Comment:
Continues from the previous issue and continues in the next issue
Synopsis:
Batman and Superman have been buried alive by Metallo and Batman must use Superman's
invulnerable body as a shield as he blasts their way out and into the sewer system. From
here they make their way to the Batcave, where the kryptonite bullet in Superman's chest
is removed and Batman learns what Superman came to tell him - that evidence has suddenly
surfaced that Metallo (or John Corben as he was then known) may be responsible for the
killing of Thomas and Martha Wayne. A version of Superman from the future suddenly appears
in the Batcave, warning them to beware of Luthor and that they are about to make a mistake
which will result in the death of everyone except Superman. As he disappears, Luthor reveals
to the American people that an asteroid comprising remains of the planet Krypton is heading
for Earth. He claims that Superman is responsible for this and offers a substatial reward
(i.e. one billion dollars!) to anyone who can bring him in.
