As an Industrial design major, myself, I've always been fascinated over Iron Man, (Comics, Cartoons, movies) and Terminator. Iron man because an exo armored suit that enhances your physical qualities isn't impossible, and very likely to be used as a weapon, like all inventions.
Before Iron Man, these used to be the reasons why I liked Robocop so much, although Iron Man is a more realistic scenario.
Terminator because, opposite to Iron Man, it has an Endo Skeleton with superior qualities than human. These, someday, will be the future of medical science and high-tech prosthesis, if not weapons, too.
When it comes to Industrial design, we study the subject the product we are designing for will use. People, most of the time. Then, we design the product to aid and enrich the subject's life. When you end up deciding which movie or book's tech you will focus on, make sure it is one that affects real people, directly. Something like designing Superman's unbreakable toothbrush could be an interesting "what if" project, but not something useful in real life, with everyday people.
This is the main reason why I like Nolan's Batman better than any of the other Batman films: Bruce Wayne, a human with not super-powers, is a high-tech urban soldier suited-up with arsenal developed for the US army. Everything in his suit has a function. I'm not too crazy over gliding with a cape, although it seems they are, indeed, developing this product, but his armor is something soldiers could benefit from.
There is a TV show that studies Super-Heroes powers and gear with realistic analysis. They have a few of these on youtube. Here's one: Batman Tech:
