Art.

An Art. (アート Aato) (short for Artificial) is a special type of Digimon that appears in the manga Digimon Next. These Digimon are the ones created by humans via the virtual pets. Art. digimon seem to be unable to survive once abandoned by their Tamers, as they require their Tamer's love and attention to survive.

One such example of this is a Chibimon that was found by the Holy Angemon that was in charge of guarding the System World. Chibimon became exhausted and sick before dying due to his abandonment.
