One Night In Gotham City Superman and Batman meet each other for the first time. Batman is on the trail of the criminal known as Magpie. He is interrupted in a lead by Superman who regards him as an outlaw. Rather than risk capture, Batman informs Superman that should the latter make any attempts to come near him, a signal will be activated that will trigger a bomb and kill a person somewhere in the city. The two are forced to work together and eventually capture Magpie. In the end, Batman reveals to Superman that the endangered person is Batman himself. Superman departs cautioning Batman against crossing any further lines. Batman admits to himself of a respect for Superman’s innate goodness and wonders if, in a different reality, they could have been friends.
