1. Red Hood
Now, you may be wondering why The Joker isn't listed here and this is the reason why. I understand that many of you didn't like Jared Leto's take on The Clown Prince of Crime in Suicide Squad and that you would rather not see the villain take centre stage in a Batman movie for the third time, but using Jason Todd as the lead antagonist in this release would mean The Joker could appear in flashbacks and sets the stage for him and The Dark Knight to once again cross paths in the present day somewhere down the line.
Fans have made it clear they want to see Batman take on the Red Hood on the big screen and Warner Bros. must realise that they need to get that group of moviegoers back on side after some creative decisions (the looks of both The Joker and Doomsday spring instantly to mind) which have alienated them. Deathstroke could still make a brief appearance as an aquaintance of Todd's, but the Red Hood showing up opens the door to all sorts of possibilities, including a spinoff for the former Robin.
Which of these villains would you most like to see show up in The Batman? As always, be sure to let us know your thoughts in the comments section down below.
