Injustice 3: 10 Guest Characters NetherRealm Must Include
6. He-Man And She-Ra
Mattel's Masters of the Universe is one of the most iconic toy lines in existence, and one that probably wouldn't have existed had it not been DC Comics' help in charting the mythology of the series even before the cartoon came into existence.
As such, it feels like a great time to bring Prince Adam and She-Ra into the next Injustice; the latter because she's currently making ways in animation, and the former because he's just as iconic.
Aside from both characters' respective histories, the sheer novelty of having Adam walk onto the screen, shout "I have the power!" and then transforming into He-Man would just never wear off - likewise for She-Ra chanting the nearly as familiar "for the honour of Grayskull!" just before assuming her warrior form.
Heck, maybe even throw Skeletor in for good measure. It would all be worth it just to hear Alan Oppenheimer's evil voice again.
