Humans

s (人間) are the dominant species of the Real World. Some Digimon get along with certain kinds of humans, while others won't easily cooperate with them, and some are able to channel their power. Some Digimon are also able to take on a human form. Also, it is possible that the God of the Digital World is a human.

Human and Digimon Relations
Humans and digimon have a mixed track record of interactions. Some digimon have been known to attack the Humans in the real world while some digimon befriend humans and even become partners to certain humans known as DigiDestined.

In many series, humans are able to assist their Partners in battle:

Digimon Tamers
A Tamer can use "Digi-Modify" by swiping a card from the Digital Monster Card Game through their D-Power to give extra power or weapons to their Digimon Partner. A Digivolution card allows a Digimon to digivolve from their Rookie to Champion level, while a Blue Card allows them to digivolve to Ultimate level.

Some Tamers are able to biomerge with their Partner allowing them to digivolve into the Mega level.

Digimon Data Squad
Every human possesses an aura-like D.N.A. (short for "Digimon Natural Ability) made from their emotions. By charging the D.N.A., a Tamer is able to make their Partner digivolve.

Digimon Fusion
A General is required to make a DigiFuse between the Digimon in their army. Some Generals are also able to allow their Partner to digivolve.

Digimon Xros Wars (manga)
Humans possess the innate "Xros Code" that allows a Fusion Loader to perform DigiFuses. It is also possible to digifuse a human with a Digimon.

Digimon Universe: Appli Monsters
In the Real World, humans can't see Appmon that haven't been appliarised unless they have an Appli Drive.

While in the, humans are made of data. If a human dies in the Net Ocean, their biological form also dies. They can also be infected by the L Virus.

Leviathan has developed a method that can digitize a human and reconstruct them in a different shape, with Hajime Katsura being the experiment's first successful subject.

Digimon Story: Cyber Sleuth
When entering Cyberspace EDEN, humans are completely digitalized, including their minds, which become "mind data" (精神データ). It is possible to hack someone's mind while in EDEN and learn their secrets. It is also possible to erase someone's memories, although never completely, or implant fake memories in someone. The EDEN Syndrome is caused by Eaters devouring a person's mind data, which causes their bodies to return to the Real World in a comatose state.

Digimon World -Next 0rder-
In the, humans are pure data, and as such they can't get tired or feel hunger, unlike Digimon, who need to sleep and eat.

Differences Between Humans and Digimon
Unlike Digimon, humans cannot digivolve (save for the Digimon Frontier cast and the Bio-Hybrids), 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.
