- There are several nods to other adaptions to Batman.
- It's strongly implied that Dick and Barbara have a crush on each other, but they also are too stubborn to admit it to each other.
- Carrie is introduced as Robin during Bruce's prime rather than after him becoming older like The Dark Knight Returns.
- The character of the Executioner was originally from Gotham.
- The character of Marian Drews was originally from Batman: White Knight.
- The show's version of Barbara's mother is strongly influenced by her Gotham counterpart, although being more sympathetic.
- The Joker is portrayed as a blend of Joaquin Phoenix's physique, Heath Ledger's makeup and clothing, Cameron Monaghan and Mark Hamill's personality and Jack Nicholson's voice.
- Harley is also portrayed as a blend of different versions of her, including Jenny Slate's (as a blonde) physique, Margot Robbie's makeup, Super Hero Girls' clothing and Arkham's personality.
- The show's version of the Penguin is similar to Telltale's and Gotham's versions.
- Some villains from the 1960s series are reintroduced and modernized.
