Hypnos

Hypnos is the name of a fictional organization from the Digimon Tamers TV series. Believed to be named after the title of a minor tale by horror author HP Lovecraft.

Hypnos' purpose is to detect Digimon when they Bio-Emerge in the real world, and to prevent it if possible. However, their efforts at first proved unsuccessful. As time went on, they developed new and better methods of attacking Digimon, but these techniques proved ineffective against the Devas. In their efforts to better understand and defeat the Digimon, Hypnos recruited the scientists who originally made the Digimon, attempting to use their knowledge to create a successful anti-Digimon weapon.

After the Tamers entered the Digital World, Hypnos' objectives changed; they now sought only to bring the kids home. This new realization came after Hypnos' leadership realized that not all the Digimon were evil. Eventually, their efforts allowed the children and their Digimon to return to the real world. Hypnos later helped in the battle against the D-Reaper.

Programs
During their attempts to destroy Digimon, who were composed of data, Hypnos developed two programs meant to serve that purpose.

Yuugoth
Essentially a blast of virtual energy, the Yuugoth program locks onto and strikes Digimon, supposedly deleting them. The Yugoth program was later downloaded into Gallantmon's vehicle Grani.

Juggernaut (Shaggai)
The most powerful of Hypnos' weapons, the Juggernaut program is a digital vortex that draws in all data nearby, including Digimon. The program nearly succeeded in destroying many Digimon, but inadvertently allowed one of the Devas to pass into the human world. The Juggernaut's subsequent uses were equally ineffective, until it was downloaded into Terriermon. As MegaGargomon, he and Henry used it as part of Operation Doodlebug, regressing the D-Reaper back to its original harmless state.

Ark Program
A transport program created by Hypnos with the Monster Makers' help, the Ark's purpose was to bring the Digi-Destined home from the Digital World. However, the program evolved beyond it's original purpose, actually developing intelligence. Later, when the Digi-Destined and their Digimon were locked in battle with the D-Reaper, Hypnos recovered and modified the Ark into an attack vehicle, and attempted to materialize it in the human world. However, it was unsuccessful until Gallantmon channelled his energy into it, creating Grani.
