Characters are groupings of playable heroes. Different versions of heroes from a single character are called variants and often share some similarities, and usually the same Supermove (the terminology from NetherRealm Studios are often inconsistent, and they may use "character" to refer to heroes, but on this wiki the aforementioned terminology is used for consistency, subject to change).
There are 38 total characters in the console game, and as of 24 April 2019, there are 34 characters and 88 heroes in the mobile game, which includes at least one variant for every console character, with the exceptions of The Atom, Enchantress, and Teenage Mutant Ninja Turtles.
Two of the playable heroes in the mobile game are not directly based on characters in the console game:
- Multiverse Batwoman is unique and has Batgirl's supermove from the first Injustice game.
- Nightwing has his supermove from the first Injustice game as well, even though his appearance can be mimicked by Robin in the Injustice 2 console game through its gear system.
Heroes like Silver Banshee, who has a slightly altered supermove with a different name, are still considered the same character (in this case, Black Canary (character)).
