Dexmon

Dexmon is a Ghost Digimon and carrier of the X Antibody. Since it doesn't have its own DigiCore, this type of program cannot be classified as a Digimon, and although it appears solid, it has no actual substance. If it detects a DigiCore, it will absorb it into its body and disintegrate it, then reassemble it in a perpetually repeating set of processes named "Process '0'" through "Process 'F'". Although it is a simple program, it is conjectured that defeating it is within the realm of impossibility. Unless there are DigiCores nearby, it will go into stasis, but as long as there are DigiCores, it will not cease.[6]
