In DC Comics
, Doomsday is the name of the villain
responsible for killing Superman. Doomsday is the result of an alien genetic experiment
conducted hundreds of thousands of years ago. A nearly indestructible
, unstoppable creature, Doomsday was designed to be the top of the evolutionary
scale. After he escaped his underground prison
, Doomsday headed towards Metropolis
, leaving a trail of destruction
in his wake.
After an extended battle
that left the Justice League of America
and Metropolis in ruins, Superman managed to stop Doomsday at the seeming cost of Superman’s own life.
Superman has battled Doomsday twice more. The second meeting left Doomsday stranded at the end of time. The last time, Superman and the new Justice League of America had to stop Doomsday after Brainiac
took control of him.
On a side note, many comic book Superman fans were pissed
at the thought that a totally new, unheard of villain, which Doomsday was at the time, being able to kill Superman. Most agreed that if Superman should perish, it should be at the hands of one of his old foes, like Lex Luthor
