Brainiac

There were multiple hints of Brainiac arriving on Earth in Batman v Superman. And the most obvious ones were dropped by Lex Luthor. Who doesn’t want to see the Collector of Worlds? Who doesn’t want the DCEU to delve into the mythology of Kandor?

With the discovery of other peaceful Kryptonians, Kal-El might actually find in himself what he needs to become the symbol of hope.

Yes, Brainiac may be a bit too big for this Superman. However, since I don’t believe that there will be a third Man of Steel, this villain needs to appear on the big screen. So bring him! After all, with all his technology, he must have noticed the same signal found by Zod and, afterwards, by Darkseid.
