Beast Boy
The Teen Titans have had some representation in the Injustice series, thanks to Cyborg, Raven, Nightwing, Robin, Blue Beetle, and (the upcoming) Starfire. However, poor Gar Logan has been noticeably absent from the lineups, which is rather surprising considering his transforming abilities and popularity.
Imagine playing as Beast Boy and having the ability to morph into animals, such as an elephant and monkey, as you pummel your opponent like a boss? It would be like executing smaller Animalities that don’t suck (spoiler alert: all the ones in Mortal Kombat did). If the developers want to take the fun route with the character, the moves could even be more outrageous and humorous than usual, adding some laughter and mischief (two major Beast Boy qualities) into the fray.
There are few comic book heroes as lovable and good-natured as Beast Boy, ensuring that he’s been a mainstay in the various Titans teams for many years now. Now, he could prove to be a wonderful addition to this title as well.
