Datamon

Datamon is a small Machine Digimon used for restoring computer data. He is known as Nanomon in Japan. He is very good at fixing and using electrical equipment, but he does not work well with people.

Digimon Frontier
A merchant at the Autumn Leaf Fair, Datamon obtained the four D-Tectors from the Toucanmon. Though he liked to help Tommy and Arbormon, it was clear that his motive was simply a desire to make money. At any rate, this Datamon ended up a good guy, for he refused to help Arbormon after seeing Tommy's bravery and honesty in the camcorder the Toucanmon bought from Datamon. His assistance turned out to be of great importance, as he gave Tommy his Beast Spirit. He was also among the Digimon leaving the Autumn Leaf Fair when the Royal Knights targeted it but earlier helped the kids, Sepikmon and 3 of the Toucanmon prepare a defense against them.

Between those events, a trio of other Datamon were seen in the employ of Mercurymon and Ranamon, attempting to remove the Spirits from the D-Tectors when they captured Tommy Himi, Zoe Orimoto and J. P. Shibayama. When Agunimon and Lobomon freed them, the Datamon quickly made themselves scarce.
