Digimon World Re-Boot

Digimon World : Re-Boot is the continuation to the Digital Monsters saga, taking place about four years after the events of Digimon Data Squad. With the elimination of Yggdrasil, the super computer supposedly governing the Digital World, a new entity begins its move to bring about the enslavement of the human being, as well as the Digimons. Wanting to avert this terrifying disaster, a man, from the Digital World, summons eight children, The Digital Descendants, in hopes that 'history would repeat itself' and save the Digital world.

Story
Two years before the start of Digimon World Re-Boot, a mysterious substance was spread all over the Digital World. The substance, called Digital Cloud:Zero corrupted the DigiCores of any Digimon that came in contact with it. Soon the Digital World was in turmoil. The corrupted digimon became violent and aggresive, losing all manners of speech. They started to attack other digimon, both the corrupted ones as well as the non-corrupted ones. The Royal Knights intervened, and fought off as much corrupted digimons as they can, but soon fell, one by one, after UIForceVeedramon and Examon got corrupted themselves.
