Deadpool in Avengers: Doomsday: Will Ryan Reynolds’ Merc With a Mouth Break the MCU? 💀🗡️🎬

Marvel fans, buckle up — the Avengers are back, Doctor Doom is ready to rewrite destiny, and somewhere in the middle of this multiversal chaos, there’s a big question mark: Deadpool.

With Avengers: Doomsday (2026) shaping up to be the most ambitious Marvel project since Endgame, the internet is buzzing about whether Ryan Reynolds’ Wade Wilson will finally make his grand, foul-mouthed entrance alongside Earth’s Mightiest Heroes.

“Life is an endless series of train wrecks with only brief, commercial-like breaks of happiness.” — Deadpool’s philosophy may never have been more fitting for the apocalyptic stage of the MCU.

🕶️ The Doomsday Lineup: Too Big to Ignore

Directed by Anthony and Joe Russo, written by Michael Waldron (Loki) and Stephen McFeely (Endgame), the film isn’t just an Avengers story — it’s a battle royale of Marvel legacies.

• The Avengers: Thor (Chris Hemsworth), Captain America (Anthony Mackie), Ant-Man (Paul Rudd)

• The New Avengers: Yelena Belova, U.S. Agent, Ghost, and more

• The Fantastic Four: Reed Richards (Pedro Pascal), Sue Storm (Vanessa Kirby), Human Torch (Joseph Quinn), The Thing (Ebon Moss-Bachrach)

• The X-Men: Professor X, Magneto, Wolverine’s comrades — even Gambit (Channing Tatum)

• Doctor Doom: Played by Robert Downey Jr. in a reality-bending twist

And somewhere between this cosmic clash stands the wildcard — Deadpool.

💀 Deadpool’s Multiverse Wild Card Entry

Rumors swirl that Ryan Reynolds has already filmed scenes tying Deadpool 3 directly into Doomsday. Marvel hasn’t confirmed, but fans suspect Wade Wilson might stumble through a multiverse portal — maybe dragging Hugh Jackman’s Wolverine along for a few fourth-wall-breaking jabs at Disney.

If true, Deadpool could:

• Mock the Endgame portal scene (“On your left? More like on your meta.”)

• Roast Doctor Doom (and possibly call him “Iron Doom Jr.” because of RDJ)

• Deliver comic relief when the Avengers face their darkest hour

Imagine Deadpool walking into the battlefield saying:"Wait, this isn’t my movie… oh, wait, it is now."

⚔️ Doom vs. Deadpool: A Battle of Tones

The Russos have promised a darker, more operatic Avengers film — closer to Infinity War than Endgame. Doctor Doom, a character with gravitas and Shakespearean menace, is set to become the MCU’s next god-tier villain.

Enter Deadpool: sarcastic, chaotic, and completely unwilling to respect the tone. His very presence could shatter the seriousness of Doomsday — and that might be exactly what Marvel wants.

🎟️ Why Deadpool Matters for Doomsday

1. Fan Service Overdrive – Ever since Disney acquired Fox, fans have been waiting for Deadpool to meet the Avengers and X-Men in the same frame.

2. Comic Accuracy – Deadpool has fought, teamed up with, and annoyed literally everyone in Marvel lore.

3. Secret Wars Setup – If Wade can break through realities, he might be key to Secret Wars (2027), where universes collide.

📅 Release & Streaming

Avengers: Doomsday smashes into theaters worldwide on December 18, 2026. Following Disney’s model, the film will eventually stream on Disney+, but not before it aims to conquer box office records like Endgame.

🎬 Final Thoughts: Deadpool, The Chaotic Glue of Doomsday

If Ryan Reynolds is in this film — even for five minutes — he could end up stealing the show. Imagine Deadpool roasting Thor’s cape, poking fun at multiverse timelines, or breaking the fourth wall during Doom’s dramatic monologue.

Because when the universe is ending, only one thing’s certain: Deadpool’s going to have the last laugh.
