A Golden Bug! The Mystery of MetallifeKuwagamon

Synopsis
Wanting to find out the full story behind the Digimon Hunt, Xros Heart finds a lead in a mythical Digimon named MetallifeKuwagamon. Tagiru's insect-collecting classmate Kaneda enters DigiQuartz with Tagiru and Hideaki. Later on, to Kaneda's dismay, the bug he caught is actually MetallifeKuwagamon who later on takes the boy as a hostage to cover his escape. Eventually, Tagiru and the others find MetallifeKuwagamon with Arresterdramon defeating him while Tagiru saves Kaneda. However, Tagiru realizes MetallifeKuwagamon cannot be captured as the Digimon reveals that his data belongs to an evil Digimon Hunter. Suddenly, before he can reveals his master's identity, an evil being with red eyes and mouth deletes MetallifeKuwagamon before attempting to suck the Digimon Hunters into it. But at the very last minute, Tai Kamiya (who arrives with WarGreymon) and Marcus Damon (who arrives with ShineGreymon) arrive to the Hunters' aid. With the two youths' help, Tagiru remembers his bond with Gumdramon and that allows Arresterdramon to assume his Superior Mode and destroys the evil being. Tai and Marcus take their leave, with the former explaining to a confused Tagiru that he will know them soon enough. Meanwhile, while trying to help Nene in Hong Kong's Digi Quartz, Christopher encounters Mimi Tachikawa and Rika Nonaka as they intend to help the two in relation to the final battle about to occur in Japan very soon.
