After a new supervillain called Mr. Bloom apparently killed Gordon and took over Gotham, Bruce learnt about his life as Batman and, after talking to a stranger, returned to the Batcave for the first time since his final encounter with Joker. However, unable to recover the skills required to fight Bloom and his underlings, he decided to use an experimental machine that would upload his memories and skills into a body, but at the cost of his new life. With help from Alfred and Julie (who had discovered the truth long ago), Bruce went through with the procedure and returned to Gotham as Batman. With help from Gordon and a street gang modeled after Robin, he was able to defeat Bloom and save the city once again.
Batman is often treated as a vigilante by other characters in his stories. Frank Miller views the character as "a dionysian figure, a force for anarchy that imposes an individual order". Dressed as a bat, Batman deliberately cultivates a frightening persona in order to aid him in crime-fighting, a fear that originates from the criminals' own guilty conscience. Miller is often credited with reintroducing anti-heroic traits into Batman's characterization, such as his brooding personality, willingness to use violence and torture, and increasingly alienated behavior. Batman, shortly a year after his debut and the introduction of Robin, was changed in 1940 after DC editor Whitney Ellsworth felt the character would be tainted by his lethal methods and DC established their own ethical code, subsequently he was retconned as having a stringent moral code. Miller's Batman was closer to the original pre-Robin version, who was willing to kill criminals if necessary.
