The magical realm of Kamar-Taj seems under attack from a dark force in the trailer. A black cloud seems to be ripping the Temple-Home of Strange and sadly the battle doesn't go in favor of the sorcerers as explosions rip through the scenes. Another magical realm follows the fate of Asguard's Destruction.
The Kid With The Star Portals

Illuminati & The Professor's X-Men Force

Ha!...Gotcha Tom Cruise
A glowing human figure flies through a kaleidoscopic plane of reality. Some might suspect that this figure is Captain Marvel or its variant but on a closer look the suit resembles to that of Tom Cruise's Superior Iron Man, if its tru than this is going to be the biggest most badass Money Shot Cameo ever in any MCU movie.
