Kabuterimon's Electro Shocker

Izzy makes an interesting discovery, in a strange factory with no particular purpose, whilst the others are forced to run from the unstoppable Andromon.

Synopsis
The next destination on the kids' journey is a mysterious factory in the middle of nowhere, where strange objects are built by machines, and taken apart in a seemingly never ending process. Izzy takes interest in the power source of the factory, an enormous battery cell, and begins experimenting with it. Meanwhile, Tai, Sora and Joe manage to activate a robot called Andromon, who's stuck in a piece of machinery. But he's less than grateful, and begins chasing them through the factory. Once the group has reunited, Agumon and Gabumon digivolve into Greymon and Garurumon, but Andromon quickly brushes them away. Izzy then discovers the secret to Tentomon's digivolving, and he manages to become Kabuterimon. After Izzy figures out Andromon's weak spot, he is quickly defeated to reveal yet another black gear. Once Andromon has recovered, he leads the kids to a sewer pipe leading out of the factory.
