16. Commissioner Gordon
Commissioner James “Jim†Gordon has been by Batman’s side literally since the very beginning. His first appearance, in fact, was as a detective alongside the Dark Knight in the famous Detective Comics #27. He remained a detective for the rest of the pre-Crisis era.
After the Crisis, Gordon was re-introduced in Batman Year One as a Gotham-born detective who had spent over a decade in Chicago before returning to the newly corrupt Gotham. Once there, he worked his way up through the force, rooting out corruption as he did, becoming a Lieutenant and then the Commissioner.
After his daughter was crippled by the Joker, Gordon had a bout of self doubt, but was saved by his new romance with former lover Detective Sarah Essen…who the Joker eventually murdered. Before he could fully recover from that blow, Gordon was shot in the back by an aggrieved criminal, and he took this opportunity to retire from the GCPD.
But he couldn’t stay away for long, and years later returned to the role of Commissioner. And then the New 52 messed with everything.
