Superman, Batman

Newly-elected president, Lex Luthor uses a large chunch of Krypton hurtling toward Earth, as an excuse to declare Superman a criminal and put a huge bounty on his head, sending every metahuman with a grudge after the superhero. The Man of Steel teams up with Batman and a newly-discovered Kryptonian cousin,Kara Zor-El, aka Supergirl, to destroy the asteroid, clear his name, and battle other threats to Earth's safety such as Darkseid.
