Christopher and Metal Greymon's strength is put to the test when they join Mikey and Shoutmon on a rescue mission to save the rest of the Fusion Fighters from being deleted at the hands of the Dark General Dorbickmon.
Now a united group, teams Blue Flare and the Fusion Fighters head to Vampire Land, where they discover a group of helpless Digimon being kidnapped by the fearsome vampire Dark General NeoMyotismon.
When Metal Greymon is absorbed by NeoMyotismon, Mikey and Shoutmon search for the legendary White Lopmon, who may be the key to defeating NeoMyotismon and freeing their friend.
The Fusion Fighters travel to Honeyland, where innocent Digimon are being drained of their energy in order to make digi-honey. They also meet a potential new ally named Mervamon, but her extremely narrow-minded focus on defeating the Dark General and inability to work with the team alienates several of the Fusion Fighters.
