Digimon D-Cyber

is a Chinese Digimon, which was released by Rightman Publishing Ltd. in Hong Kong, China on February 17, 2005. It is based on the adventures of Hikaru Ryuuji, Masuken Kana, Teru Raku, and a young girl named Kiyoshi. It introduces the concept of X Digimon, but their origin is different from that in the Japanese Digimon Chronicle.

Synopsis
Ten thousand years ago, a great and powerful Digimon was defeated and sealed away by the Holy Knights as the "Digi Core". Years later, a virus infected the digital world, leaving only those that possessed the D-Antibody (X-Antibody) remaining. The only members of the Holy Knights remaining are Omega of Power (Omnimon X), Duke of Courage (MedievalGallantmon/Gallantmon X), and Magna of Miracles (Magnamon X).

At the start of the series, the "God of Death" MetalPhantomon draws Hikaru, Kiyoshi, Masuken, and Teru into the digital world. Originally, Hikaru is left alone with his Digimon (which starts out as a Dorimon), and has to battle his friends Teru and Masuken, who are under MetalPhantomon's control.

At one point, MetalPhantomon steals the "Dragon Spirit" of Hikaru's partner, who is now a Dorumon. While MetalPhantomon uses it to revive the Digi-Core, Hikaru, Teru, and Masuken learn from Omega of Power that they can get a new Dragon Spirit from Duke of Courage—with this, they can save Dorumon's life. But when they arrive in Duke's area of the Digital World, they are given a series of tests by Duke's servant, MameTyramon.

After completing the tests and battling Duke himself, they manage to earn Dorumon a new Dragon Spirit. However, now they must battle MetalPhantomon, who has resurrected the Digi-Core as Dexmon. In the end, Hikaru and the others manage to save their friend Kiyoshi, who was sealed inside Dexmon, and return to the real world.

Evolution/Digivolution
In the series, evolution (or Digivolution) is achieved through the generation of "energy spheres", which is formed from the human partner's will. However, if there are negative emotions involved, it can cause the partner to evolve into a savage version in a process called "Death-X (Dex) Evolution." The most notable example of this is when Hikaru's Dorumon warp evolves into a DexDorugoramon.

D-Cyber Digivice
The Digivice for this series is the D-Cyber. The only notable feature of the portrayal of this Digivice is that a Digimon's special attack is triggered by "pendulum shaking" on the part of the human partner.
