Humans

s (人間) are the dominant species of the Real World. Some 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 human forms. Also, it is possible that the God of the Digital World is a human.

Human-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 Partners, allowing them to digivolve to the Mega level.

Digimon Data Squad
Every human possesses an aura-like "D.N.A." made from their emotions. By charging the D.N.A., a human is able to make their partner digivolve.

Digimon Fusion
A "General" or "Hunter" is required in order to create a DigiFuse between the Digimon in their army. Some Generals or Hunters 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 create Digifuses. It is also possible to digifuse humans with Digimon.

Digimon Universe App Monsters
In the Real World humans can't see Appmon that haven't been apprealized unless they have an App 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 Order
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.
