Beast Boy
In the campaign of Injustice 2, three characters were name dropped that didn’t appear in the game at all. They were Starfire, Red Hood, and Beast Boy. Since two of those mentioned characters have been confirmed as DLC already there is no reason that Beast Boy shouldn’t also make his way into the game.
The namedrop is just one small factor to why Beast Boy should enter the game. In short, he would just be a tremendously versatile and fun character. There would be almost no limit to the attacks that Beast Boy could pull off. Beast Boy can transform into the entire animal kingdom. His uppercut could involve him turning into a swooping hawk to attack opponents from below to high into the air. He could charge at them as a rhino or elephant. He can even do quick and fast strikes like a small monkey. It might be an animation nightmare but it there is no doubt that it would look and play awesome.
