If I had a Tail Hammer

The DigiDestined are hard at work rebuilding one of the many devastated towns of the Digital World, until a nearby control spire, thought to be inactive, starts causing problems for the group.

Synopsis
Ken finds a strange woman in his room, but she refused to tell him who she is. Meanwhile, the DigiDestined continue their cleanup. Davis realizes, Veemon can‘t Digivolve. Kari and T.K. sneak off to see if their Digimon can Digivolve but they can‘t. They wonder if the Control Spires are active again. Cody and Digmon are underground when Thundermon attacks them. Armadillomon Digivolves to Ankylomon and emerges from beneath the ground. Then a mysterious Digimon destroys Thundermon and lands next to Ken. He disappears. Oddly, the control spire they discovered had vanished.
