Iron Vegiemon

Matt and the other kids answer a call for help from Gabumon, whose attempts to liberate a village of captive Digimon have so far failed, thanks to RedVegiemon, who is under the Emperor's control.

Synopsis
In the Digiworld, the three new DigiDestined along with Kari, T.K and Tai are helping Digimon escape from the Digimon Emperor's jail. is suspicious that it was too easy, and he must've planned it like that for a reason. Just before returning home, notices a large tower, and  is then revealed to be one of the emperor's captives. They arrive back in the real world is shocked to find out the others have brought back the Gotsumon from the Digital World. They decide to pose as art sculptures in case anyone comes in the computer class. Izzy asks Yolei to borrow her Digivice as it seems only the new ones can open the gate to the Digital World, and he would like to study it more.

Meanwhile, back in the Digiworld, Gabumon is helping some Gazimon escape from the emperor's jail. He is caught by RedVegiemon and is beaten until he falls off a cliff into the water below. He washes up on shore next to an old television, desperate to find.

At that moment Matt is performing in a concert with his band. He and T.K. talk after the show and they meet Davis' sister, Jun Motomiya. They then receive an emergency message from Yolei. She got a message from Gabumon saying that he needed help. The DigiDestined ready themselves go, but Yolei is unable to because Izzy is still examining her Digivice.

Once in the DigiWorld, Matt reunites with his partner Gabumon. Before going back into the jail, they decide that this might be part of the emperor's plan, and much to Davis' dismay, that they should rescue all the hostages. The kids (and Gabumon) pretend to be captured slaves while their partner Digimon pretend to be the ones who captured them. They easy gain access from the Vegiemon and escape from the cell they are put in, but are once again caught freeing Digimon.

When they are trying to escape, Davis begins to lose his temper again because no one listens to what he has to say, and he also gets mad about T.K. and Matt meeting his sister. This makes Matt mad, saying that he needs to learn more respect. Kari also gets mad because Davis was trash talking his sibling, and he becomes upset because he thinks Kari hates him. The Vegiemon catch up to the group and then begin attacking them. Their Digimon are unable to Digivolve because their partners are constricted by the Vegiemon. Veemon gets beat repeatedly by RedVegiemon, and Davis is struggling, frustrated that he is unable to help. Gabumon is also unable to Digivolve because apparently Digimon cannot Digivolve naturally because of the Control Spires. While beating Veemon, RedVegiemon accidentally destroys the nearby spire, and thus Gabumon is able to Digivolve into and with the help of  they defeat RedVegimon. Tai, Izzy and Yolei arrive with their Digimon and realize that the Control Spires power the Dark Rings. Armor Digivolves to and finishes destroying the Control Spire to free all they nearby Digimon from the emperor's control. The DigiDestined deduce that they have to destroy the Control Spire for any particular area to disable the Dark Rings in said area. Luckily enough, Izzy has found a map of the Spires on Yolei's Digivice, one which they can use to help with the task.
