10) Killer Croc
Batman took on a foe far more powerful than he is in The Dark Knight Rises, and while going down that route again may feel a little redundant, Killer Croc is different enough to ensure that this wouldn’t feel like more of the same.
The villain is, of course, set to be introduced in Suicide Squad, and if the rumours are to be believed, pretty much the entire roster of that team are in Belle Reve because Batman put them there. That gives Croc some potentially very interesting history with the Caped Crusader to mine for this movie, while his introduction as part of Task Force X could help to get viewers invested in him.
Of course, the decision to go down the practical route with Killer Croc means he’s not quite as intimidating as his comic book counterpart. That, however, could easily be fixed by having him undergo a transformation into the horrible monster you see above.
Admittedly though, having one of Suicide Squad‘s supporting villains take on a leading role in a Batman movie might not be too smart, but as a minor threat in the first act or even as a henchman for someone else, Killer Croc is a character who could definitely make an impact in this trilogy, especially if he’s handled in just the right way.
