* How do the good digimon keep resurrecting? Patamon is completely possible, since the x-antibody is supposed to be a power boost. Dukemon I'm willing to accept, since he was apparently planning for it and his death didn't look standard (no idea where he got the x-antibody though). But how did metalgarurumon come back? Not only did he keel over dead, his last act was to give up his x-antibody. Yet when we see him again, his looks haven't changed back to that of a normal metalgarurumon.
** Here, the dead seem to leave their bodies behind(seeing Leomon in the opening) with all those who burst into particles not really dead. It is weird but internally consistent.
** Also, a possible FridgeBrilliance and ViewersAreGeniuses for Dukemon's resurrection. [[AllThereInTheManual In the official handbook]], Dukemon is described as containing contradictions and is an unstable virus. And we all know virus are notoriously hard to kill in Digimon.
** My persona theory, which is only supported by [=MetalGarurumon=] X and Dorumon coming back, is that the X-Antibody leaves a "seed" behind, and that it takes some time for it to grow back into a new X-Antibody, and that this was unknown even to the X digimon, as [=MetalGarurumon=] X seemed to fully expect death.
* Here's a much bigger headscratcher: [[spoiler: Alphamon had just died and given his X-Antibody to Omegamon, which led to Omegamon X using his All Delete attack to erase what was left of the Digital World, but the next thing we see is Omegamon X and Dukemon X standing on a hill talking. What has this troper confused is how the Digital World was able to come back without its master control program?]]
** Here's a potential answer: [[spoiler: the whole movie was a XanatosGambit combined with a ThanatosGambit and a ZeroApprovalGambit. Yggdrasil knew that it had made severe mistakes, but because [[ICannotSelfTerminate it was just a ball on a pedestal]], it needed to set things up so that this would all happen. [[FridgeBrilliance And the reason it didn't just ask one of the Royal Knights to do that in the first place, ironically, is because even they would have questioned if it hadn't received a virus somewhere, since they were meant to protect it as well as enforcing its will!]]]]
** Regardless, we are told that Yggdrasil had already transferred the digimon that it had deemed necessary to a new digital world. What we witnessed was the final death of the Old World, enabling the mons to live in the new world that Yggdrasil had planned for itself.
