Following Gotham's success in defeating Dorrance's forces and rejoining the mainland Oswald was given a new eye, (one that required a monocle to see properly), along with a new top hat. He would wear these two items after being released from Blackgate Penitentiary after serving a ten year sentence.
- The monocle is a significant item worn by The Penguin throughout other mediums in the DC Universe.
- Oswald's father Elijah Van Dahl once used a monocle to see the fabric on one of his italian suits in the episode "Wrath of the Villains: Prisoners".
- Penguin's monocle was previously foreshadowed in the episode "A Dark Knight: A Beautiful Darkness". During his sentence at Arkham Asylum, a crescent-shaped wound was inflicted on Oswald's face right underneath his right eye, which looked visually similar to the monocle he would later wear on the same eye.
