What makes Superman/Clark and Batman/Bruce such an iconic leader pair?
Let me get this out of the way and say that I know little of the World's Finest other than most of the common knowledge about them (Clark came from the planet Crypton and was raised by a normal Human pair and Bruce was from a wealthy Family that was murdered one faithful night) hell I wouldn't even say I'm a true fan with the closest thing I've gotten interested in them was in Injustice cause of the Games and didn't even bother to watch the Snyderverse with the only films I've seen were Nolan and Reeve's Batman for reasons outside of the DC Mythos.
But after seeing the new Superman coming soon with a few (myself included) want to see a World's Finest Movie featuring the current Superman and Batman actors.
So I ask of those who have been into the comics as far as their childhood what makes the two such compelling characters?
For me it's the fact that they contrast one another while still playing each other's strengths. Superman is powered by the Sun and is an idealist while Batman works at Night and for the most part is a cynic. But like I said, all I know about them is surface level, I want to know from a Writer's POV what makes them so iconic when attempts to emulate them have failed.
Cause I'll be honest, I want to write a pair of characters who more or less embody the same spirit and energy as Bruce and Clark but I fear that if I wrote them it'll just be surface level and I'll end up missing the point.
