Valeria von Doom first appeared during writer Chris Claremont and artist Salvador Larroca's run on Fantastic Four, suddenly materializing in the Fantastic Four's headquarters, professing to be from the future, and the daughter of Doctor Doom (Victor von Doom) and the Invisible Woman. This was very disturbing to the Fantastic Four, but after an initial period of conflict, the Invisible Woman accepted Valeria into the FF's home, and she aided them on several missions.
