* BillingDisplacement: Circe, the mentor for mystical villains, is replaced on the box art by Catwoman.
* TheOtherDarrin:
** When the game first started, Creator/ArleenSorkin had reprised her role as Harley Quinn. However, when creating new content, Arleen wasn't doing the voice anymore. Instead, they went for Jen Brown (Pyrrha Nikos of ''WebAnimation/{{RWBY}}'', Agent Carolina of ''WebAnimation/RedVsBlue'')
** Creator/GeorgeNewbern and Creator/SusanEisenberg eventually replaced Creator/AdamBaldwin and Creator/GinaTorres in the respective roles of Superman and Wonder Woman.
* RoleReprise:
** From the Franchise/DCAnimatedUniverse: Creator/KevinConroy as Batman, Creator/CoreyBurton as Brainiac, Creator/MarkHamill as the Joker, Creator/ArleenSorkin as Harley Quinn before the recast, and after being recasted, Creator/GeorgeNewbern as Superman, and Creator/SusanEisenberg as Wonder Woman.
** From ''WesternAnimation/SupermanDoomsday'': Creator/AdamBaldwin as Superman himself before the recast and Creator/JamesMarsters as Lex Luthor.
* WhatCouldHaveBeen: There's a concept for a Sinestro Corps-based Iconic Battlesuit "[[http://dcuniverseonline.wikia.com/wiki/File:SinestrosMight_WEB.jpg Sinestro's Might]]. But with the first DLC (''Fight for the Light'') it is now the style set Sector Incendiary.
** Also, the Flash in the game was originally intended to be Wally West (And likewise Hunter Zolomon as Zoom), but it was changed to Barry Allen (And again, likewise with Eobard Thawne as Professor Zoom, but in Zolomon's costume).
** Concept Art was drawn for Vic Sage as ComicBook/TheQuestion, but the one you encounter in-game is Reneé Montoya. Though Vic is mentioned in the Briefings found during "The Hunt" challenge mission.
