WandaVision proved Wanda Maximoff is one of the Marvel Cinematic Universe's strongest beings, and her power could lead to the destruction of the multiverse. Elizabeth Olsen's MCU hero has gradually become more powerful as her story has continued. After nearly defeating Thanos by herself, WandaVision showed her truly become the Scarlet Witch. This came after altering reality to the point where she controlled all of Westview.

Wanda officially becoming Scarlet Witch is a moment Marvel fans have been waiting to see for years, but WandaVision also included another tease of how powerful and important she is. Episode 7's fake commercial teased the existence of Nexus Beings in the MCU. Each universe has its own Nexus Being who can draw immense power from the multiverse. WandaVision sets up the potential for Scarlet Witch to be a Nexus Being in the main MCU timeline. But with the show's ending also teasing a potentially dark path ahead as she tries to understand her abilities, Scarlet Witch could destroy the multiverse instead.

If Scarlet Witch is a Nexus Being in the MCU, her ties to the multiverse could be how she is so powerful. This has proven to be both a blessing and a curse already for Wanda, as she's hurt and helped people with these abilities. Now that she is studying the Darkhold (potentially at Wundagore Mountain), there is the potential that the evil influence of Chthon could affect Wanda. It is possible Chthon will possess Scarlet Witch and use her powers to fracture the multiverse, allowing him to regain power over multiple universes instead of a single one.

Wandavision How scarlet witch could end the multiverse

The destruction of the multiverse could actually be what Doctor Strange in the Multiverse of Madness is really about. Marvel Studios already confirmed Scarlet Witch has a significant role in the movie. While many hope that is because Doctor Strange will mentor the young witch, it is just as likely that the future Sorcerer Supreme will be tasked with fighting Scarlet Witch instead. After all, Doctor Strange 2's title indicates that the multiverse will be in chaos during the movie. We do not yet know why that is, but it stands to reason that Scarlet Witch has something to do with it - especially since WandaVision was said to set up the movie's events.

Scarlet Witch destroying the multiverse after WandaVision opens the door for the MCU to go in several different exciting directions. Many had hoped the Disney+ series would directly bring mutants to the shared universe, but a shattered multiverse down the road could be how it happens. Perhaps this even provides a narrative way for Ryan Reynolds' Deadpool (and his supporting cast) to join the MCU. The multiverse collapsing could also provide a path for Sony and Marvel to continue sharing Tom Holland's Spider-Man, either by having him constantly go between universes, join the Sony universe exclusively for a few years, or fold Venom and other titles into the MCU.
