At the start of the new imprint, 2099: World of Tomorrow, X-Nation is split. December, Twilight and Metalsmith join Father Jennifer D'Angelo and Ben Grimm in a trip to the Alchemax Mars colony to see if it is possible for the remaining residents of Earth to relocate to Mars. There they meet Dr. Isaacs, Clarion's mother (though it is never shown that the others make this connection), and the resident martians, known as the Takers. It is revealed that several years prior the Phalanx decimated Mars, killing most of the Takers, leaving only a dozen or less. Smith and Twilight travel with them on a rocket ship, landing on the Phalanx planetoid that is trying to assimilate Earth and battle to destroy the Phalanx. From Earth, the semi-sentient database robot built by Reed Richards uplinks to the collective and dubs their plan to destroy all human life as "evil". As such he triggers the self-destruct sequence of the planetoid and it explodes, killing the remaining Takers as well as Smith and Twilight. December and Dr. Isaacs are left on Mars to mourn the loss. It is also revealed that Dr. Isaacs had cloned Clarion before leaving for the Mars project, but none of the clones survived.
