Gotham Knights was cancelled after just one season, though the odds were always stacked against The CW series. For starters, while DC Comics fans were initially excited about a show revolving around Batman's sidekicks, it featuring a newly created lead and no costumes was an immediate turn-off.
Then, there are the behind-the-scenes changes at the network which saw them cut a huge number of scripted TV shows (not to mention the DCU reboot that looks set to make all future programming part of the same shared world).
Throw in so-so ratings, and Superman & Lois being saved in preference of Gotham Knights was no great shock.
Still, the series at least tried going out on a high by finally throwing Two-Face into the mix during its final episode. After a heart-to-heart with the daughter he never knew he had, Duela, Harvey gives in to his identity dysmorphia in an effort to use that side of his personality to help save them from an explosion.
However, the evil Harvey has some sinister ideas of his own, and when The Court of Owls' Rebecca March shows up and gets into an altercation with him, she hurls a beaker of acid at the DA's face.
With that, Two-Face is born!
The design is surprisingly gory and, had the show continued, we'd have no doubt spent a lot more time getting to know the villain. The episode also ends with Turner Hayes being trained by Batman's mentor Henri Ducard (Charles Mesure), presumably to set the stage for him to become the next Dark Knight.
