Doomsday is the secondary antagonist of the animated film Superman: Doomsday. In this animated feature based closely on the comic story "The Death of Superman", the Doomsday monster is discovered buried deep beneath the Earth by LexCorp. During excavation, the capsule containing it is damaged and the creature reanimates, tearing its way out and killing all of the LexCorp staff on-site. Doomsday proceeds to tear a path of destruction and death as it heads in the direction of Metropolis, compelled to kill every living thing in its sights.
When the monster arrives in Metropolis, the military are unable to stop it and many soldiers are killed. Superman arrives to bring Doomsday's rampage to a halt, but finds that the beast is just as strong as he is, if not stronger, and its complete lack of any feelings means that it does not hold back as it attacks the Man of Steel. A terrifying battle takes place which goes on for several minutes as Superman and Doomsday brutally beat each other, tearing up the city as they go. In the end, Superman defeats Doomsday by grabbing the monster and flying up into orbit, then plummeting back down with the force of a comet. The impact appears to finally kill Doomsday, but at the cost of Superman's life as well.
