Trivia

 * The game tries to balance the nature of most of Warner Bros. Animation franchises' family-friendly tone in contrast with the more mature tone of franchises like Rick and Morty, Mortal Kombat, Lollipop Chainsaw and Gen:Lock, especially considering the DC universe and RWBY can easily fit both, by featuring a more actiony vibe yet with the most mature parts toned down.
 * The game's developers have justified the choice of the game being 2D rather than CGI due to the fear of some of the most stylish designs (like the ones of The Powerpuff Girls) could fall into uncanny valley as other games have used a 2D-style graphic before.
