One trope that's become really annoying is the "Omnidisciplinary Scientist". Because they're "smart", they're well-versed in pretty much everything. Comics have never been accused of being realistic, and there really are people who seemingly specialize in everything, but it's still pretty jarring. Marvel's a bit better with this now, but it's still bad.
If each genius or scientist in Marvel had one (or two) fields that they specialized in, what would they be?
Reed Richards: Astrophysics
Tony Stark: Robotics
Hank Pym: Particle physics
Hank McCoy: Genetics
Peter Parker: Materials science
T'Challa: Anthropology
Feel free to add anyone else.
