Have you heard about the new T.V show Gotham?
Well if you haven't heard about it then here's the deal: the main character of this show is Commissioner Gordon, but when he is young and when he is only a Detective. We also see other characters before we know who they are and we see them while they are still young. while we don't know any of the characters ages, the actor who plays 'Bruce Wayne' is aged 13 so I think that is a rough estimate as too how old the characters are. The T.V show also takes place during the event of Bruce's parents murder.
Now all the official confirmed characters are: Detective Gordon, Bruce Wayne, Selena Kyle (Cat woman), Poison Ivy, Penguin, Riddler, Alfred and Harvey Bullock (Detective Gordan's Mentor/Partner. Now remember that all these characters are young and it takes place before the characters we know them as.
