Summary
According to a wild newMCUtheory,Captain America: Brave New Worldhas the perfect opportunity to wrap up some of Phase 4’s most annoying unresolved storylines. Marvel Studios' massive increase in content following the conclusion of the Infinity Saga has meant that some storylines and plot threads have gone unaddressed for several years. This has become a more noticeable problem as time has progressed, particularly afterMarvel Studios confirmed a slowdown in output, but one upcoming MCU movie could fix these issues.
Captain America: Brave New Worldis the next movie in Marvel Studios' release schedule, set to premiere on August 07, 2025. Thefirst trailer forCaptain America: Brave New Worldhas revealed a huge new development, as the Phase 5 movie will finally introduce adamantium to the MCU. According to a new theory posed byReddituser AdditionalInitial727,this could form the basis of a game-changing storyline that could explain the formation of two upcoming superhero teams and wrap up many loose endsfrom the MCU’s Phase 4.
MCU’s Phase 4 Left Many Questions Unanswered
Many are still waiting for answers to some of the biggest burning questions from the MCU’s Phase 4. Most notably, however, the mystery of theCelestial Tiamut is set to finally be answeredinCaptain America: Brave New World, which suggests that other storylines could also be addressed in the upcoming movie.Phase 4 introduced the idea of battle between Thor and Hercules, debuted T’Challa’s secret son, Toussaint, and revealed Sharon Carter to be the enigmatic Power Broker, none of which has been paid off.
White Vision’s disappearance at the end ofWandaVisionis set to be addressed in Marvel Studios' upcomingVisionseries. However,there are no answers in sight following Harry Styles' Eros' debut, Doctor Strange growing a third eye, Dane Whitman teasing the Ebony Blade, Arishem stealing the Eternals from Earth, the Ten Rings sending out a beacon, Skaar’s debutand many more. The MCU has become something of a convoluted mess in recent years, butCaptain America: Brave New Worldmight provide the perfect way to wrap up some of these stories.
10 Worst MCU Loose Ends We Need Answers For
While MCU projects often leave cliffhangers to set up future stories, several of these loose ends haven’t yet been revisited by Marvel Studios.
MCU’s Secret Societies Battle Over Tiamut’s Adamantium: Captain America 4 Theory Explained
Adamantium’s debut inCaptain America: Brave New Worldis very exciting, and not only because it teases the introduction of everyone’s favorite clawed mutant, Wolverine. Theories suggest that adamantium could become the new focus of the MCU’s resource race, which was directly hinted at inBlack Panther: Wakanda Forever. However,AdditionalInitial727 posits that it won’t be the governments of the world that squabble over who gets their hands on adamantium, but rather the MCU’s more secret societies.
This theory suggests thatCaptain America: Brave New Worldcould tie up loose ends such as Namor’s threat and M’Baku’s possible promotion to Wakanda’s throne inBlack Panther: Wakanda Forever, Xu Xialing’s takeover of the Ten Rings inShang-Chi and the Legend of the Ten Rings, and New Asgard’s new role inThor: Love and Thunder.A fight between Wakanda, the Ten Rings, Talokan and New Asgard over claims to adamantium could be world-changing for the MCU, and would create some epic moments inBrave New Worldand beyond.
Captain America 4 Theory Explains 2 New MCU Teams Forming
Bringing together the nations of Wakanda, Talokan, New Asgard and the Ten Rings organization in a massive war over adamantium would not only wrap up several loose ends from the MCU’s Phase 4, but could also perfectly explain the formation of two new superhero teams.Captain America: Brave New Worldwill see President Ross urge Sam Wilson to rebuild the currently-inactive Avengers, while the Thunderbolts team will come togetherin their upcoming eponymous movie. These teams could be pivotal in protecting the world during a battle between theMCU’s secret societies.
The New Avengers Line-Up: Predicting Captain America’s Replacement Heroes
The first Captain America: Brave New World footage teased the creation of a new Avengers team, and some heroes are perfect for Sam Wilson’s squad.
Some of the MCU’s most powerful heroes have connections to these nations and organizations, so it would make sense to bring them togetherto try and deal with this possible conflict. Shuri’s Black Panther, Okoye’s Midnight Angel, Shang-Chi, Riri Williams' Ironheart and Thor, just to name a few, could form the foundations of anew Avengers team, while the Thunderbolts could have a darker role in ending the battle. If this theory turns out to be true,Captain America: Brave New Worldcould change the shape of the MCU forever.
