Secret Origin

Yes, we did have an origin for Superman, in Man of Steel, most likely inspired by Birthright. However, and as said a couple of times before, the director of the sequel won’t adapt any of these storylines in full.
Thus, from the Secret Origin storylines, we should be introduced to Sam Lane, the general who accuses Superman of being an alien and, thus, an enemy. And this will fall in line perfectly with what has happened in the DCEU, especially since all aliens will be proved to be enemies (Zod, Steppenwolf, the Parademons). And, once again, Superman will have to fight an army.
Now Lex Luthor comes into play – or, better yet, LexCorp, which has developed a new kind of weapon. And that is Metallo. The fight ensues and this time Kal-El cannot take it into a deserted/abandoned area. Which is for the better, since the populace will see him struggling to defend the bystanders from Sam Lane’s soldiers and Metallo.
And in the end, Superman becomes the symbol of hope.
