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. He was once a Vaccine Digimon used to restore crashed computers, but he was attacked by a strong Virus Digimon, which destroyed his logic circuits and made him run wild. Despite his small stature, Datamon can easily delete bigger and stronger Digimon.
