Well, for one thing, Peter's life would be very different. He'd be in a darker, more brooding environment. Batman would probably train him even more rigorously. Peter's scientific knowledge could be a great asset to Batman's tech - based crime - fighting. In terms of the Marvel Universe, it would be a big loss. But in the DC Universe, he could become a key figure in Gotham's protection, and perhaps inspire other young heroes in the DC world.
It really depends on personal preference. DC often has darker and more brooding storylines, with iconic characters like Batman. Marvel, on the other hand, is known for its more relatable and humorous heroes like Spider - Man. In the graphic novels, DC might appeal to those who like complex, multi - layered stories, while Marvel could be great for fans of action - packed, fun - filled adventures.
Sure is! Batman has been a staple of DC Comics for a long time. His stories and adventures are part of the DC universe. DC has built a rich and complex world around him.
