I’m not the only one. There were, and are, several mattress superheroes out there. Most of them before my time.
You may be surprised to find out how many hours I have spent scouring the tenth page of google looking for these former sleep superheroes. What I found is they’re all following Superman’s lead. The power to leap a tall building in a single bound! Personally, I’m not a huge fan of Superman. He was born great. He is already strong and fast. Those powers came to him by default.
Bruce Wayne, on the other hand, had to achieve greatness! Granted he was born into wealth, but the mechanical ingenuity and martial arts skills are not a result of being born with a silver spoon in his mouth. We do not all come preprogrammed to somersault while kicking a bad guy while simultaneously firing a bat hook to swing up a ledge while throwing a Batarang to catch another bad guy. He had to train hard for years to learn those skills.
