Regarding The Suicide Squad, the new characters who’ve been unveiled far include Polka-Dot Man, Ratcatcher, Peacemaker and King Shark.
While it is fun to imagine Dave Bautista playing Bane, particularly if this Bane is more faithful to the one from the comics compared to the versions seen in Batman & Robin and The Dark Knight Rises, keep in mind that for right now, there are no plans to bring the character into the DCEU.
