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.
- Process "0": The first of a set of perpetually repeating processes which disassemble and reassemble the DigiCores of its opponents.
- Process "F": The last of a set of perpetually repeating processes which disassemble and reassemble the DigiCores of its opponents.
Dexmon is a large Digimon whose main body appears to be undefined. It has purple armor on its face, torso, elbows, and lower body similar to DexDorugoramon, as well as its red and black wings. Its lower body is large and bulbous, with red spikes that approximate feet emerged from the bottom and a green gem at its center. Its arms are extremely long and end in wickedly sharp claws.
- Death-X-mon (デクスモン)
