Sometimes, it's the little things that matter. This is where we acknowledge them.
To begin:
I pointed this out in the hero-exclusive villain thread on why I often have an easier time getting into Marvel than DC, and felt it'd make a good starting point for such a topic. I for one like the fact it's rare to encounter a hero in Marvel who can fly "just because". This stems from the early days, as Stan Lee hated how so many heroes from DC could fly for no reason, and set out to have every character have some kind of unique way of traversal. For the most part, this philosophy stays true today. It really does help to make each character feel unique, just by the way they get around. Some hold onto something like a magical hammer, use jet propulsion, sling on a web, have a suit of armor with thrusters, ride on an object, glide as an extension of their abilities, leap great distances, use a wingsuit, have wings, wear a magical artifact that enables them levitation, surround themselves with energy, or make clever use of shapeshifting. Really, it's a small element that helps each hero feel distinct. In DC, I feel like there are way too many characters who have an innate ability to fly, that makes so many of them feel the same when they traverse.
Anyways, what about you guys? What are the little things about Marvel that you appreciate?
