X-Antibody

The X-Antibody is a plot element from the CGI Japanese TV movie Digimon X-Evolution and related Digimon card games.

X-Antibody
When the Digital World becomes so overpopulated the super computer (Yggdrasil) that governs the Digital World can't handle it anymore. His solution? Wipe out the vast majority of the Digimon with the X Virus, he chooses a very small percentage to be moved to a new Digital World cause he plans to destroy the old Digital World. Those who were not chosen but survived anyway and moved to the new world had a rare gift known as the X-Antibody, this antibody when activated changed their appearance and made them more powerful.

Those who have the X-Antibody are generally disguished by the X in their name and sometimes an X placed on their body somewhere. There are few with the X-Antibody that isn't distinguished by an X after their name but this is because there is no version of them in existence that doesn't have the X-Antibody so there is no need to distinguish the normal and X-Antibody apart with the X surname.

The X Digimon fled to a new Digital World with 3 locations (the three locations are named after the Norns from Norse Mythology) consisting of Urd, a past plain which is a volcanic wasteland, inhabited by dinosaur and dragon Digimon, Verdandi is the present which is a world of lush greenery and is home to beast, bird, plant and other nature Digimon, and Skuld is the future, a high-tech city where machine and insect Digimon dwell. Yggdrasil sent the Royal Knights to eliminate the X Digimon.

Also, in America, Digimon with the X-Antibody are prominently featured in the card series Digimon: Operation X. Certain Digimon have the X Antibody, some Digimon are vulnerable to these Digimon, and another group of Digimon can easily destroy Digimon with the X-Antibody. Modify cards can also add, destroy, alter, or get power from the X Antibody.
