In the end, both writers were satisfied with the results. Millar and Bendis stated that they had many more ideas, but massive scheduling problems forced them out. Instead, they persuaded Warren Ellis to continue the series. Ellis wrote the next arc, "Doom", centering on Victor Van Damme. He made Van Damme a descendant of Dracula, a boy whose childhood ended when he was 10, formed by his severe, authoritarian father. Ellis also fleshed out the hard science fiction element behind the FF, namely writing that they gained their powers because the teleportation changed their "phase space condition" into something from an alternate universe; in laymen's terms, there are multiple conceivable states of an object, a 'phase space' of all the possible ways they could be. While in the N-Zone, each one of them mutated into another form that they could have been. It was also explained that Reed's body functions because his cells were replaced with "pliable bacterial stacks", single cells which duplicate most of the larger functions of the human body and does not rip or tear when he extends.
