Injustice 2: 15 Guest Characters NetherRealm Must Include
6. Teenage Mutant Ninja Turtles
Apart from the sheer fact that Leonardo, Michelangelo, Donatello and Raphael are beyond iconic in their own right, the fearsome four also happen to be some of the best comic book protagonists of the century.
That alone should warrant consideration for one of Injustice's coveted guest slots, or at least provoke discussion concerning how Turtles lore could be retrofitted into a DC Universe aesthetic.
Of course, the Turtles themselves are no strangers to the medium, nor are they to DC-themed team ups either. This year they joined the Caped Crusader in the obviously titled though criminally underrated Batman/Teenage Mutant Ninja Turtles mini-series, so there's already a precedent here that Boon and his cohorts could follow.
Again, the Gear System would also enable a variety of on-screen ninjas, enabling players to switch up their play-styles and in-turn injecting a splash of red, blue, orange and purple into PVP combat. Splinter and the Shredder would be good substitutes I suppose, but nothing can come close to the pizza-munching comedy that the Heroes in a Half Shell inspire.
