In one Marvel Comics world, the children of the Fantastic Four and the X-Men would together create one of the world's strongest and most dangerous mutants. The reality-hopping Exiles team found themselves on a world where most of the world's superhumans were either dead or in captivity, with David Richards responsible for it. This son of Franklin Richards and Rachel Summers was believed to either grow up and save his world from the Sentinels that killed his parents, or grow up to become its new tyrant. Despite the Exiles' good intentions, they learn that some destinies are inevitable, as David's path appeared to be destined for darkness no matter what.
In Exiles #12 by Judd Winick and Mike McKone, the Exiles meet another team called Weapon X, a group of individuals from other realities who are comfortable with lethal solutions to their missions. They learn that this world has been overtaken by the Sentinels who keep the surviving superhumans in captivity with inhibitor collars on to neutralize their powers. Both teams together storm a base where they rescue a group of mutant children, including their target, David Richards. They learn that David's mutant powers will be strong enough to defeat the Sentinels, but instead of granting freedom, he'll seek to enslave humanity's survivors. While Weapon X and the Exiles argue and fight over the orders to kill him to prevent this future, the Exiles agree that former Weapon X leader Sabretooth will stay behind to raise David and the other children, hoping his influence will prevent the future they were foretold.
