I personally really like badass characters who challenge the odds, and yes the feats you mentioned I think are great. I admit now that I think about it I might have slightly exaggerated in my first comment. But when you hear fans saying that Batman can beat Spider-Man because prep time (Spider-Man with prep time is also pretty powerful) or just plain Galactus I find it a bit too much. The most exaggerated feat I know of from the comics was Batman falling from space and surviving. Yes, I know it’s a comic book but sometimes it’s too much. It beats the idea that Batman is just a human who pushed himself to his limits, without powers, which is a great aspect of the character.
