While the latter two characters mentioned above are exciting new arrivals in their own right, they're somewhat overshadowed by the Ninja Turtles.
Injustice 2 has been out for almost six months, and in that time, the game's roster of fighters has grown significantly.
I imagine changing their gear will swap between the four brothers since Michelangelo, Leonardo, Donatello, and Raphael are all considered one fighter at the end of the trailer. There had been some serious guessing games going on as NetherRealm fans tossed ideas around about who could be coming to Injustice 2. Players can play from the biggest DC roster ever offered in a fighting game, from classic fan favorites such as Batman, Superman, Supergirl and Aquaman, to astonishing new villains like Atrocitus, Gorilla Grodd, and Deadshot.More news: Ruben Loftus-Cheek had 'vision' to leave Chelsea and accelerate career
It's not quite clear how the gameplay for the Ninja Turtles will work for the fighting game.
It is unclear if all four of the turtles will be playable as separate characters or, as Leo puts it in the trailer, "We fight as a team" in the game.
These DLC characters, and the ones that came before them, are included as part of the Ultimate Edition of Injustice 2 or can be purchased in the upcoming Fighter Pack 3 DLC. A PC version will be out next week. The Atom will also be available for early access on December 12.
