User blog comment:Mar-Vell2/Lunella Lafayette Is The Smartest Person In The Marvel Universe??/@comment-16461120-20160803193017

Have you read her book? She's a genius as well, the difference is that Lunella sees the world from a fresh perspective, and fear is a very powerful motivator, allowing her to potentially solve problems that elude those you listed. It's the same reason that Valeria sometimes finds solutions to things that stump Reed.

Also, Banner, Xavier, and very possibly Pym are presently deceased.
