The digital world you thought was safe turns into a culling ground. Yggdrasil isn't a mistake or a villain with understandable motives, it's the system itself deciding which Digimon deserve to exist, which ones are obsolete, and you watch helplessly as evolution becomes extinction. This is Digimon asking what happens when the game designer becomes the god with a delete button, and the answer arrives in X-Digimon that hunt the creatures you grew up with like they're glitching errors instead of life.
The Digital World is a virtual realm born from modern networks, home to Digimon and overseen by the host computer Yggdrasil. As the world grows too crowded for Yggdrasil to manage, it launches Project Ark: a plan to wipe out most Digimon with the X Program, move a chosen few to a new Digital World, and destroy the old one. Some Digimon who were never chosen survive anyway, changed by the rare X Antibody, which alters their appearance, boosts their power and makes them immune to the X Program. Branded outcasts in the new world, these X-Digimon are hunted by the Royal Knights, the protectors of the Digital Worlds who serve Yggdrasil. One X-Digimon searches for the meaning of its own existence while trying to protect the lives of all Digimon. Action-packed and existentially heavy, this film combines sci-fi world-building with genuine stakes for its digital characters.
