Humans

Humans are a species of mammals found on Earth. Unlike Digimon (creature) they cannot digivolve (save for the Digimon Frontier cast), but with the aid of a Digivice can use their emotions and energy to facilitate digivolution for the Digimon they have formed a partnership bond with. In Digimon Adventure 02 every human in the future has a Digimon but in Digimon Data Squad nobody knows about Digimon except the DATS and Marcus's family.
