Batman’s origin story is an absolute tragedy. It features him swearing vengeance against criminals after witnessing the murder of his parents as a child. He trains himself, develops his vigilante persona, and monitors the streets of his home, Gotham, at night, lurking in the dark until a case needs his intervention. Superman/Kal-El, on the other hand, was born on an alien planet called Krypton. His parents send him to Earth to safeguard his life moments before a cataclysmic event wipes out his entire planet. His ship lands in the American countryside near Smallville, which is where Superman is eventually raised. Both origin stories have been told several times and in different forms — but Bruce Timm, in an interview with Comic Book Resources last year, said he believes Superman has “the best origin story.”
Timm compared the two superheroes, explaining how Batman’s origin is more of an “incident,” suggesting Superman’s is relatively rich in details, and the massive scale of it allows for live-action coverage. Since Superman’s origin has a sequence of events to catch up with, Timm, along with his team, was able to illustrate it through three whole episodes, unlike Batman’s, which concluded in minutes.
