Seeing as there are no new comics for a while and quarantine has got me bored, I decided to make this a thread.
To begin, many writers have failed Sue in not giving her a particular field of expertise of wants and desires outside of the family like her male teammates do. It is sadly common with female heroes from the silver age. I believe that should change. As she will almost definitely have a career field in her MCU debut, 616 Sue should have had one decades ago.
The filed that I believe suits her and her dynamic as a part of the Fantastic Four is being an archaeologist. But not just an archaeologist, but a Xeno-archaeologist which is a mostly fictional field as it involves alien cultures. This way it would encompass the more cosmic elements associated with the Fantastic Four and add an interesting spin to the field.
Sue being an archaeologist fits the adventure aspect of her team and gives her more agency both in and out of it.
Instead of it always being Reed dictating where the team goes for an adventure, Sue could find something on a dig or want to investigate a particular place. When you add the extra-terrestrial aspect to it, there are tons of interesting avenues to go with it.
It's also a career that doesn't many Marvel heroes occupying it so she could truly make it her own that people associate with her. Which can't be said for her recent adventure as a spy which has many heroes associated with it. When you ask someone about heroes who are spies; Black Widow, Spider-Woman, Hawkeye, and Mockingbird would all spring to mind way before Sue.
What I enjoy about the possibility is that Marvel already did it. In Fantastic Four: The End, a story that took place in a alt-future, Sue is an archaeologist and is on a cool Tomb Raider/Indiana Jones-like adventure. The prospect is already there and I think Marvel should do it.
For Reed it's often about the science, but for Sue it's often about the people. The above shows how being an archaeologist could show that, with her being interested in the culture and what they could learn from it.
