>All the characters listed above will not appear until the final act.

>Somehow Wanda's horrific actions have affected the timelines of the other parallel universes, resulting in some living creatures and most humans being trapped in some sort of "Void" location, similar to the location in the Loki series.

>Doctor Strange ends up trapped too, as do most of the characters, especially those we know from other projects.

>The final battle will take place in this Void, think of it as the final battle in Avengers Endgame, but with characters from the other universes.

>They'll have to fight the Shuma-Gorath and his evil army of demonic beings, which is destined to wipe them all off the face of the earth.

>The void is full of cities and skyscrapers, which were also taken from other worlds just like in "Loki."

>Doctor Strange tries to assemble his own version of the Avengers to fight.

>Some of the X-Men come together, such as Ian McKellen as Magneto, Halle Berry as Storm, Hugh Jackman as Wolverine and James Marsden as Cyclops.

>Eric Bana reprises his role as Bruce Banner, who can no longer transform into the Hulk after the events of Hulk (2003).

>Edward Norton transforms into his 2008 version of the Hulk and joins the battle.

>Nicolas Cage appears as Johnny Blaze and initially refuses to help, but then transforms into Ghost Rider and joins the fight.

>The Ghost Rider will be too powerful and will steal the show for most of the fans, he also mentions Mephisto.

>Tobey Maguire's Spider-Man will also have his moment, the actor unfortunately will not be seen, but his voice will be present, mostly a stunt double and CGI.

>Spider-Man doesn't have much involvement in the fights, as he's just trying to protect other defenseless citizens in the Void.

>Hugh Jackman's Wolverine also has a moment where he goes on a rampage, as in the scene in the woods from "Logan."

>There are other interesting cameos during the battle.

Wanda is the main villain

Strange Supreme is just a cameo and has less screen time than the lIlluminati

Illuminati is from a different universe than the MCU. Consists of Monica Rambeau Captain Marvel, Charles Xavier, Reed Richards, Captain Carter from What if, Balder, Sorcerer Supreme Mordo, and Tom Cruise Iron Man

Bruce Campbell is Doctor Druid

Wanda is corrupted by the Darkhold and is trying to find her kids from Wandavision. She can only astral project to other universes and needs America Chavez to get to them.

At Christine Palmer's wedding, the city starts getting destoryed by Gargantos, a sort of Shuma-Gorath clone. It's not him but it's an offshoot sort of like Starro. He is summoned by Wanda to get Chavez. This is where Strange meets Chavez.

The scene from the teaser where Strange asks for help from Wanda comes after this scene. He later realizes she is the one summoning demons and they have a fight.

After the Strange and Wanda bout, she goes to Kamar Taj and destroys it trying to find Chavez.

Using Chavez' powers, Strange and her travel to different universes to escape. They eventually find a reality with sorcerer supreme Mordo. He ends up bringing them to the Illuminati for fucking with the multiverse.

The Ultron bots are under the Iron Man variant's control. They bring Strange before the Illuminati and then imprison them. He tries to tell them about Wanda but they don't listen.

The scene of Wanda meditating in the teaser is when she uses the Darkhold to take control of that universe's Wanda who is basically a housewife and has Billy and Tommy. They are the same age as in Wandavision.

Wanda kills some of the Illuminati upon finding them. Xavier and her have a huge battle where he tries to separate this Wanda from MCU Wanda which doesn't work. He then tries to reason with MCU Wanda and he realizes that the Darkhold is basically controlling her. Think of the symbiote corrupting Spider Man but times ten. She snaps his neck. This scene is super violent and will probably get cut down as test audiences didn't get why Wanda was being so evil. There is pre vis with housewife Wanda covered in blood. She also has dark hair like in Age of Ultron.

Wanda finally finds her kids in the universe but they are terrified of her. The possession is corrupting this Wanda's body and she looks like a zombie. She does the same thing from Wandavision here but to the entire multiverse instead of just Westview. At the same time, Strange and Chavez get back to the MCU but the universe is basically falling apart like in the doctor strange episode of what if. There is a shot of this in the teaser.

Wanda's hex brought her kids into the MCU but they are teenagers. This is to set up young avengers which is confirmed to be happening with Kate Bishop, Eli Bradley, Teddy Altman, Billy and Tommy, and Scott Lang's daughter. The YA story starts in Ant-man 3 with Cassie Lang and Iron Lad.

This leads us into the third act. The only leaks of this are that Loki and Sylvie appear here. They were originally supposed to appear but covid fucked up the schedule. Last round of reshoots was to insert them and possibly Kang.
