Host Computer

A Host Computer (ホストコンピューター Hosuto Konpyūtā), or simply Host (ホスト Hosuto), is a supreme AI ruler system that serves as the central server and administrator for a specific Digital World, of which they are responsible for their rules and stability, often having significant authority over the Digimon within it and maintaining its overall structure. For this reason, they are sometimes referred to as "Gods" of their respective digital realms. They can create avatars or have a form of consciousness or physical manifestation, like a server tree; they also command powerful organizations to carry out its will and enforce their rules, like the Olympos XII or the Royal Knights.

Hosts can sometimes clash with each other, with their different goals, leading to conflicts between their respective Digital Worlds.
