Wait a minute. As usual for DIGIMON fans, we’re thinking too hard. They said eighteen new digimon would receive the X-antibody, and I count eighteen in the ones we already know. That means the two new ones aren’t new Xevolutions; if they’re Xevolutions at all, they’re old ones. And in chapter five they said that GranDracmon was up to some shenanigans involving DeaXlution.
