Piedmon's Last Jest

Just when it seems like they have the upper hand, Piedmon begins turning the kids and their Digimon into key chains, leaving T.K. and Patamon as the group's last hope.

Synopsis
MetalGarurumon returns to fight alongside WarGreymon. Both Mega Digimon seem to have the upper-hand against Piedmon until he turns them, Tai and Matt into key chains. The other children try to run away but they are all turned into key chains except T.K., Kari, and Patamon. When the three of them try to escape up a rope, Piedmon catches up to them. Patamon digivolves into Angemon to try to fight Piedmon, but is easily defeated. Piedmon then cuts the rope, causing T.K. and Kari to fall, and as they fall, T.K. looks at his brother, in the form of a key chain, and is reminded that hope that remains. His crest begins to glow, and Angemon digivolves into MagnaAngemon, who delivers a single slash to Piedmon from above, causing him to fall, seemingly, to his death. MagnaAngemon then returns every key chain into the Digimon and people they once were. They think it's all over until Piedmon resurfaces with hundreds of Vilemon. Just then, Mimi and Lillymon arrive with an army of Digimon, and they all fight back against the Vilemon. MagnaAngemon opens his Gate of Destiny which sucks in all the Vilemon, and WarGreymon and MetalGarurumon send Piedmon in as well, defeating him for good. As light begins to return to the world, Izzy gets a message from Gennai telling them that the Dark Masters were never the real enemy. Just then, the ground shakes and the DigiDestined soon realise that the fight is not over.
