1) Brainiac
The odds-on favourite to go against Henry Cavill in Man of Steel 2, however, is Brainiac. It’s not hard to see why – the villain is most probably the biggest Superman antagonist not yet adapted to film. Not including Darkseid, of course, as it has been all but confirmed that he will appear in Justice League.
Brainiac is ripe for a movie appearance as he’s both a formidable opponent and has a personal history with Superman, or at least his race. He’s often depicted as a highly intelligent android who shrunk the Kryptonian city of Kandor.
Interestingly, the viral marketing campaign for Batman v Superman already hinted at a DCEU version of Brainiac. A mocked-up website introduced the Lex/OS, apparently the world’s first operating system to have autonomous thought.
Clearly, Luthor has not seen Avengers: Age of Ultron, or he’d know that this is not a good idea….
