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.
The story is about Hikaru Ryuuji and his friends waking up into the digital world and trying to get back Dorumon's stolen dragon spirit before he dies. Story wise its very simple and not really any depth either as they just simply find bad digimon and fight them as they proceed. The art is a bit messy in some aspects as it made it a bit harder to follow what was currently happening but that doesn't necessarily make it bad. They introduce a different style to the digimon look and the characters have pretty good personalities which is the strong point of the manga, and
far as enjoyment goes it kept me entertained just enough to finish it so overall its a "fair" manga considering how short the story is.
Pokemon and Digimon came out at about the same time and both franchises share a similar concept, children partnering up with Digital/Pocket monsters to go on adventures and save the world. But what differences are there between these two series?
Yggdrasill, the god-like entity who runs the server that controls the Digital World. As powerful as he is, Yggdrasill cannot carry out these duties alone. To supplement the Digital World's security he calls upon the Royal Knights, a mighty order ready to lay down their lives to defend their home.
