The teaser trailer for 2019’s Captain Marvel movie has now dropped, and though there’s not a great deal of detail at this early stage, there are some tantalizing pieces of information in which we can start to put together Carol’s origin.
Like a lot of comic book characters, Captain Marvel has a long and complicated history, and part of the fun of a new movie is finding out what parts of her backstory will be kept, and what will be ditched. There’s an interesting part of the teaser in which we find out that her memories aren’t what they seem to be. Though brief, this gives us a lot of information regarding some specific moments in her comic book life.
“I keep having these memories. I see flashes. I think I had a life here...but I can’t tell if it’s real.” The majority of Carol’s lines in the Captain Marvel teaser concern her past and her recollections of her past. In the comics, those memories -- or lack thereof -- play a pivotal role in the early career of Captain Marvel.
When Carol was the youngest security captain ever to work at NASA, she found herself involved in the adventures of Mar-Vell, the original Captain Marvel, and by association, she gathered some powerful enemies. It was on one of these adventures that she was knocked into a powerful Kree weapon called the Psyche-Magnetron, which altered her on a molecular level, giving her powerful new abilities and altering her DNA, making her essentially half-Kree in the process.
This accident with the Psyche-Magnetron (possibly the device we see in the trailer) caused her to lose her job at NASA, as well as suffer from severe blackouts that would result in her personality switching between Carol Danvers and that of a Kree Warrior. This painful collision of memories was eventually reconciled by Carol, and when she worked through this transition she emerged on the other side as the superhero Ms. Marvel. This experience could be what the Captain Marvel movie is referencing, based on the footage from the trailer, but Carol’s experiences with lost memories don’t, unfortunately, end there.
