Post the success of ‘Spider-Man: Brand New Day’, all eyes have now turned to the Russo Brothers’ directorial ‘Avengers: Doomsday’ which is just months away from its theatrical release. Speculation surrounding the Marvel Studios blockbuster has only intensified, with alleged plot leak making their way online. After a social media handle claimed to drop the entire plot of the film, a new post going viral online, claims to reveal more details about the film’s climax, character deaths and the film’s connection to ‘Avengers: Secret Wars’.The unverified leak reportedly outlines the film’s third act, however, it must be noted that none of these plot details have been confirmed by Marvel Studios, or has featured in any promotional material thus far.According to the alleged leak, the film’s climax sees the Avengers and other heroes from the Multiverse, joining forces for an assault on Latveria, where they face-off against Victor von Doom and an army of Doombots. The sequence features several unexpected character pairings, including Ryan Reynolds’ Deadpool fighting alongside Spider-Man and Captain Marvel. The leak also claims that a version of Hulk will face off against Ben Grimm/The Thing. The battle allegedly ends with devastating consequences as the multiverse begins to collapse. Among the most significant claims is that Doom kills Bucky Barnes, with the purported death serving as one of the film’s major emotional moments, and could also be as impactful as the death of Loki in ‘Avengers: Infinity War’.The alleged plot details further claim that Doctor Strange, who is supposedly working alongside Doom, uses magical artefacts and Franklin Richards’ Power Cosmic to help construct Battleworld following the collapse of the multiverse. The reported ending allegedly shows Doom ruling over the newly created realm, with the remains of the Avengers Tower and the Baxter Building, forming part of the fractured world.The leak also claims that Doom resurrects various characters and forces them to serve under his rule. Among his reported enforcers are alternate versions of Thor, and Namor.Another major twist allegedly involves Chris Evans’ Steve Rogers, who is said to become a brainwashed Captain HYDRA, serving as one of his most powerful followers. Buzz about Steve turning a shade grey comes after alleged leaked photos from the sets that show him chained in a cell.The purported leak reportedly ends with reports of Elizabeth Olsen’s Scarlet Witch, resurrecting after the events of ‘Doctor Strange In The Miltiverse of Madness’. She is rumoured to take her place alongside a secret group of surviving Multiversal heroes.Jonathan Hickman’s Secret Wars comic-book storyline is also said to have a major role in this saga, despite there being no official confirmation that these details represent the actual plot.Directed by Joe and Anthony Russo, ‘Avengers: Doomsday’ which releases on December 18, is expected to serve as a bridge toward ‘Avengers: Secret Wars’, which brings the end of the Multiverse saga in 2027. Ahead of the film’s release, the MCU has lined up the rerelease of ‘Avengers: Endgame’, with approximately 4 minutes of additional new footage that will reportedly set the stage for the new films.
