>>46178455Villain of the Wonderswan games, themed after the Millennium Bug. Before the start of Adventure 02, it exploded in Ken's face to infect him with its Dark Spores and turn him into the evil Digimon Emperor, all as part of its plan to manipulate Ken into creating Chimeramon so that its data would travel back in time and fuse with Machinedramon to create itself.
It's yandere for Ryo, the dimension-hopping protagonist of the Wonderswan games. Eventually it dies but fuses with Ryo's partner Monodramon to become Cyberdramon, who's with Ryo when he becomes a major character in Digimon Tamers. You may remember a scene in Tamers where Cyberdramon devolves to Monodramon and Ryo suddenly starts crying tears of joy and saying "It's been so long!" for no explained reason.
Also it's the main villain of the currently airing Digimon Adventure remake. And in this continuity it's shown that MetalGreymon can dark evolve into Machinedramon through rage, which raises all sorts of questions.
