Sorry for the double post, but I just got Jessica Cruz in the mobile game's newest event. Her moveset is kind of odd. Normally, a reskin of a character (like John Stewart or Cassandra Cain) has one slightly different combo, one unique special move, and a unique passive ability.
When Deadshot was added, it was notable for the fact that all of his combos were completely new, as were all of his special moves. Since then, he was revealed for Injustice 2, and those combos and specials can be seen in his gameplay.
Jessica doesn't have the same combos as Hal Jordan's various reskins. She has completely new combos, all of her specials are new (except for her ultimate ability, which is Hal's), and her passive honestly reminds me of a character trait (Kilowag coming in and restraining the opponent for her).
Imo, it looks like they may be putting her in Injustice 2, and teasing her in the mobile game like they did with Deadshot.
