Mister Fandango
Fleet Captain
I'm pretty sure that's far more prevalent in the comics than in TV or pretty much any other medium. Just in the Marvel universe alone you have characters like Reed Richards, Hank Pym, Doctor Doom, Beast, Mr. Sinister, Bruce Banner, Tony Stark, and even friggin' Peter Parker, all off the top of my head.Please, no. I am so sick of the cliched TV assumption that any given scientist can be an expert in every branch of science at once.
