The fourth teaser for Avengers: DOOMSDAY is officially playing in theaters — and it may be quietly revealing how the war against Doctor Doom actually begins. With the X-Men teaser now attached to Avatar: Fire and Ash, leaked descriptions and screenshots of Teaser 4 have started circulating online. While no leaked footage is shown here, this video breaks down everything we know about the Fantastic Four, Wakanda, Talokan, and how Marvel is setting up multiple teams across the multiverse. From Shuri, M’Baku, and Namor preparing for battle… to Ben Grimm (The Thing) coordinating with Wakanda… to massive connections with early Avengers: Doomsday plot leaks, this teaser lines up with a multiverse-spanning war similar to Infinity War — but far more interconnected. We also explore: • Why the Fantastic Four are heading to Earth-616 • How Wakanda and Talokan may hold the line against Doom • The rumored Beast, Reed Richards, and Shuri incursion device • Why Marvel’s Doomsday teasers are so minimal and ominous • And why a Loki-focused fifth teaser may be coming next Marvel isn’t showing us Doctor Doom yet — but the countdown has already begun. 👇 Drop your theories in the comments 👍 Like the video if you enjoy Marvel deep dives 🔔 Subscribe for weekly Avengers DOOMSDAY & Secret Wars breakdowns Avengers Doomsday Avengers Doomsday teaser Avengers Doomsday teaser 4 Avengers Doomsday teaser breakdown Avengers Doomsday explained Doctor Doom MCU Doctor Doom Avengers Fantastic Four MCU Fantastic Four Avengers Doomsday Wakanda Avengers Doomsday Namor Avengers Doomsday Shuri Avengers Doomsday M'Baku Avengers Doomsday X-Men Avengers Doomsday Earth 616 MCU Earth 828 MCU Earth 10005 MCU Marvel Doomsday trailer Marvel teaser breakdown MCU multiverse war Marvel Secret Wars setup Avengers multiverse explained Marvel Phase 6 MCU Phase 6 Marvel leaks and rumors Avengers Doomsday plot Avengers Doomsday theory Loki Avengers Doomsday Russo Brothers Avengers Avengers Infinity War comparison Marvel cinematic universe Marvel explained Marvel theories MCU breakdown Comic book movie breakdown
