his counterpart to bring prime Superman over to help. During the ensuing battle, Superman overpowers the Regime's top lieutenants and persuades Yellow Lantern to surrender, before confronting his counterpart at the Fortress of Solitude, pitying his loss yet declaring the planet needs freedom. When Regime Superman vows to bring prime Lois over, his prime counterpart reminds him Lois would be horrified at the tyrant he has become. Following Regime Superman's defeat, the Regime is dissolved and its members imprisoned, barring Flash, who is paroled, and Yellow Lantern, who is taken to Oa to be rehabilitated. While the prime heroes and Joker return to their universe, Insurgency Batman and prime Superman oversee the imprisonment of the latter's counterpart within a cell emitting red sun radiation that renders him powerless. As they walk away, Superman voices his fears that he could also go down a dark path if a similar tragedy happened to him. Batman says that he hopes this never happens, but will stand up to him even if so. Superman chuckles and tells him to get in line. Regime Superman's eyes glow red, indicating he still has some degree of his powers left. Characters The roster was selected internally by NetherRealm Studios with input from DC Comics. The main goal during the selection process, which took around three to four months, was to create a cast featuring a wide variety of characters. Characters were chosen based on criteria such as size, ability, gender, popularity, and how well they fit within the Injustice storyline. The addition of each playable hero and villain required about six weeks of development. The characters were designed with the intent to make each fighter unique, and fighting styles and movesets were tailored to the lore and personality of each character. Ed Boon stated that DC Comics had given NetherRealm a large amount of freedom with their properties, allowing them to put their own spin on characters. Several other characters from the DC Universe, such as Darkseid, Scarecrow, Metallo and Gorilla Grodd, also appear as non-player characters, making cameo appearances in story cutscenes, stages and other game modes. Outside of the DC universe, Scorpion from NetherRealm's Mortal Kombat series appears as a downloadable guest character. The playable characters are: Aquaman Ares Bane Batgirl Batman Black Adam Catwoman Cyborg Deathstroke Doomsday Flash (Barry Allen) Green Arrow Green Lantern (Hal Jordan) Harley Quinn Hawkgirl (Shiera Hall) Joker Killer Frost
