It's an annoying argument I get from real cynic cocksuckers;
Me: I looooooooove Batman.
Immature dink out of NOWHERE: HOW CAN BATMAN BEAT SUPERMAN OR GOKU IT'S IMPOSSIBLE.
Believe it or not, I was reflecting back on several other dozens of people when I used "dink".
Batman's ORIGIN had him spend maybe twenty years developing and excelling in a wide array of skills, gave him a COOL grim motif, with a badass remorseless vengeance. In 1940 they made him, in a very nietzschean way, superman. And about beating Superman, his strength is contingent on the sun and he's weak against magic and kryponite. He ain't so bad. As for Aquaman, he can't stay on land very long. His strength is constantly fleeting from the moment he leaves the ocean.
The thing is, villains constantly trump heroes (if only for a bit) and Batman has no qualms operating similarly, but without hubris. That's why crazy Batman fans always clamor about "prep time"; well, that and DKR.
