The kids walk for a long time and come upon an odd factory that manufactures useless machinery
but also produces power.
Izzy's computer battery is low so the kids split up to see if they can
find a way to recharge it (and find out what the factory is all about).
Tai, Agumon, Sora, Biyomon, Joe, and Gomamon go in one
group and find Andromon stuck in some gears. When they try to free
him, Tai accidentally starts the machinery. A black gear goes into
Andromon's leg and he starts attacking them. Agumon blasts the
roof with his Pepper Breath and traps Andromon
giving the kids time to
run away.
Matt, Izzy, Mimi, TK, and their digimon find a room with an enormous
battery. Izzy tries to use it to recharge his computer
The kids all meet on the roof of the factory.
Izzy tells about the markings and his conclusion that the digital information in the digiworld is a living source.
Tai and his group dash in and yell at everyone to run (Andromon
is
chasing them).
Agumon and Gabumon evolve into Greymon and Garurumon to fight
Andromon, but they're defeated. Tentomon digivolves to
Kabuterimon and attacks Andromon's
wounded leg, dislodging a Black Gear.
Restored to his normal, good self, Andromon
directs the kids to a tunnel that leads out of the factory.
