When Gotham first hit screens back in 2013, it was strictly a Bruce Wayne and Jim Gordon story. Sure, there would be villains such as Penguin and the Riddler - as well as sidekicks such as Alfred Pennyworth and a young Selina Kyle - but Batman and the Joker were strictly off the table. However, as the series progressed, Warner Brothers calmed on the idea and, by the time it wrapped up earlier this year, the caped crusader himself had made it into the show.
