Marvel Zombies already came out: it was released on Disney+ on September 24, 2025, as a four-episode animated mini‑series set in the MCU multiverse.

Quick Scoop

✅ Release date & where to watch

  • Premiered on: September 24, 2025.
  • Format: Four‑episode animated event (mini‑series), not a full-length movie.
  • Platform: Disney+, under the Marvel Animation banner.

If you search for Marvel Zombies (2025) on Disney+, you should find all four episodes available to stream as a completed season.

What kind of show is it?

  • It’s an animated spin‑off of the What If…? episode “What If… Zombies?!” and continues that zombie‑plague concept in the MCU multiverse.
  • It dropped as part of Marvel’s Phase Six slate, positioned as a darker, horror‑flavored side project alongside other Marvel Animation titles.

How it released (binge vs weekly)

  • The season consists of four episodes; each is roughly around standard half‑hour animated length.
  • Official listings and coverage describe it as a four‑part event that arrived together on September 24, 2025, so it’s now fully bingeable rather than a long weekly rollout.

Why people were confused about the date

  • Earlier plans had it premiering October 3, 2025, as a Halloween‑season drop, and even before that it was once expected for 2024, which led to a lot of shifting rumors and forum chatter.
  • It was ultimately moved up to September 24, 2025, partly to avoid clashing with Agatha All Along and to spread out Marvel’s spooky‑season content.

TL;DR: If you’re wondering “when is Marvel Zombies coming out?” —it’s already out. All four episodes of Marvel Zombies have been streaming on Disney+ since September 24, 2025.
