Injustice 3: 10 Characters NetherRealm Must Include
4. Booster Gold
Booster Gold has had quite the resurgence as of late, appearing in both a recent Batman Rebirth story-arc and also as sort of a main character in the Injustice 2 comic.
Michael Jon Carter is actually from 25th century Gotham City, becoming a superhero after stealing several artefacts from a museum in Metropolis, his original goal being to travel back to the 20th century and earn a comfortable living for himself. However, after the death of his sister, Gold began to take crime-fighting more seriously.
Gold's technological abilities and frequent use of time-travel would make for a brilliant move-set and adding him to the character roster of the next game would be logical, due to his frequent appearance in the Injustice comic, plus he would also bring some more joy to the often bleak Injustice-verse - well for those who are yet to read the prequel book, at least.
