Datamon

Datamon is an evil Digimon in the anime, Digimon. He is considered to be a major antagonist, as he is not allied with Etemon during the Etemon arc, but only appears in two episodes.

He was held prisoner in the pyramid, but when the Digidestined set him free, he kidnapped Sora and Biyomon and attempted to clone Sora to defeat Etemon and rule the Digital World. The other Digidestined stopped him, and when the fight with Etemon came, Datamon dropped computer viruses into the pit leading to the core of the Dark Network. Datamon and Etemon fell in; Etemon was fused with the Dark Network, but Datamon was killed when he fell in there.
