King Drasil

King Drasil is the mysterious host computer who rules over all of the "Digital World" on one Server of the Network. Its primary form is that of the Server Tree, an enormous, sacred tree. Bagramon replaced its lost eyes and right half of its body, taken from it by God, with wood cut from the sacred tree. It has created an avatar in the form of King Drasil_7D6, whose body has many unidentified details, and Shakamon is rumored to be the being closest to King Drasil in the Digital World. It gathered the Royal Knights in order to manage the world, and it seems that its will will eventually lead the Royal Knights to cross Servers to the Digital World: Iliad Server and meet the Olympos XII face-to-face.

King Drasil's design, showcased in Digital Monster X-Evolution, is a pristine crystalline sphere on a similarly-formed.

The Server Tree's design is derived from the mythological, an immeasurably large tree which supported the various worlds in.

Several of King Drasil's crystals act as its security system, and possess the ability to fire beams of energy or absorb and reflect attacks.

Digital Monster X-Evolution
The original Digital World was cultivated and populated with Digimon by King Drasil. However, the continuous multiplication of Digimon left the computer unable to handle the data load, resulting in an apocalyptic event known as the "Digital Hazard" that saw the Digital World begin to collapse. King Drasil initiates "Project Arc", hand-picking a small number of Digimon to survive the catastrophe and transplanting them to a new Digital World it created. However, Digimon who survived the death of the old world by way of the mysterious "X-Antibody" appear in this new Digital World, disrupting King Drasil's plans.

In order to move Project Arc into its second phase—the complete extermination of the Digital World and all Digimon life—King Drasil creates an experimental being,, from whose data it creates a vast army of , as well as its personal protector, , who later becomes. Discovering King Drasil's true intentions, the Royal Knight turns on it, and after becoming an "X-Digimon" himself, sends Dorumon to his comrades,  and, in an attempt to bring an end to the fighting.

In the Royal Knights' stronghold, Dorumon is revealed to be, the legendary leader of the Royal Knights. This information is enough to convince Omnimon to face King Drasil, and he goes with Alphamon to seek counsel with his master, defeating DexDorugoramon and Dexmon, who bar their way. As this is happening, King Drasil initiates the second phase of Project Arc, and the Digital World begins to die as the DexDoruGreymon sweep across it, reality crumbling in their wake. To stop the computer's scheme, Omnimon—transformed by Alphamon's X-Antibody—strikes down his master with his "All Delete" attack, destroying King Drasil and allowing the Digital World to be reborn.

Later, Omnimon and Gallantmon speculate on King Drasil's intentions. For all that it has done, its reason remains unclear to both Knights—but in the end, Gallantmon believes that King Drasil was, just as all Digimon were, fighting against its own inevitable destruction.

They then ask King Drasil not to interfere with Digimon too much and that the two of them will always rush to help the Digital World in times of crisis.
