Characters based on appearances in Batman: Arkham Knight.

These are a special subset of the Arkham characters. After the 2.8 update, they are affected by (the Arkham teammate part of) the passives of Harley Quinn/Arkham and Bane/Arkham Origins, and will affect the passive of The Joker/Arkham Origins.

Arkham Knight Catwoman is the only character to specially and more limitedly count the four other characters in this category.
