Batman's escapades could be a coping mechanism created by him to deal with the trauma of losing his parents, with others going along with it. Commissioner Gordon is privy to Batman activities and pretends to be surprised; he supports Bruce's vigilante persona in order aid in his recovery. Gordon permits Batman to achieve small triumphs as a way of compensating his past losses, leading to the growth of their partnership and friendship.
According to recent evidence presented in Batman: The Brave And The Bold #9, it's possible that Batman's adventures are simply an act he created to cope with the loss of his parents, with others playing along. Commissioner Gordon is aware of Batman's antics and pretends to be surprised, indulging in Bruce's vigilante fantasy to help him heal. However, the story also suggests that Gordon might have been faking his role all along, merely humoring Batman. So, it's possible that Batman's favorite trick of disappearing mid-sentence is even older than fans think, and that his entire persona might be nothing but theater.
The article discusses how various characters in the Batman universe indulge in Bruce's vigilante fantasy. In "Whatever Happened To The Caped Crusader?" by Neil Gaiman and Andy Kubert, Alfred and his old theater troupe pretend to be villains to perpetuate the charade. Similarly, Gordon in "Nor Is the Batman" acts surprised by Batman's prowess and hands him clues to move the plot forward. However, this does not mean that Gordon is behind Gotham's criminals. Instead, he indulges in Bruce's eccentricities to allow their partnership and friendship to flourish. The article concludes by mentioning that Batman: The Brave And The Bold #9 is available from DC Comics.
