Doctor Strange in the Multiverse of Madness has done a great job of revealing only what the creators want with each trailer and TV spot. 

But to the surprise of many, its latest TV spot teased at least three members of the recently confirmed Illuminati 

The Illuminati was a collective of incredibly powerful and intelligent heroes in the Marvel Universe of the comics. 

From Reed Richards to Doctor Strange, this team would assess possible threats to Earth, whether they came from the cosmos or the planet.  

Captain Carter, like Steve Rogers, has always been the moral center of her universe. When faced with insurmountable odds, she would still be there to fight, even if it meant she wouldn't survive. 

To her, the safety of all life trumped her own mortality. Because of this, she was chosen by Uatu, The Watcher, to face Infinity Ultron in What If...?. 

There's much that's left to be revealed with Multiverse of Madness' Illuminati. But one aspect that may be more evident than ever is that Captain Carter is a crucial member of the team.  

Whether or not she was chosen for the right or wrong reasons doesn't matter because her character and life have made her a prime choice in any reality.
