Suppose villain cameos and acknowledgements of villains are going to take place in Batman v Superman: Dawn of Justice. Some of these of villains have been made aware of possibly appearing or later appearing in another DC film in the past month or so. If you don’t want to be possibly spoiled, stop reading now…
This recent report is coming from Badassdigest, they’re reporting that supervillain KGBeast will be acknowledged in the film and that The Joker will already exist in Batman v Superman: Dawn of Justice, though he won’t be seen, only acknowledged by Superman.
Now the big kicker of this whole report is, is that Badassdigest willing to state that Doomsday will in fact be appearing in Batman v Superman: Dawn of Justice.
None of these reports by Badassdigest have been officially confirmed by Warner Bros. or DC Comics, take it with a grain of salt.
