Aquaman, Shazam, Black Adam, Sinestro, Doomsday, Ares.
They keep saying not everyone in the story mode will be playable, but I'm not sure what that means for these characters.
They way they talk about Ares and Aquaman in that article really implies they would be playable, Sinestro has to be playable or he wouldn't be in a cutscene anyway cause hes a fucking alien who has no buisness being there in the first place. Doomsday is on the stick, and Boon hinted he was playable in a tweet.
So that leaves Black Adam and Shazam, but if one was playable, the other would just be an alt, and Captain Marvel was in MKvsDC, so it would be weird to not have him playable.
W/e probably going to have to wait 3 months to see whats up.
