Starting in 1969, writer Dennis O'Neil and artist Neal Adams made a deliberate effort to distance Batman from the campy portrayal of the 1960s TV series and to return the character to his roots as a "grim avenger of the night". O'Neil said his idea was "simply to take it back to where it started. I went to the DC library and read some of the early stories. I tried to get a sense of what Kane and Finger were after."

At age 14, Bruce embarked on a journey that took him to every continent as he sought to learn all the skills he would need to keep his vow. He studied criminology, forensics, and criminal psychology, and learned from manhunters and martial artists, mastering every fighting style. In time, Bruce forged himself into a living weapon to wage war on crime and injustice. On his return to Gotham, Bruce stalked street thugs as a plainclothes vigilante. Beaten by the very people he intended to protect, he barely survived his first night out. As he sat bleeding in his study at Wayne Manor Bruce knew that he had to first strike fear in the hearts of his foes. Just then, a bat crashed through the study window, giving Bruce the inspiration he needed.
In those days it was like, one artist and he had his name over it [the comic strip] — the policy of DC in the comic books was, if you can't write it, obtain other writers, but their names would never appear on the comic book in the finished version. So Bill never asked me for it [the byline] and I never volunteered — I guess my ego at that time. And I felt badly, really, when he [Finger] died.
