Jon is upset when he learns of his father's "death" years before during his encounter with Doomsday. As Lois and Clark explain the story to Jon, they are interrupted when a new monster attacks Metropolis that has all the powers of Doomsday plus some additional abilities of its own. Superman goes head-to-head with the new monster, Doombreaker, but onlookers fear a similar result to Superman's earlier battle with Doomsday.
