All the heroes are accessed from the start in the console version of the game, but in true tournament game fashion in Injustice 2, you must accumulate champion pieces by playing the game. To access these shards, complete the challenges and complete the plot, which can then be combined to unlock the hero of your choosing. Shards can also be used to extend up a hero, and whether to unlock someone new or continue updating your entire character collection is often a tricky decision. Each hero is divided into many classes, such as the Might class for Super Woman. Each class has a weakness and strength that creates fighting gameplay for Pokémon-like heavy metal.
