Doom collectible figures, priced at $39.99, are flying off the virtual shelf alongside the Black Panther Marvel Legends set, both dropping Oct. 1, 2026.

The Black Panther momentum arrives as Marvel announced that David Jonsson will take over the Black Panther mantle as T'Challa II in the upcoming Black Panther 3. Yet Letitia Wright's Shuri is also confirmed to appear in Avengers: Doomsday, cementing her role in the MCU's immediate future even as a new Black Panther emerges.

Marvel's merchandising strategy leans into both narratives: the old guard appearing in the universe's biggest crossover while a new Black Panther takes the mantle. Collectors are investing in two timelines of the Black Panther legacy simultaneously.

The collectibles extend beyond action figures. LEGO is releasing two new Doomsday sets, a sprawling 954-piece New Avengers Tower for $109.99 and a 6-minifigure Epic Battle set at $99.99, both shipping Oct. 4, 2026. Marvel is stacking every revenue stream ahead of this crossover event.

For global MCU audiences, especially in India where Marvel collectibles have become status symbols among younger fans, preorder windows fill up fast in major markets. The Black Panther number-one bestseller status suggests limited stock and serious demand.

D23 footage revealed Downey's return as a villain, Fantastic Four and X-Men character appearances, and a multiverse-scale threat. The merchandise has already captured every corner of the Marvel universe for Doomsday.
