Digimon Chronicle X

Digimon Chronicle (X) (デジモンクロニクルエックス (X)) is a storyline created to promote the 2019 Digital Monster X and the 2020 Digital Monster X Version 2 featuring X-Antibody Digimon. The first four chapters were provided on the v-pet site, and were also compiled and expanded upon in the booklet packaged with the Digital Monster X. Chapters 5 through 8 followed close to a year later, also releasing online.

The story is a follow up to the original Digimon Chronicle, and focuses on the Royal Knights, who travel to the old Digital World. It has since been decimated by the X-Program, which was released by King Drasil ten years prior due to the vast amount of Digimon overpopulating the Digital World. To aid their journey, some of them are given the X-Antibody by King Drasil, transforming them into Kentaurosmon X, Craniamon X, and Jesmon X. They later get themselves into conflict with the Seven Great Demon Lords, who acquire the X-Program for themselves.
